by Maryam Baghdadi 27 Dec '21

27 Dec '21

Hello everyone, I have a problem over running local docker images of Kamailio in Kubernate cluster.. Consider I build a local docker image from Kamailio and create a pod in one of my nodes . My process created successfully and Kamailio listen over port 5060 now I need to rebuild another docker image with new Kamailio configuration and run it as another pod with new name and listening over port 5061 but I have error "ImagePullBackOff" . I test this scenario many times but problem exists.. It is devastating for me and I need emergency help.

Kamailio Stop processing SIP traffic
by pwerspire 27 Dec '21

27 Dec '21

Hi, I have been doing some load testing with Kamailio and having some issues. I have been trying with 100 CPS and at the beginning, everything is working well but after some time (it can be 10 minutes or for example 40 minutes, is just random but normally happens more in the first 10 minutes) Kamailio stop replying to all SIP messages but still processing HTTP requests, some commands, etc. If I use "kamcmd dlg.list" no output happens and after that, all kamcmd commands just keep loading with no output. Kamailio is sharing Dialogs and htables using DMQ with other Kamailio that is the failover, if I shut down the failover one (so no DMQ replication), the test works well with the 100 CPS. Also tried with modparam("dmq", "worker_usleep", 1000) but the behavior is the same, it will stop processing traffic. This is some of configuration used: # ----------------- setting module-specific parameters --------------- modparam("dmq", "server_address", "sip:INTERNAL_INSTANCE_IP:5060") modparam("dmq", "notification_address", "DMQ_NOTIFICATION_ADDRESS") modparam("dmq", "multi_notify", 1) modparam("dmq", "ping_interval", 10) modparam("dmq", "num_workers",4) modparam("htable", "enable_dmq", 1) modparam("htable", "dmq_init_sync", 1) # ----- dialog params ----- modparam("dialog", "dlg_flag", FLD_DLG) modparam("dialog", "dlg_match_mode", 1) modparam("dialog", "db_url", DBURL_RW) modparam("dialog", "db_mode", 0) modparam("dialog", "enable_dmq", 1) modparam("dialog", "db_update_period", 10) modparam("dialog", "h_id_start", H_ID_START) modparam("dialog", "h_id_step", H_ID_STEP) Memory: Shared: 4096 Private: 512 kamailio -v version: kamailio 5.5.3 (x86_64/linux) 473cef flags: USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLOCKLIST, HAVE_RESOLV_RES, TLS_PTHREAD_MUTEX_SHARED ADAPTIVE_WAIT_LOOPS 1024, MAX_RECV_BUFFER_SIZE 262144, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: 473cef compiled on 09:34:57 Dec 20 2021 with gcc 10.2.1 In attach is the trap collected after the issue happens.

Active/active keepalived - Kamailio includes non-local virtual IP in "myself" which breaks DMQ call routing
by Rhys Hanrahan 22 Dec '21

22 Dec '21

Hi Everyone, I have Kamailio acting as a registrar, using DMQ to replicate usrloc between nodes. I’m relaying INVITEs to the home registrar, but skipping this if (uri == myself) is true. In my lab I just setup my SBCs in an active/active mode, similar to the link below. So I have 2x VIPs and both SBCs listen on both, but the first VIP is only master on SBC01 and the second VIP is only master on SBC02. https://docs.nginx.com/nginx/admin-guide/high-availability/ha-keepalived-no… My issue is that now “myself” will always return true even if the virtual IP is actually not active on this node at the moment, so the invite is never relayed properly if it’s on another node. I guess “myself” is just blindly looking at the list of Ips that are configured with either listen= or alias= and doesn’t care if the IP actually exists on the server at the time, or not? I am thinking I may have to ditch relying on “myself” entirely and come up with some other way of checking for local requests, but I am wondering if there’s a good way of approaching this? I was thinking of perhaps triggering an add/remove of listen directives (or something) when a failover of a VIP happens, though this seems kind of heavy handed. Hoping there is a better way. Has anyone else tried doing active/active Kamailio instances like this? Thanks!

Issue Bug in SEMS (transparent SBC profile)
by Mojtaba 21 Dec '21

21 Dec '21

Hello, Why in SEMS, some changes (in transparent SBC profile) in sip headers do not apply. For example i want to change CSeq or Contact header like this: # transparent SBC profile # defaults: transparent RURI=$r From=$f To=$t Call-ID=$ci_leg2 CSeq=$H(CSeq) Contact=$H(Contact) When I run SEMS, CSeq and Contact do not change, while other headers change. [#7fc688d7b1c0/9379] [onLoad, SBC.cpp:189] INFO: loading SBC call profiles from '/usr/local/etc/sems/etc/' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:418] INFO: SBC: loaded SBC profile 'mo' - MD5: d6a2c29084043edde1357231f6866737 [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:423] INFO: SBC: RURI = '$r' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:424] INFO: SBC: RURI-host = '' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:425] INFO: SBC: From = '$f' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:426] INFO: SBC: To = '$t' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:431] INFO: SBC: Call-ID = '$ci_leg2222' [#7fc688d7b1c0/9379] [readFromConfiguration, SBCCallProfile.cpp:434] INFO: SBC: force outbound proxy: yes This issue caused the Asterisk could not pass the Authentication process in "match_req_to_dialog" function because the CSeq is the same as the dialogs. So the Asterisk thought this message was a LOOP message. Has anybody encountered this issue in SEMS? How did you solve this?

uac module - use htable instead of database
by Markus Bönke 20 Dec '21

20 Dec '21

Hello all, we want to use the "remote registrations feature" of the uac module to let kamailio register with other sip providers. As far as I see the module works only with a database backend. As our kamailio script should be independent from a database, a solution could be to load the configuration on startup (and refresh it periodically) from a database view into a htable and then trigger the remote registrations based on the expiration of the htable columns. Could something like this be implemented by using the uac module or by an other workaround ? Or does it require some enhancements in the uac module ? Thanks and regards Markus

Using kamcmd tm.t_uac_start to send SIP REGISTER messages in Kamailio 5.5
by Steve Sether 20 Dec '21

20 Dec '21

I'm trying to use the kamcmd tml.tc_uac_start command to send raw SIP messages in Kamailio 5.5, but I always get a error: 400 - Invalid headers. I've also tried sending OPTIONS messages with the same result. I've looked for examples of sending SIP messages via kamcmd, but can't find any. kamcmd help tm.t_uac_start specifies the following: kamcmd> help tm.t_uac_start starts a tm uac using a list of string parameters: method, ruri, dst_uri, send_sock, headers (CRLF separated) and body (optional) Essentially my problem is I don't really know how to properly encode these headers. How do I send special characters? Do I need to use double quotes, single quotes, etc around the whole header? Which characters are special? How do I encode the CRLF? I tried \r\n, but I still get this error. It says only From: and To: are required. It's a bit hard trying to make progress when all I ever get is one error message. The kamailio logs are a little more helpful, and largely point me down the road that it doesn't understand the CRLF encoding, and says my From: header includes the To: line, so it's not separating them. For example, I'm trying things like this: kamcmd -v tm.t_uac_start OPTIONS sip:200@exampleserver.com:5060 . . "From: <sip:example@192.168.0.1>;tag=d27ca05e-1789-4774-a698-dcfe91dec9b4\r\nTo: <sip:example@192.168.0.2>"\r\nExpires: 1200\r\nContent-Length: 0" Nothing seems to work, so whatever the syntax I'm using must be wrong. Just providing an example of sending SIP via kamcmd tm.t_uac_start would likely help a huge amount. Thanks! --

tcp_set_connection_lifetime(1) does not close connection
by Sebastian Damm 19 Dec '21

19 Dec '21

Hi, for having a maintenance mode, I need to implement some sort of draining functionality. All our clients register via TLS. So I thought, I just answer the next REGISTER of a client with a 503 and kill the tcp connection afterwards, so they need to open up a new connection to the loadbalancer in front and end up on a different server. This is my code: 510 if msg.is_method("REGISTER"): 1 if KSR.pv.get("$shv(MAINTENANCE_MODE)") == 1: 2 KSR.info("In maintenance mode, rejecting registration") 3 KSR.hdr.append_to_reply("Retry-After: 2\r\n") 4 KSR.sl.sl_send_reply(503, "Draining") 5 if KSR.tcpops.tcp_set_connection_lifetime(1) > 0: 6 KSR.info("Set Connection lifetime to 1") 7 return False (Side note: msg is some internal class, this is obviously KEMI with python) So now when I set the MAINTENANCE_MODE var to 1, Kamailio rejects the REGISTER requests, logs both lines and sends out a 503. Debug log tells me this: Dec 10 15:32:10 ifens5 /usr/sbin/kamailio[3851]: DEBUG: tcpops [tcpops.c:229]: tcpops_set_connection_lifetime(): new connection lifetime for conid=1: 908866403 Dec 10 15:32:21 ifens5 /usr/sbin/kamailio[3855]: DEBUG: <core> [core/tcp_main.c:4554]: tcpconn_main_timeout(): entering timer for 0x7f759cb26218 (ticks=908866499, timeout=908866499 (0 s), wr_timeout=0 (211631299 s)), write queue: 0 bytes In tcpdump I can see that the connection does not get closed immediately. Is there some timer in the tcp stack which cleans up expired connections from time to time? Can I manipulate how often this timer runs? I couldn't find anything, and clearly even though I tell Kamailio to close the connection after 1 second, it doesn't do it. Thanks for any input. Regards, Sebastian

ACK is sent to wrong address when using serial forking
by Minh Phan 15 Dec '21

15 Dec '21

Dear List, As shown in the image below, Proxy 1 tries to do serial forking to Proxy 3 and then Proxy 4. Upon reception of the 480 answer ( blue frame) from Proxy 2, the Proxy 1 generated an ACK (red frame) and sent it to Proxy 1. The problem I have is that the ACK generated by Proxy 1 has a wrong RURI. I expect the ACK to be sent to the URI of the CONTACT header of the 480 message (blue frame). However, its RURI is the same as the one in the first INVITE of the dialog. Note that there is NO ROUTE header in the ACK message. As there is serial forking here, the ACK is generated by the Proxy 1 itself. Any hint would be appreciated, Best Regards, Minh Phan [image: image.png]

RTP Proxy with Local IP and Public IP
by Vijo Jose 13 Dec '21

13 Dec '21

Hai Everyone. I have configured the RTP Proxy with Kamailio SIP Proxy Server. Where I have my Kamailio is configured with private IP 10.0.0.1 and Public UP 103.XX.XX.XX and the SIP user is connecting with RTP proxy with local IP 10.0.0.1 to register. I also have a SIP Asterisk server on the public Internet with IP 90.XX.XX.XX that makes the call to sipuser@103.XX.XX.XX:5060 which is coming on the sip proxy server and the sip proxy server forwards those packets to the SIP user who is registered with local IP 10.0.0.5. Once the call is answered the RTP is started to send from the SIP server to the SIP Proxy server over the public IP from 90.XX.XX.XX to 103.XX.XX.XX which is working as expected. But from the sip user 10.0.0.5 the RTP is flowing to Proxy server public IP 103.XX.XX.XX instead of RTP Proxy server Localip 10.0.0.1. How can we configure the same? Presently I have started my RTP proxy server with command /usr/local/bin/rtpproxy -F -A 103.XX.XXXX -l 10.0.0.1 -m 10000 -M 20000 -s udp:127.0.0.1:7722 -d DBUG:LOG_LOCAL5 Thanks in advance.

remove rport in INVITE Via HDR and make kamailio behave asymmetric
by Nuno Miguel Reis 11 Dec '21

11 Dec '21

Hi guys. I've a scenario here where I'm receiving inbound traffic from a Mitel PBX on a LAN environment with a bunch of router hops between kamailio and the Mitel. Sometimes, not always, I get traffic from the MItel PBX where the source port is changed in transit (some kind of NAT, still don't know where exactly) from 5060 to a dynamic port different from 5060. Every INVITE comes with rport in via header as: .. Via: SIP/2.0/UDP 10.21.252.35:5060 ;branch=z9hG4bK-524287-1---d6bac01809527627*;rport* .. when this happens kamailio sends all the replies to the $si:$sp symmetrically (force_rport behavior) and I would like to force the opposite instead, making it asymmetric and sending the traffic to $si:5060 everytime. I'm having a hard time forcing the *unforce*_rport() behavior. Does anyone have a good suggestion for this? Looking forward to hear from you. Cheers, -- Nuno Miguel Reis Departamento de Engenharia Informática Faculdade de Ciências e Tecnologia Universidade de Coimbra

Unquoted values from #!defenv
by Ben Kaufman 09 Dec '21

09 Dec '21

Hello all, Looking for some clarification regarding quoting and !#defenv . I understand that the example below fails because the environmental variable HOME is not quoted, thus when used in the xlog() call it fails. How is it possible to evaluate and/or use the value of the environmental variable if defined as a preprocessor variable? Looking at the documentation the reason for this directive is "It is a simplified alternative of using #!substdef with $env(NAME) in the replacement part." But #!substdef would allow setting the value inside of a quoted string, so does it really meet that requirement? I'm aware that I could use $env(HOME) rather than a preprocessor directive of HOME. I'm just trying to understand the usage of the #!defenv feature. #!KAMAILIO ## Tested in 5.5.2 loadmodule "xlog" loadmodule "pv" loadmodule "evrexec" modparam("evrexec", "exec", "name=evrexec:timer;wait=1000;workers=1;") #!defenv HOME request_route{ forward(); } event_route[evrexec:timer] { xlog("L_N", "HOME: " + HOME + "\n"); } Ben Kaufman

Kamailio v5.3.9 Released
by Daniel-Constantin Mierla 08 Dec '21

08 Dec '21

Hello, Kamailio SIP Server v5.3.9 stable release is out. This is a maintenance release of the old stable branch, 5.3, that includes fixes since the release of v5.3.8. There is no change to database schema or configuration language structure that you have to do on previous installations of v5.3.x. Deployments running previous v5.3.x versions are strongly recommended to be upgraded to v5.3.9 or even better to v5.4.x or 5.5.x series. For more details about version 5.3.9 (including links and guidelines to download the tarball or from GIT repository), visit: * https://www.kamailio.org/w/2021/12/kamailio-v5-3-9-released/ RPM, Debian/Ubuntu packages will be available soon as well. Note: the branch 5.3 is an old stable branch, v5.3.9 being the last planned release out of it, to mark the end of official maintenance. The maintained stable branches are now 5.4 and 5.5, at this time with v5.5.3 being the latest stable release. Many thanks to all contributing and using Kamailio!

Hello, it is time to mark the end of official packaging for 5.3.x releases, therefore during the next days I am going to cut the v5.3.9 release from branch 5.3, likely on Wednesday, Dec 8, 2021. In other words, if no major regression is detected shortly after this release, the v5.3.9 is going to be the last one from the 5.3 branch. It is strongly recommended to move to a series that is under active maintenance, respectively 5.5.x or 5.4.x.

HTTP Requests for API routing - Question on which module to use with KSR
by Emilio Panighetti 08 Dec '21

08 Dec '21

Looking into using Kamailio to route calls via an HTTP API. Basic scenario is this: INVITE comes in (no registration). And Kamailio sends an HTTP request to a server with data extracted from the INVITE. Based on the response, call KSR.setdsturi() and other actions like normalizing phone numbers, etc. (Not sure if changing Contact: headers would be a better option). For now I want to be able to make a simple call routing as a proof of concept. Planning on using Lua as a KEMI interpreter. Looking at different modules: http_client http_client_async xhttp Which module would be more appropriate? http_client_async provides a simple async method and callback, so the SIP threads can continue processing requests while the API server is preparing the response. But the call has to be parked (How is this done?) and this is also an overhead. http_client seems straightforward, but the SIP threads are tied up waiting for HTTP responses. Also looking at the KEMI documentation, the KSR function calls for HTTP_CLIENT doesn’t seem to match the config function documentation. For example, In KEMI manual: KSR.http_client.curl_connect_post() doesn’t have a corresponding in kamailio.cfg. So which would be the preferred approach? Also examples would be appreciated. Thanks in advance!

Manipulation of request-line
by Mihovil Kolaric 07 Dec '21

07 Dec '21

Hi, I have an issue with a SIP-client, that occasionally puts a blank between the version SIP/2.0 and the CRLF at the and of the request-line. (i.e. sends "ACK <uri> SIP/2.0 \r\n" instead of "ACK <uri> SIP/2.0\r\n"). Kamailio (as well as most SIP UAs) does not care about that error and successfully processes/forwards the request (also when using sanity_check()). But I also deal with a client that fails to parse that request. (Furthermore, wireshark's dissector fails to recognize such malformed messages as SIP, which makes debugging even harder). I tried to fix this issue using textops, but all functions I tried operate only on headers or message body, but do not seem to affect the request line. Is there any possibility to modify the request-line, or to replace it with a new one? Best Regards, Mihovil

detecting compact headers?
by Brooks Bridges 06 Dec '21

06 Dec '21

We have an internal component of our callflow that does not support compact headers (vendor says it's on the roadmap but no eta, etc) so I'm trying to find a clean way to detect if a message has compact headers and reject it. I haven't had much luck in finding a way to identify specifically if any of the headers of the message are compact however. Can anyone point me in a direction please? Thanks!

DMQ Usrloc/Dialog - Experiences
by Carsten Bock 03 Dec '21

03 Dec '21

Hi, I wanted to quickly ask the group about experiences with DMQ and Usrloc/Dialog. I don't expect any issues when choosing such an approach, especially since we would have re-transmits for a message (fr_timer = 30 seconds) if we did not receive any answers or scenarios alike. So I assume, having short "outages" (less than 30 seconds) for the communication is just fine. So far I used DMQ in a non-IMS setup for synchronizing usrloc with ~15k Subscribers and it worked really well. One concern brought up (not by me) was, that synchronizing usrloc with DMQ might not be reliable at scale. I would also love to understand how to treat situations when the communication is lost for a longer period of time (e.g. if the communication between nodes is lost for 5 minutes?). Can anyone share some real-life experiences?

topos xavu_field_contact_host kamailio 5.5
by Jonathan Hunter 03 Dec '21

03 Dec '21

Hi All, I was wondering if anyone can help, and advise me if I am missing something when using topos in an environment where I have more than one interface for kamailio. Essentially I would like to set the contact_host to 2 different values depending on the flow of the SIP requests, as we have a private LAN interconnect for example 10.10.10.10, and a public interconnect using 2.2.2.2 (for example). I notice there is xavu for A-side contact and B-side contact, but what about just the contact host? As I have set for example; modparam("topos", "xavu_cfg", "_tps_") modparam("topos", "xavu_field_contact_host", "contact_host") ... $xavu(_tps_=>contact_host) = "2.2.2.2"; And this works fine but obviously sets the contact_host to 8.8.8.8 across both interfaces, I ideally want it to change between 10.10.10.10 and 2.2.2.2. How can I set more than one contact_host $xavu that topos can use? As my understanding is you can only set $xavu once, so is there another way to manipulate the contact_host on requests coming in and out on different interfaces? I assume I am missing something? :) Thanks in advance Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows

no the problem appear to be with the advertise this makes all listeners listen = PRIV_SOCK advertise MY_PUB_SOCK name = "ext" but listen = PRIV_SOCK_TLS advertise MY_PUB_SOCK_TLS name = "ext_tls" is failing with a look up error on MY_PUB_SOCK_TLS if I try : listen = PRIV_SOCK_TLS advertise "MY_PUB_SOCK_TLS" name = "ext_tls" it fails on a lookup for what ever the def is for that variable e.g. 1.2.3.4:5061 the defs are of the correct syntax if it replace the defs it works e.g listen = tls:10.10.10.10:5061 advertise 1.2.3.4:5061 name = "ext_tls" the two defs math the text above the problen is its working for the "global" defs without any protocl, so its making the tls listener for the wrong port as 5060 so listen = LISTEN_EXTERNAL_SOCKET advertise ADVERTISE_NAT_ADDRESS name = "ext" is working with #!substdef "!LISTEN_EXTERNAL_SOCKET!10.10.10.10:5060!g" and #!substdef "!ADVERTISE_NAT_ADDRESS!1.2.3.4:5060!g" the _TLS versions are not changing the tls port so i have tls on port 5060 when iot should be on 5061 and the name ext_tls where all other sockets are called "ext" Regards, Richard On 30/11/2021 20:03, Karsten Horsmann wrote: > Hi Richard, > > Hmmm for some reason I split my vars into parts. > > And you prefix that with tls?

Using path with DMQ to send calls to origin SBC - not sure when to modify destination URI
by Rhys Hanrahan 01 Dec '21

01 Dec '21

Hi Everyone, I am trying to add DMQ for redundancy of registrations and USRLOC, and I’m trying to send calls to the correct SBC that is the original registrar for a handset. I’ve been using the thread here where Charles gave some guidance on how to use path to store and use the original SBC: https://lists.kamailio.org/pipermail/sr-users/2018-February/100246.html and https://lists.kamailio.org/pipermail/sr-users/2013-September/079736.html I am struggling with when to decide to modify the destination URI. My testing shows this is required otherwise some handsets will ignore the invite, but right now I am doing it in a blanket form, right before SIPOUT (which is where the origin SBC handles the invite instead of LOCATION). I am sure this is being too heavy-handed though and there are some cases where I won’t want to set this, but I am not sure which? # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) { record_route(); } … xlog("Setting du according to path. Current du is $du\n"); xlog("Current route header: $(hdr(Route))\n"); xlog("Current route: $(hdr(Route){uri.host})\n"); >>> $du = $(hdr(Route){param.value,received}); #xlog("New du destination uri is: $du\n"); # dispatch requests to foreign domains route(SIPOUT); In the linked threads, Charles mentioned that only the last-hop registrar should make this change, but what’s the best way to determine if I am on the last-hop registrar? As per the snippet above, I tried using the {uri.host} transformation to extract the origin SBC’s IP from the route header. My plan is to then compare this against “myself” but I am struggling to extract the right info from the route header. And I am not even sure if this is the right general approach? The route header looks like this: <sip:ORIGIN_SBC_IP:5060;received=sip:UAC_WAN_IP:2048;lr> Any guidance or examples would be appreciated. Thanks!

Re-writing presentity domain for DMQ
by Rhys Hanrahan 01 Dec '21

01 Dec '21

Hi Everyone, I am trying to get DMQ working for presence/dialog notifications. Presence works fine locally on the same SBC. The DMQ part itself is also working fine and I can see that the entries in presentity are being replicated between my DMQ nodes. The problem is that when the presentity records are being replicated from another SBC, the domain for that record stays as the IP of the original SBC. Then when the local_watchers is populated, the presentity_uri doesn’t match, and no NOTIFY packets are sent as a consequence. What am I missing here? I can’t see anything in the docs about how to handle this, and I can’t find any examples in the list on how to handle this either, which suggests it isn’t as common of an issue at it seems. See example of what I see in the presentity table below. In this case handset 103 is subscribed to BLFs for 103 and 104. A call came into 103 and generated an early state dialog in the presentity table. MariaDB [kamailio]> select * from presentity; +-------+-------------+--------------+--------+-- | id | username | domain | event | +-------+-------------+--------------+--------+-- 27100 | nexusone103 | x.x.x.53 | dialog | I have modified my registrations and have re-written my SUBSCRIBE and PUBLISH packet headers so that everything uses a common FQDN for both SBCs, that does DNS RR to both SBC IPs. I am also registering from the handset using this FQDN now, and yet although my active_watchers table now expects a presentity URI of XXX(a)sbc.fqdn<mailto:XXX@sbc.fqdn>, the presentity table is still using the IP addresses of the individual node that originated the dialog. MariaDB [kamailio]> select presentity_uri,watcher_username,watcher_domain,event from active_watchers; +----------------------------------------------+------------------+----------------------+-----------------+ | presentity_uri | watcher_username | watcher_domain | event | +----------------------------------------------+------------------+----------------------+-----------------+ | sip:104@sbc.fqdn | nexusone103 | sbc.fqdn | dialog | | sip:103@sbc.fqdn | nexusone103 | sbc.fqdn | dialog | +----------------------------------------------+------------------+----------------------+-----------------+ I’m out of ideas unfortunately. Any advice would be appreciated. Thanks!

Kamailio and RTPEngine acting as SBC : wrong IP address returned
by Cyril Ramière 28 Nov '21

28 Nov '21

Hi there, I'm already using Kamailio as a simple proxy and it worked flawlessly. This time, I need to have a new setup like this: [UAC (sip phone)] <--- register & has to deal only with ----> | PUBLIC | [Kamailio + RtpEngine] | PRIVATE | <----> [Asterisk] Client = 37.100.100.100 (public) Asterisk = 172.17.200.20 (private) Kamailio/RtpEngine = 172.17.203.102 (private, advertising 3.99.99.99 public IP) Kamailio and RtpEngine will behave as a SBC/B2BUA, the client will deal only with kamailio using public access (internet), and asterisk will handle the calls but stays 100% private behind kamailio. Kamailio will handle registrations to reduce the load put on the asterisk boxes. The setup is running on AWS, my Kamailio has 1 Private IP address tied to 1 Public IP address (an Elastic public IP) so, no multi-homing, one network interface. I made a "simple" work in progress configuration, the registration is working as a PoC, and my calls are *almost* working but with some nonsense. My Main issue is that when my UAC (SIP phone) make a call, to let's say +1000, the call enters kamailio, then kamailio handle the invite, trigger rtpEngine, but the IP addresses in Record-Route and Via headers are wrong. >From Kamailio to UAC Sip Phone, it seems OK. But from Kamailio to Asterisk, the record-route/via headers are set with Kamailio Public IP when it should be the Kamailio private IP. So, when Asterisk sends a BYE, it tries to send it to the public IP of Kamailio, which is wrong. There are probably other quirks in the configuration but this one, I can't figure out what's wrong. I'm attaching a capture file, a log file and my configuration file (some informations are redacted). I am missing something and sadly I can't figure out what, a little help would be appreciated :) Regards

Problem implementing Outbound Proxy
by Christoph Russow 26 Nov '21

26 Nov '21

Hi all, im currently trying to add a Outbound Proxying to our system which right now does inbound loadbalancing for our application servers. Current: Inbound SIP Trunk -> Kamailio -> dispatcher -> ApplicationServer 1..n i now want to add the ability for our internal Application Servers to terminate their outbound calls through the kamailio system. currently i've setup a gateway in the (freeswitch) application server that has the kamailio system set as outbound-proxy. this leads to sip calls started with originate sofia/gateway/kamailio/<number>@<outbound carrier IP> to be sent to the kamailio system which then forwards it to the given carrier IP. Sadly our main carrier answers with "503 service unavailable - no bandwith available". (maybe due to the internal ip-addresses within some of the headers?) i've attached our current kamailio configuration and also a pcap of a call i tried to start with our main carrier. i tried this way as it seemed to be the easiest way so our application servers still can select the outbound carrier within their flow. maybe i'm on the wrong way here and need to solve this problem in a completely different way i don't know. TLDR: sip proxying does not work as expected. need a way to achieve outbound calls routed through kamailio from internal application servers any hint/help into the right direction is appreciated Best Regards Christoph Russow -- ________________________________________________________________ EMTEX GmbH Christoph Russow Software Engineer Bischof-Otto-Weg 9 D-91086 Aurachtal Geschäftsführer: Markus Enzinger Tel. +49 9132 7490 0 Sitz der Gesellschaft: 91086 Aurachtal Fax. +49 9132 7490 900 Amtsgericht Fürth: HRB6804 ________________________________________________________________

Call limiting with Kamailio
by Olli Attila 26 Nov '21

26 Nov '21

Hello, What choices do I have to implement a feature to Kamailio which would limit calls per customer? The environment: Two kamailio nodes sitting in different sites and they are not aware of each others sessions/dialogs and thus serving customer calls independently. Configurations on the nodes are identical excluding ip addresses. Customer call can be routed through either one of these Kam nodes. The two nodes share a common external mysql database from which all dialplan and htable entries are loaded (used in call routing for example). Customers are identified based on IP address & tel numbering and as a final result we are populating an variable which holds the customer id $var(REALM_NAME) when the identification has been done. The call limiting should be "tagged/profiled" somehow with this information if possible. Any suggestions which way to go with this? Initial ideas if one of these are worth of setting a starting point: -> Counting calls with htable and replicating with DMQ to other node (can the data survive from a restart?) -> Using the common mysql database to hold the counted calls from where both kam nodes could load data? (database load increasing?) -> Some new exciting module for this job? Cheers, Olli

Re: [SR-Users] How to not write logs to journald with kamailio
by Ginhoux, Patrick 26 Nov '21

Hi, I resend this mail because of the initial destination address was not correct. The topic was a logging problem : With the upgrade of my SIP Router proxies to RHEL 7 (and Kamailio 5.0.7) , we encounter problems where the logs are blocked to be written in the syslog.

LCR Module not loading all rules from DB
by Juha Heinanen 25 Nov '21

25 Nov '21

If your db supports DB_CAP_FETCH, lcr rules are loaded from the db 1024 rows per cycle. You could check what you get to syslog from this statement after you set log level to debug level and then execute lcr.reload: LM_DBG("loading, cycle %d with <%d> rows\n", n++, RES_ROW_N(res)); -- Juha

Problem with 302
by nathan Kirk 24 Nov '21

24 Nov '21

Hello, First time poster and I am stuck. I am using K as a mid registar to several AST boxes. The problem I am having is if AST or the END USER DEVICE sends a 302 for some reason I am getting a 500 THEN the 302 to the END USER DEVICE or AST depending which direction the call flow is. Example END USER DEVICE -> CALLS 700 -> K -> AST AST -> 302 -> K -> 500 & 302 -> END USER DEVICE What I would like to happen is when K receives the 302 it deals with it directly and it is not handed off to either end. I am using a configuration I found online with some base modifications to dip into the database real time to get the AST box IPS Any direction would be helpful. Thank you, Nathan

t_suspend() / t_continue() create new branches
by Sebastian Damm 24 Nov '21

24 Nov '21

Hi, I have the following weird problem. A Kamailio (5.4.x) with some asynchronous permission logic suspends outgoing INVITEs and resumes them after the answer of the permission system. Everything works as expected when the call is answered. However, when the called party rejects the call (with a 486 for example), the call doesn't get torn down immediately (it is rejected with a 408 eventually) because Kamailio logs the following: Nov 23 14:51:02 host /usr/sbin/kamailio[1569]: DEBUG: app_python [apy_kemi.c:106]: sr_kemi_config_engine_python(): execution of route type 4 with name [ksr_onreply_manage] returned 1 Nov 23 14:51:02 host /usr/sbin/kamailio[1569]: DEBUG: tm [t_reply.c:1363]: t_should_relay_response(): ->>>>>>>>> T_code=183, new_code=486 Nov 23 14:51:02 host /usr/sbin/kamailio[1569]: DEBUG: tm [t_reply.c:1448]: t_should_relay_response(): store - other branches still active Nov 23 14:51:02 host /usr/sbin/kamailio[1569]: DEBUG: tm [t_reply.c:1926]: relay_reply(): reply status=3 branch=2, save=1, relay=-1 icode=0 msg status=486 I don't do any forking, the call is just forwarded. I put the following line immediately after t_suspend() and in the beginning of the route specified in t_continue(): KSR.info("We're at branch index %d" % KSR.pv.get("$T(branch_index)")) This produces the following output: Nov 23 16:30:13 host /usr/sbin/kamailio[2745]: INFO: <core> [core/kemi.c:104]: sr_kemi_core_info(): We're at branch index 0 Nov 23 16:30:13 host /usr/sbin/kamailio[2725]: INFO: <core> [core/kemi.c:104]: sr_kemi_core_info(): We're at branch index 2 So apparently, the suspend and continue introduce new branches. (Other option: I'm doing something completely different creating those branches, but I don't have any append_branch() or similar in my code.) I assume, I just missed a configuration parameter. Can I get Kamailio somehow to behave as if there was just one branch and forward the negative reply? Thanks, Sebastian

[uac] How to force outbound registration?
by Denys Pozniak 24 Nov '21

24 Nov '21

Hello! In some cases, I need to forcibly unregister a remote SIP account through uac module, and then immediately register. To unregister I can use the command: *kamcmd uac.reg_unregister l_uuid <account>* But it's not clear how to immediately register back. For example, these commands do not give the desired effect: *kamcmd uac.reg_enable l_uuid <account>* *kamcmd uac.reg_reload* [root@kamailio]# kamailio -V version: kamailio 5.5.2 (x86_64/linux) 55e232 -- BR, Denys Pozniak

UDP packets lost - tuning Linux system configuration - Kamailio using default for SO_RCVBUF ?
by Chaigneau, Nicolas 23 Nov '21

23 Nov '21

Hello, I'm using Kamailio 5.5.2 with UDP sockets, configured with 32 children processes. During load tests, some packets seem to be dropped. I'm trying to figure out why, and how to solve (or mitigate) the issue. >From what I understand : < the SIP messages send on UDP/SCTP are received directly from the buffer in kernel one by one, each being processed once read. > (this is a message from Daniel-Constantin Mierla, posted on the mailing list back in 2014 - I assume this is still accurate) So Kamailio does not handle its own buffers for incoming messages, but simply pulls one message from the kernel queue whenever a process is available for processing. (Correct me if this is not true) Hereafter some system parameters that seem interesting to me. In particular, < net.core.rmem.default > seem very low (0,33 MB). But < net.core.rmem.max > is much higher (16 MB). Looking at the code in function probe_max_receive_buffer (src\core\udp_server.c), it seems Kamailio is trying to increase the buffer size from the default. However this does not seem to be working, seeing the following logs upon startup : 0(7602) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 349520 0(7602) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 349520 0(7602) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 349520 0(7602) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 349520 0(7602) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 349520 0(7602) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 349520 Is there something I don't understand ? could it be a bug ? One quick fix I can think of would be to increase < net.core.rmem.default >. Considering that I don't have many sockets (3 used by Kamailio), I think I could set this to 16 MB (my VMs have 8 GB of allocated RAM). What do you think ? Thanks in advance for your help. My system parameters : net.core.rmem_default = 349520 net.core.rmem_max = 16777216 # => 0,33 MB / 16 MB respectively * net.core.rmem_default, net.core.rmem_max - default and max socket receive buffer size in bytes. Each socket gets rmem_default reveive buffer size by default, and can request up to rmem_max with setsockopt<http://man7.org/linux/man-pages/man2/setsockopt.2.html> option SO_RCVBUF. net.ipv4.udp_mem = 188856 251809 377712 * net.ipv4.udp_mem = "min pressure max" - these are numbers of PAGES (4KB) available for all UDP sockets in the system. min, pressure and max controls how memory is managed, but main point is that max is maximum size in PAGES for all UDP bufers in system. These values are set on boot time (if sysctls are not explicitly set) according to available RAM size. # 377712 x 4 KB => 1475 MB net.ipv4.udp_rmem_min = 4096 * net.ipv4.udp_rmem_min, net.ipv4.udp_wmem - minimal size for receive/send buffers (in bytes), guaranteed for each socket, even if if buffer size of all UDP sockets exceeds pressure parameter in net.ipv4.udp_mem.

Custom info in Contact header

Hello! On REGISTER I have a Contact header like Contact: <sip:90002@192.168.0.26:48579;transport=TLS>;some_id=90002-21080 But on calling fix_nated_register() -> save(), param some_id is lost from info, so, on INVITE to this account, some_id not appears in RURI.

Help with Async transaction responses
by Michael Friesen 19 Nov '21

19 Nov '21

Hello, I am attempting to perform some asynchronous lookup upon receiving an INVITE and then reply with a 3xx response with a modified From header. My workflow now is to create a transaction when receiving the INVITE, suspend the transaction, perform the asynchronous lookup, continue the transaction upon response, and then modify the From header and reply. The ONLY problem I am having is modifying the From header! How can I modify the From header in this scenario? function ksr_request_route() if KSR.is_INVITE() then if KSR.tm.t_newtran() then cache_transaction_info() KSR.tmx.t_suspend() --perform async loookup end end return 1 end --This function called on response from async lookup. Equivalent of ONREPLY_ROUTE function ksr_reply_route() --Finds the transaction_index and transaction_label from a cache KSR.tmx.t_continue(transaction_index, transaction_label, "redirect_transaction"); KSR.x.drop() return 1 end function redirect_transaction() KSR.pv.sets("$fU", "Jenny") --Doesn't actually modify the from username for 302 response! KSR.tm.t_reply(302, "Redirecting") return 1 end Thank you much! -Michael

corex send()
by Ross McKillop 12 Nov '21

12 Nov '21

Hi All, Is there an equivalent to corex's send_tcp (https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp <https://kamailio.org/docs/modules/5.2.x/modules/corex.html#corex.f.send_tcp>) for TLS? I have a bit of an odd edge case where I can't add Via headers etc, and send_udp and send_tcp allow me to achieve what I want, but it doesn't seem to have a means of doing the same with TLS? Essentially I want to transparently proxy what is received by Kamailio on one interface to a TLS connection e.g. A = (TCP) => Kamailio = (TLS) => Remote Host (A) in this instance is already setting a Via header of the Kamailio's external IP and transport tis. I appreciate this is a non-standard way of doing it, but (A) is a black box that I can't change, what I'm essentially trying to do is have Kamailio handle the TLS but essentially (A) thinks it's at the edge. I can make it work with send_tcp for a standard TCP connection, but if I use t_relay or even forward() to send onwards by TLS then Kamailio obviously adds its own headers as you'd expect. Ross

Kamailio dropping ACKs
by Emilio Panighetti 12 Nov '21

12 Nov '21

Working on a proof of concept with Kamailio 5.5.2 (Installed via kamailio-5.5.2-0.el8.centos.x86_64 RPM from rpm.kamailio.org). Also note that this is using the LUA interface Running a simple SIPp scenario without registration. Routing is set with in Lua: KSR.dbg("EP: ksr_route_relay Check for Base Route\n"); if KSR.is_INVITE() and KSR.siputils.has_totag() < 0 then KSR.dbg("EP: ksr_route_relay Base Route\n"); --KSR.sl.send_reply("503", "OLGX Debug"); KSR.setdsturi("sip:192.168.1.14:5060"); --KSR.pv.sets("$du", "sip:192.168.1.12:5062"); end The problem is that Kamailio is dropping the ACK to the 200 OK from the UAS. Wireshark shows that the UAS is retransmitting the 200 OK and the ACK is not being forwarded from the UAC to the UAS.

[ndb_redis] init_without_redis issue
by Denys Pozniak 11 Nov '21

11 Nov '21

Hello! In our architecture, Kamailio uses 2 local Redis servers to get routing information. We noticed that if at the start of Kamailio the first in the modparam list is a running Redis server (name=real), and the second in the list is not running (name=fake), then Kamailio will not even try to connect to the running one. # ----- redis server params ----- modparam("ndb_redis", "init_without_redis", 1) modparam("ndb_redis", "server", "name=real;addr=127.0.0.1;port=6379;db=1") modparam("ndb_redis", "server", "name=fake;addr=127.0.0.1;port=6479;db=2") But if the servers in the list above are reversed, then everything will work as it should. Looks the initialization order affects behavior. Syslog output: Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: ERROR: ndb_redis [redis_client.c:224]: redisc_init(): Failed to create REDIS returned an error: Connection refused Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: ERROR: ndb_redis [redis_client.c:259]: redisc_init(): error communicating with redis server [fake] (127.0.0.1:6479/2): Connection refused Nov 11 18:00:45 kamailio /usr/sbin/kamailio[11445]: WARNING: ndb_redis [redis_client.c:264]: redisc_init(): failed to initialize redis connections, but initializing module anyway.

Forcing Outbound Socket
by Ross McKillop 11 Nov '21

11 Nov '21

Hi All, Try as I may I cannot force an outbound TCP request to use a non-ephemeral source port. Looking at the documentation it seems that as long as I have a line like listen=tcp:10.30.0.55:3339 I should be able to force an outbound connection to originate from that host and port, i.e. to establish a persistent connection from a specific socket to a remote host, but having tried to set it via $fs and set_send_socket() it always uses an ephemeral port. Ideally I would like kamailio to use a specific source port for contacting a specific remote host and keep the TCP socket established, and it seems like it should be simple enough to do but it's not working as expected. Best, Ross

TCP Persistent Connections
by Ross McKillop 10 Nov '21

10 Nov '21

Hopefully the collective hive mind can help with this one, as I have little experience of using TCP in this manner and neither does a friendly Kamailio expert I know personally. I'm replacing a closed box thing that accepts connections from various nodes over TCP. They send INVITEs and REGISTERs over that TCP socket and expect to receive inbound calls over the same established TCP socket. Struggling to make Kamailio behave the same way, but it should be possible. The first time it receives a message, I add the sender to the dispatcher as follows; jsonrpc_exec('{"jsonrpc": "2.0", "method": "dispatcher.add", "params": [5, "sip:$si:$sp;transport=tcp", 0, "socket=tcp:127.0.0.1:5776"], "id": 1}'); This works great, but despite setting the socket to use there, when a call later comes in and it's routed to one of the dispatcher nodes that's been added in this way it fails because Kamailio attempts to open a new connection to the IP / PORT rather than having kept the socket open from the earlier message and reusing the same connection/. Any ideas? I get the feeling I'm missing something obvious! Ross

How to determine size (number of elements) in xavp stack?
by Benoît Panizzon 09 Nov '21

09 Nov '21

Dear Community In my previous post I mentioned my problem with sql_xquery I fear I used this wrong. $dbr is probably only populated if sql_query is used. Anyway, it is always 0 in my testings, even if I clearly get a result. Now I would like to know how many results I have. How can I determine the size of an $xavp stack (or array)? Or is there another way to get the number of rows returned by a sql_xquery without looping an index through all rows? -- Mit freundlichen Grüssen -Benoît Panizzon- @ HomeOffice und normal erreichbar -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

Dear List... kamcmd> version kamailio 5.4.7 (x86_64/linux) Strange issue found. According to: https://kamailio.org/docs/modules/5.4.x/modules/sqlops.html I should get return value 2 if no rows returned: $var(query) contains a query that does not match (number is not assigned) if (sql_xquery("impkam", "$var(query)", "assignedtn") == 1) { if ($avp(debug) > 1) { xlog("L_INFO", "$cfg(route): SQL Dump Result: $var(assignedtn) ROWS: $dbr(assignedtn=>rows) \n"); } do stuff with the assigned number } else { do stuff in case that number is not assigned } Log Output: CHECK_ASSIGNED_TN: SQL Dump Result: 0 ROWS: 0 So the return value of the query was == 1 but the result contains no rows.

STIR/SHAKEN public key
by David Villasmil 05 Nov '21

05 Nov '21

Hello guys, I'm testing with 2 providers right now, and one of them is asking me to include my whole certificate on the *secsipid_add_identity(origTN, destTN, attest, origID, x5u, keyPath)* like: *secsipid_add_identity("$fU", "$rU", "A", "", "https://kamailio.org/stir/$rd/cert.pem <https://kamailio.org/stir/$rd/cert.pem>", "/secsipid/$rd/key.pem");* but it is stated that: *x5u is the HTTP URL referencing to the public key that should be used to verify the signature;* One provider is asking to put the cert there, the other hasn't asked that yet. So i'm a little confused, should the x5u be the actual cert (with its intermediary?) or only the public key? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Is this idea even feasible?
by Antony Stone 04 Nov '21

04 Nov '21

Hi. I'm looking for a solution to the following problem, and wondering whether Kamailio (with which I have very little experience so far) may be it, or whether I'm thinking in totally the wrong direction. The problem: I have a SIP client application which runs on a standard Linux system, and is extremely basic - it can REGISTER in order to receive inbound calls, and it can send INVITEs in order to place outbound calls, and that's about it. It handles media as well - in essence, it's a simple softphone. I can't change it for a more capable one, before anyone suggests that :) Specifically, this thing cannot send REINVITEs in order to put calls on hold, nor can it handle anything to do with transfers (blind or attended). I'm looking for something which does have these SIP capabilities which I could put in between this application and the SIP server through which it is placing and receiving calls, so that I can (through some sort of API) cause calls in progress to be put on hold, resumed, blind transferred, or hold-and-attended- transferred. Does that sound like something Kamailio can do? If so, can anyone point me in a helpful direction re how to go about it? If not, can anyone suggest something else which could sit in between a very basic SIP client and a PBX server, in order to inject these sorts of commands into the path and thereby give me these sorts of extra call capabilities? Thanks, Antony. -- I'm not impossible, just highly implausible. Please reply to the list; please *don't* CC me.

UAC reg_random_delay
by Sergiu Pojoga 03 Nov '21

03 Nov '21

Hi there, May I know what exactly is supposed to be "delayed" in the UAC registration? *modparam("uac", "reg_random_delay", 20)* I have records stored in DB with *reg_delay=0*. When doing *uac.reg_dump*, I do see the value of *reg_delay* being random for various records. However, after restarting Kamailio, the registrations are all sent out *simultaneously*, there doesn't seem to be a "delay", whatever the purpose is supposed to be. Can someone clarify please? Kamailio 5.5.0 Thanks. Regards, --Sergiu

how to prevent the log_prefix in syslog acc cdrs?

Strip VP8 from SDP in rtpengine
by Rahul mm 30 Oct '21

30 Oct '21

Hello, I'm facing trouble with Android 12 using webview to attempt video call. All the media is rotated from rtpengine. To workaround this problem, I wish to strip VP8 and have the calls run on VP9. For this, I added "codec-strip=VP8" but rtpengine is not able to remove it. I've even tried "codec-strip=VP8/90000" but to no avail. The video is still garbled. Am I doing anything wrong here? Thanks and Regards Rahul

Stir/Shaken Kamailio modules - stirshaken vs secsipid
by Joel Serrano 29 Oct '21

29 Oct '21

Hi everyone, As most of us, I'm starting to implement STIR/SHAKEN in our platform. I've seen there are 2 modules available in Kamailio for this: stirshaken: https://www.kamailio.org/docs/modules/5.5.x/modules/stirshaken.html secsipid: https://kamailio.org/docs/modules/5.5.x/modules/secsipid.html Suggestions on which to use? Pros/Cons of each? Do any of you have experience with any of the two? Any comments are more than welcome! Thanks, Joel.

Referring to the expressions outlined at http://www.kamailio.org/wiki/cookbooks/5.4.x/pseudovariables#shtcn_htable_e… , is there any additional documentation or examples floating around that further explains how the right and left prefix matching works?

Configuration script behaviour with http_async_client usage
by Kris Domagalski 29 Oct '21

29 Oct '21

Hi, I'm new in Kamailio and looking for some configuration guidance. I'm using http_async_client for API requests. It's configured to use TEST2 route, which should be executed upon reception of HTTPS response. After receiving the response I would like to go back to the request_route and perform some more actions. Currently behaviour is, in the syslog I can see only entries which I push from TEST2 route (TEST 123). Cannot see the one from request route. Current syslog output: TEST123 Expected syslog output: TEST 123 TEST 789 And now my question is why kamailio is not executing remaining actions (xlog) in request_route? request_route { route(TEST1); xlog("L_INFO","TEST 789\n"); } route[TEST1] { # define API request body in JSON format jansson_set("string", "from", $fU, "$var(http_routing_query)"); # set API request parameters $http_req(all) = $null; $http_req(suspend) = 1; $http_req(timeout) = 100; $http_req(method) = "POST"; $http_req(hdr) = "Content-Type: application/json"; $http_req(body) = $var(http_routing_query); t_newtran(); # send API request http_async_query(http://local:3000/test, "TEST2"); } route[TEST2] { xlog("L_INFO","TEST 123\n"); } Thanks Kris

Re: [SR-Users] No "child_destroy" export - issue with module flatstore and flush=0
by Chaigneau, Nicolas 29 Oct '21

29 Oct '21

Hello Henning, Thanks for your reply ! For the record, I'm using Kamailio module "flatstore" with the flush deactivated. In this situation, when Kamailio is stopped, I'm losing the remaining data in files not yet flushed. So my idea was, when destroy is called, to iterate over the connection pools, and flush/close all the opened files properly. But I found out that it's not that simple :/ Do you think this is something that could be fixed in Kamailio ? Regards, Nicolas.

Hi Nicolas, you are right, there is no special function for children destroy. Most modules do not need it, as the data is in shared memory, processes are started over standard kamailio APIs which will be stopped from the core automatically, to give some background. Some modules do it by just iterating over an internal list of their children and then do the cleanup task. You can find an example in cdp module (destroy, diameter_peer_destroy).

Does failure_route for redirection covers all error cases ?
by Liviu ANDRON 29 Oct '21

29 Oct '21

Hello, We are routing calls to FreeSWITCH servers. We have a failure routing mechanism in place, which looks pretty common from my research around: route[INVITE] { ... t_on_failure("REROUTE"); and failure_route[REROUTE] { if (t_is_canceled()) { exit; } // also 6xx ? if (t_check_status("5[0-9][0-9]") or (t_branch_timeout() and !t_branch_replied())) { // re-route to another available FreeSWITCH server } } The problem is that we don't capture all the failures we would like to, one such example being 480 sent by FreeSWITCH in various cases (even default in hangup_cause_to_sip, mod_sofia.c, https://github.com/signalwire/freeswitch/blob/master/src/mod/endpoints/mod_…), like a Python script crash, but also legitimate cases like "user not registered" (USER_NOT_REGISTERED). Are there other cases? Like a timeout replied (t_branch_timeout() and t_branch_replied()) which never recovers ? Shouldn't any t_branch_timeout() re-arm the failure route ? Thanks, Liviu

t_relay changing source IP?
by Brooks Bridges 27 Oct '21

27 Oct '21

So we have a box that's bound to all interfaces on the server, and one specific IP address (that is an HA IP), and I've run into a bit of an odd behavior that I cannot explain. For 99.9999% of our traffic, the invites come into the HA IP, and then are forwareded out the HA IP to an SBC for further processing. In a very rare instance however, I have found that there is an invite coming in the HA IP, and for some unknown reason it gets forwarded out the *interface* ip instead of the HA IP. For example: Working: 1.2.3.4 -- invite --> 9.8.7.6 (ha IP) -- invite --> 5.6.7.8 (sbc) Non working: 1.2.3.4 -- invite --> 9.8.7.6 (ha IP) *something happens here* 9.8.7.5 (interface IP) -- invite --> 5.6.7.8 (sbc) I've been through tm, tmx, and the incoming invite of a working and non working request with a fine toothed comb and I cannot for the life of me explain this behavior.

Use constants in attrs column of the dispatcher module
by Markus Bönke 27 Oct '21

27 Oct '21

Hello all, I’ve a question regarding the dispatcher module. So far we use on every server a separate database table, where the attribute column is set to the local internal or external socket like "socket=udp:192.168.1.70:5060“ or socket=udp:80.239.xxx.xxx:5060. Is there a way to use constants here like socket=udp:IPADDR_INTERN:5060 or socket=udp:IPADDR_EXTERN:5060 which are replaced when the data is loaded from the DB? Thanks and regards Markus

Kamailio/Asterisk Realtime issues
by Hayden Ryan 26 Oct '21

26 Oct '21

Hi all, I have Kamailio and Asterisk set up in a realtime configuration, like this: https://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb In my setup, Kamailio forwards all REGISTER requests to Asterisk, and Asterisk authenticates them. I have a single peer in sip.conf pointing towards the Kamailio server, as type=peer Each user in the Asterisk database is set to type=user, as when they are set to anything else (or blank), incoming calls from Kamailio to Asterisk display the name of the most recent extension to register. Is there something wrong with my setup here? What I am trying to do is to get MWI working. SUBSCRIBEs for MWI are forwarded to and handled by Asterisk correctly. Yet the MWI state on the handset is incorrect, as I believe it is sending the latest MWI update to the most recently registered extension. Any suggestions would be much appreciated. I assume I'm doing this the wrong way and shouldn't be forwarding any REGISTERs to Asterisk and should be handling authentication in Kamailio itself? But that seems incompatible with the realtime configuration guides I've seen. Thank you, Hayden

Info: risk of failure by upgrading to MariaDB 10.3.31
by Daniel-Constantin Mierla 25 Oct '21

25 Oct '21

Hello, not strictly related to Kamailio, but I know a large number of its deployments run with MariaDB. Be aware of a (pretty high) risk of failure after upgrading MariaDB server to v10.3.31, which comes now on Debian 10 via the usual apt update+upgrade. I was hit on one the servers I upgraded recently, first one worked fine, the 2nd failed to start MariaDB service after upgrade - there is a bug report about it: * https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1823336.h… Downgrading MariaDB seems to be the right solution for now, specially if you didn't do a backup just before upgrade. Don't try other tricks without a fresh backup, data files can be damaged. If you have a fresh backup, there seems to be a solution by deleting database files to start with a clean set and then restore from backup with sql statements. FreeBSD has a similar bug report, so doesn't seem to be only Debian, could be other Linux distros as well. Even with fresh backups, plan for a longer maintenance time frame than usual.

T_req(pv) not accessible in dialog event route in v5.5.2
by Joel Serrano 23 Oct '21

23 Oct '21

Hello, I'm in the process of updating some servers that are running Kam v5.1.4 to v5.5.2. After the upgrade I've noticed that I've lost some custom metrics that we have defined via config-script. Snippet of the relevant config: event_route[dialog:start] { # Gather metrics regarding source IP xlog("L_WARN", "[DLG] - Checking country for ($si | $T_req($si)) - START\n"); if (geoip2_match("$T_req($si)", "src")) { # Country found ... } xlog("L_WARN", "[DLG] - Checking country for ($si | $T_req($si)) - END\n"); } NOTE: xlog lines added for debugging, they normally are not there. In version 5.1.4 in the logs I see: Oct 21 15:55:47 13cn3 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | 186.185.186.7) - START Oct 21 15:55:47 13cn3 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | 186.185.186.7) - END The same config, on v5.5.2 is returning: Oct 21 15:57:08 sbc0504 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | <null>) - START Oct 21 15:57:08 sbc0504 sbc[22606]: WARNING: <script>: [DLG] - Checking country for (A.B.C.D | <null>) - END After enabling debug logs I see: WARNING: <script>: [DLG] - Checking country for (198.1.55.124 | <null>) - START *DEBUG: tmx [t_var.c:309]: pv_get_t_var_req(): used in unsupported route block - type 64*DEBUG: geoip2 [geoip2_pv.c:488]: geoip2_update_pv(): attempt to match: <null> DEBUG: geoip2 [geoip2_pv.c:491]: geoip2_update_pv(): no match for: <null> Did something change in the tmx module that could affect $T_req(pv) being accessible in the dialog:start event_route? Any alternatives to get the source IP of the request (not the reply) in the dialog:start event_route? Let me know if you prefer that I open a ticket for this in GH. Thanks, Joel.

tls connections
by Richard Robson 20 Oct '21

20 Oct '21

I'm trying in vain to get a tls connection to a carrier. ~Without too much detail we are exchanging certificates and they are saying we are triggering a reset of the connection because we are requesting to chage the tcp window size. there are requiring us to have a window size of 65535. there we are sending a smaller window size. as far as I understand this should be OK. I have tried to force out linux install to set the window size to 65535 but we are still sing the smallerwindow in the tcp packet. Is there any settings in Kamailio that could force the window size? we are using Kamailio 5.4.2 Thanks in advance Richard

Catching websocket / TCP errors
by Marrold 20 Oct '21

20 Oct '21

Hi, We're currently implementing WebRTC (SIP over a websocket) on our Kamailio proxies and we're experiencing a minor issue after a restart. We write all USRLOC entries to a shared database to implement HA. These are then loaded on a restart, which leaves us with entries with TCP connections that no longer exist. When a call attempt is made the proxy can't find the connection ID and immediately rejects the call with a "500 No error (2/SL)" - Oct 5 15:38:24 proxy-01 /sbin/kamailio[32087]: WARNING: <core> [core/msg_translator.c:2861]: via_builder(): TCP/TLS connection (id: 0) for WebSocket could not be found Oct 5 15:38:24 proxy-01 /sbin/kamailio[32087]: ERROR: <core> [core/msg_translator.c:2038]: build_req_buf_from_sip_req(): could not create Via header Oct 5 15:38:24 proxy-01 /sbin/kamailio[32087]: ERROR: tm [t_fwd.c:479]: prepare_new_uac(): could not build request Oct 5 15:38:24 proxy-01 /sbin/kamailio[32087]: ERROR: tm [t_fwd.c:1759]: t_forward_nonack(): failure to add branches Oct 5 15:38:24 proxy-01 /sbin/kamailio[32087]: ERROR: sl [sl_funcs.c:414]: sl_reply_error(): stateless error reply used: No error (2/SL) How can we catch this error to avoid terminating the call prematurely?

I did some tests with Docker Compose and it worked fine, but on K8S it does not :-( Here are my logs: Listening on udp: 127.0.0.1:5060 udp: 172.31.4.29:5060 udp: 172.31.0.221:5060 tcp: 127.0.0.1:5060 tcp: 172.31.4.29:5060 tcp: 172.31.0.221:5060 Aliases: tcp: ip-172-31-0-221.eu-central-1.compute.internal:5060 tcp: 172-31-4-29.kube-prometheus-stack-prometheus-node-exporter.infra-prometheus.svc.cluster.local:5060 tcp: localhost4.localdomain4:5060 tcp: localhost4:5060 tcp: localhost.localdomain:5060 tcp: localhost:5060 udp: ip-172-31-0-221.eu-central-1.compute.internal:5060 udp: 172-31-4-29.kube-prometheus-stack-kubelet.kube-system.svc.cluster.local:5060 udp: localhost4.localdomain4:5060 udp: localhost4:5060 udp: localhost.localdomain:5060 udp: localhost:5060 0(1) INFO: <core> [core/tcp_main.c:4983]: init_tcp(): using epoll_lt as the io watch method (auto detected) 0(1) INFO: rr [../outbound/api.h:52]: ob_load_api(): unable to import bind_ob - maybe module is not loaded 0(1) INFO: rr [rr_mod.c:188]: mod_init(): outbound module not available 0(1) INFO: <core> [main.c:3030]: main(): processes (at least): 41 - shm size: 67108864 - pkg size: 8388608 0(1) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 212992 0(1) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 425984 0(1) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 212992 0(1) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 425984 0(1) INFO: <core> [core/udp_server.c:154]: probe_max_receive_buffer(): SO_RCVBUF is initially 212992 0(1) INFO: <core> [core/udp_server.c:206]: probe_max_receive_buffer(): SO_RCVBUF is finally 425984 29(35) INFO: jsonrpcs [jsonrpcs_sock.c:443]: jsonrpc_dgram_process(): a new child 0/35 31(37) INFO: ctl [io_listener.c:213]: io_listen_loop(): io_listen_loop: using epoll_lt io watch method (config) 35(41) INFO: <core> [core/parser/parse_fline.c:147]: parse_first_line(): method not followed by SP 35(41) ERROR: <core> [core/parser/parse_fline.c:271]: parse_first_line(): parse_first_line: bad message (offset: 0) 35(41) ERROR: <core> [core/parser/msg_parser.c:747]: parse_msg(): ERROR: parse_msg: message=<> 35(41) ERROR: <core> [core/receive.c:374]: receive_msg(): core parsing of SIP message failed (194.230.146.66:9055/2) And my service: apiVersion: v1 kind: Service metadata: name: kamailio-tcp annotations: service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: ip service.beta.kubernetes.io/aws-load-balancer-proxy-protocol: '*' service.beta.kubernetes.io/aws-load-balancer-scheme: internet-facing service.beta.kubernetes.io/aws-load-balancer-target-group-attributes: preserve_client_ip.enabled=true service.beta.kubernetes.io/aws-load-balancer-type: external labels: app.kubernetes.io/instance: test-sip app.kubernetes.io/name: kamailio-tcp app.kubernetes.io/version: 5.5.0-buster spec: type: LoadBalancer externalTrafficPolicy: Local ports: - name: sip-tcp nodePort: 30567 port: 5060 protocol: TCP targetPort: 5060 selector: app.kubernetes.io/instance: test-sip app.kubernetes.io/name: kamailio I have a Netwok Load Balancer create with a listener for TCP 5060 but when I try to connect with Zoiper or Linphone, it does not work :-( I used tcpdump on my pod and it received well some SIP commands. Any ideas of what could be wrong here? Thanks in advance! Cedric

Routing dialogs (INVITE) from Lua
by Emilio Panighetti 18 Oct '21

18 Oct '21

Hello, Based on kamailio-basic-kemi.cfg and kamailio-basic-kemi-lua.lua, I’m trying to get a simple test to go through using SIPp built-in UAC and UAS scenarios, using LUA config: Commented out all the registration blocks and trying to run a simple proxy for now, but I can’t seem able to change the URI. SIPp UAC: 192.168.1.12:5060 SIPp UAS: 192.168.1.12:5062 Kamailio 5.5.2: 192.168.15.:5060 Part of the Kamailio.lua config: -- wrapper around tm relay function function ksr_route_relay() -- enable additional event routes for forwarded requests -- - serial forking, RTP relaying handling, a.s.o. if KSR.is_method_in("IBSU") then if KSR.tm.t_is_set("branch_route")<0 then KSR.dbg("EP: ksr_route_relay Set for branch_route\n"); KSR.tm.t_on_branch("ksr_branch_manage"); end end if KSR.is_method_in("ISU") then if KSR.tm.t_is_set("onreply_route")<0 then KSR.dbg("EP: ksr_route_relay Set for onreply_route\n"); KSR.tm.t_on_reply("ksr_onreply_manage"); end end if KSR.is_INVITE() then if KSR.tm.t_is_set("failure_route")<0 then KSR.dbg("EP: ksr_route_relay Set for failure\n"); KSR.tm.t_on_failure("ksr_failure_manage"); end end if KSR.tm.t_relay()<0 then KSR.dbg("EP: ksr_route_relay Set for reply_error\n"); KSR.sl.sl_reply_error(); end -- EP: Base route KSR.dbg("EP: ksr_route_relay Check for Base Route\n"); if KSR.is_INVITE() then KSR.dbg("EP: ksr_route_relay Base Route (DU)\n"); --KSR.sl.send_reply("503", "Debug"); KSR.setdsturi("sip:192.168.1.12:5062"); KSR.pv.sets("$du", "sip:192.168.1.12:5062"); end KSR.dbg("EP: ksr_route_relay exit\n"); KSR.x.exit(); end What’s happening here is that instead of forwarding the INVITE to the SIPp UAC, it creates a loop. Tried KSR.setdsturi() only (KSR.pv.sets commented out) and it’s still the same. If I comment out the 503 reply, then that’s what the UAC gets back. Here’s the log when calling ksr_route_relay: Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/msg_translator.c:162]: check_via_address(): (192.168.1.12, 192.168.1.12, 0) Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:489]: sr_lua_reload_script(): No need to reload [/etc/kamailio/kamaili o.lua] is version 0 Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:673]: app_lua_run_ex(): executing Lua function: [[ksr_onsend_route]] Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:675]: app_lua_run_ex(): lua top index is: 0 Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: tm [t_funcs.c:376]: t_relay_to(): new transaction forwarded Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[0] for: dbg is str: EP: ksr_r oute_relay Check for Base Route Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/kemi.c:85]: sr_kemi_core_dbg(): EP: ksr_route_relay Check for Base Route Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[0] for: dbg is str: EP: ksr_r oute_relay Base Route (DU) Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/kemi.c:85]: sr_kemi_core_dbg(): EP: ksr_route_relay Base Route (DU) Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[0] for: setdsturi is str: sip :192.168.1.12:5062 Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[0] for: sets is str: $du Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[1] for: sets is str: sip:192. 168.1.12:5062 Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/kemi.c:2906]: sr_kemi_pv_sets(): pv set: $du Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/pvapi.c:371]: pv_cache_add(): pvar [$du] added in cache Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1003]: sr_kemi_lua_exec_func_ex(): param[0] for: dbg is str: EP: ksr_r oute_relay exit Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/kemi.c:85]: sr_kemi_core_dbg(): EP: ksr_route_relay exit Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:1837]: sr_kemi_lua_exit(): script exit call Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_api.c:729]: app_lua_run_ex(): ksr error call from Lua: ~~ksr~exit~~ Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: app_lua [app_lua_mod.c:167]: sr_kemi_config_engine_lua(): execution of route type 1 with no n ame returned 1 Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) INFO: LUA {INVITE}: <core> [core/receive.c:515]: receive_msg(): request-route executed in: 1335 usec Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/usr_avp.c:637]: destroy_avp_list(): destroying list (nil) Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/xavp.c:541]: xavp_destroy_list(): destroying xavp list (nil) Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: LUA {INVITE}: <core> [core/receive.c:606]: receive_msg(): cleaning up Oct 17 23:42:48 ol-vm1 kamailio[2416]: 3(2419) DEBUG: <core> [core/udp_server.c:493]: udp_rcv_loop(): received on udp socket: (112/100/661) [[INVITE sip:service@ 192.168.1.15:5060 SIP/2.0 0D 0A Record-Route: <sip:192.168.1.15;lr=on> 0D 0A Via: SIP/2.0/U]] Any idea how we can route this message?

dmq_usrloc writes to database on other nodes too
by Maarten Ureel 17 Oct '21

17 Oct '21

I have the idea that if you enable dmq_usrloc, the other nodes that receive the usrloc info, also try to write to database. We see this by a lot of errors indicating the index violation on postgres. What is the easiest way to tell Kamailio that it does not need to store the usrloc in database if the data came through a DMQ message? Currently I have in my config: # DMQ processing if(is_method("KDMQ") && $Rp == 5090) { dmq_handle_message(); } I have understood that no further processing happens then. So is my assumption correct that my other handling of REGISTER will not be used then? As in, can you handle this in code that it will only store the register information in memory? Like this? # Registration handling route[REGISTRAR] { # If coming from DMQ, don't save to database if(dmq_is_from_node()) { save("location", "0x01") } }

http_async_client "route_name" is considered a failure route?
by Brooks Bridges 16 Oct '21

16 Oct '21

So I've been working on this for a while, and I cannot seem to find a way around this. When using the http_async_client to request data from an external API, the returned data in the "route_name" target is being treated as a failure route, so most of the subsequent processing and messaging that I want to do is not working, either because the function can't be used in a failure route, or because I have to create a transaction prior to doing the request, which then throws an error by immediately triggering a 500 after I return the response I want (via 302 to the requesting client). Am I using http_async_client incorrectly somehow that's causing this behavior or is it expected that the response route is treated as a failure route?

Call to MS Teams
by Володимир Іванець 15 Oct '21

15 Oct '21

Hello all! I'm trying to make a call from the system with Kamailio to a MS Teams. I can answer in the Teams client, system will receive response 200 OK and audio streams will be started. The problem I have is that after a short period of time Teams sends BYE with the reason "An acknowledgement was not received for the call acceptance in the allotted time". If I try to hangup from the system side, Teams will receive BYE and respond with "481 Call Leg/Transaction Does Not Exist" - "Call leg unavailable". It looks like Teams can not match and accept ACK request to finish establishing the call and the following requests have the same problem. I was wondering if someone had this problem before or can share a SIP packet capture (of course with hidden addresses and domain names) of a correctly established and completed call to Teams? Thanks a lot! Regards, Volodymyr Ivanets

unable to receive UDP

After 4 (long) days of trying to receive any UDP SIP, I'm hoping someone can point out what I'm doing wrong. I've looked at the kamailio code. I'm beginning to think it's the 'polling' code, but it looks fine. It could be Centos or a Dell network driver, but not seeing any errors anywhere. - stock build/compile...

Kamailio Inbound proxy to Asterisk - ACL Filtering
by Mihai Cezar 13 Oct '21

13 Oct '21

Hello, I have an issue with filtering on the asterisk side, my requests are: UsersPhones(bria) -> Kamailio -> Asterisk -> Sip Trunk Out. The goal is to manage a new layer of protection ( IP filtering / Whitelisting ). When I try to compile a list of Whitelisted IP in sip.conf I get this error: NOTICE[205]: acl.c:748 ast_apply_acl: SIP contact ACL: Rejecting '145.72.23.45' due to a failure to pass ACL '(BASELINE)' WARNING[205]: chan_sip.c:17061 parse_register_contact: Domain '5.12.16.2:48669' disallowed by contact ACL (violating IP 145.72.23.45) WARNING[205]: chan_sip.c:17933 register_verify: Registration denied because of contact ACL The IP 145.72.23.45, is the proxy kamailio and if I added it to sip.conf it works, but so does every ip afterwards. I tried with contactpermit also with permit, the result is the same as long as I permit the proxy ip it works. Is there something that I can do on the asterisk side to activate this filtering Or there is something that I can do in Kamailio so it will forward the realip ? contactdeny=0.0.0.0/0.0.0.0 contactpermit=145.72.23.45/32 contactpermit=5.12.16.2/32 Thanks in advance,

Hello, I'm wondering if anyone had any issues yesterday with the expiration of the DST Root CA X3 cert? Out of all the servers I manage, only a couple were affected (debian 8). They were production servers so we replaced the cert with a different one to solve the issue while we find the root cause. Anyone out there had any issues yesterday because of this? I'm just curious!

upgrade kamailio 4.4.x-to-5.0.0 - PostgreSQL migrations
by Giovanni Tommasini - timenet srl 11 Oct '21

11 Oct '21

Hi Dears, I'm working on upgrading Kamailio from 4.4.6 to 5.4.0 in an installation where I use PostgreSQL I understand that I have to upgrade in steps by following these links: - http://www.kamailio.org/wiki/install/upgrade/4.4.x-to-5.0.0 - http://www.kamailio.org/wiki/install/upgrade/5.0.x-to-5.1.0 - https://www.kamailio.org/wiki/install/upgrade/5.1.x-to-5.2.0 - https://www.kamailio.org/wiki/install/upgrade/5.2.x-to-5.3.0 - https://www.kamailio.org/wiki/install/upgrade/5.3.x-to-5.4.0 in most of these links, in the section "Database", I find only the subsection "MySQL Database Structure", but I don't find the indications for DB migrations for PostgreSQL Database. Only here https://www.kamailio.org/wiki/install/upgrade/5.2.x-to-5.3.0 I found both the subsection "MySQL Database Structure" and "PostgreSQL Database Structure". What does this mean? - that I'm getting lost in a glass of water? - or that I don't have to make any changes to PostgreSQL? - or that the queries to be launched on PostgreSQL are the same as those for MySQL? I would discard this hypothesis - or that the wiki sections for PostgreSQL are missing? If this were the case, I could proceed with the update and then share the queries I launched to update the wiki. thanks a lot Giovanni Tommasini

Critical log when $mbu pseudovariable is accessed
by Alberto Izquierdo 11 Oct '21

11 Oct '21

Hi, I'm getting some CRITICAL logs when accessing the content of the $mbu pseudovariable in a "onsend_route" function. The log lines look like this: ``` CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:893 FIXME: null send_sock CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:1479 FIXME: null bind_address CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:493 null send socket CRITICAL core 35847:core/msg_translator.c:493 null send socket ``` I've checked the msg_translator.c source file and there are many of `LM_CRIT("FIXME: {message}\n");` calls, and I wonder if the "FIXME" tag relates to the location of the error: a Kamailio error or there is an issue in the user code. Could I have more information about the "FIXME" tag? Thanks in advance!

rtpengine module dependencies
by Juha Heinanen 10 Oct '21

10 Oct '21

rtpengine module README tells this about module dependencies: 3.1. Kamailio Modules The following modules must be loaded before this module: tm module - (optional) if you want to have rtpengine_manage() fully functional Looks like this is not correct. If Kamailio connects to rtpengine over websocket protocol, then there is dependency on lwsc module. I haven't checked if lwsc module works without tls module when wss is used. -- Juha

Kamailio Inbound proxy to Asterisk - ACL Filtering
by Mihai 09 Oct '21

09 Oct '21

Hello, I have an issue with filtering on the asterisk side, my requests are: UsersPhones(bria) -> Kamailio -> Asterisk -> Sip Trunk Out. The goal is to manage a new layer of protection ( IP filtering / Whitelisting ). When I try to compile a list of Whitelisted IP in sip.conf I get this error: NOTICE[205]: acl.c:748 ast_apply_acl: SIP contact ACL: Rejecting '145.72.23.45' due to a failure to pass ACL '(BASELINE)' WARNING[205]: chan_sip.c:17061 parse_register_contact: Domain '5.12.16.2:48669' disallowed by contact ACL (violating IP 145.72.23.45) WARNING[205]: chan_sip.c:17933 register_verify: Registration denied because of contact ACL The IP 145.72.23.45, is the proxy kamailio and if I added it to sip.conf it works, but so does every ip afterwards. I tried with contactpermit also with permit, the result is the same as long as I permit the proxy ip it works. Is there something that I can do on the asterisk side to activate this filtering Or there is something that I can do in Kamailio so it will forward the realip ? contactdeny=0.0.0.0/0.0.0.0 contactpermit=145.72.23.45/32 contactpermit=5.12.16.2/32 Thanks in advance,

update max_while_loops in config
by Juha Heinanen 08 Oct '21

08 Oct '21

It is possible to update value of max_while_loops dynamically in config file? For example, there could be a need to increase the max in some while loop, but after the loop is done, decrease it again for other loops. There exists an rpc command to do that, but I haven't found how to do it in config file. I tried @cfg_seti.core.max_while_loops = 200; but got syntax error. -- Juha

Suspend INVITE between ip4 and ip6 users
by Péter Barabás 08 Oct '21

08 Oct '21

Hi, I try to modify the kamailio configuration to work between ipv4 and ipv6 clients. Clients are mobile sofphones, so they are mostly in background without registration. 1. When an INVITE arrives from IPV4 address, transaction is suspended and a push notification is sent to callee. 2. Callee gets push notification and registers to kamailio. 3. INVITE transaction continues. My kamailio config is based on this article: https://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 using rtpengine. If clients are in foreground it works fine. But, when a client is in background, kamailio knows nothing about the callee’s IP address (ipv4 or ipv6). The problematic case is the call from IPV4 to IPV6. In this case the FLB_V4V6 flag is missing at continue, since in IPV4V6 route it cannot be set and the rtpengine tries the IPV4->IPV4 case. From the other side IPV6->IPV6. It is understandable, since FLB_V4V6 flag is missing in this case. My question is: where and when should I set this flag? Thanks. Peter

Missing line in line.count transformation
by Daniel Donoghue 08 Oct '21

08 Oct '21

I think I’ve found an edge case with the string transformations for line.count: In pv_trans.c, the following code does not appear to consider the last line if there are multiple lines and the last one is not terminated with \n. case TR_LINE_COUNT: n=0; for(i=0; i<val->rs.len; i++) if(val->rs.s[i]=='\n') n++; if(n==0 && val->rs.len>0) n = 1; val->flags = PV_TYPE_INT|PV_VAL_INT|PV_VAL_STR; val->ri = n; val->rs.s = int2str(val->ri, &val->rs.len); break; This means that my count is always one off unless I force a blank line at the end of my string. Also, this code does not cater for cases where there is a different line terminator, such as CR or CRLF as is the case when the string comes from a Mac or windows system, respectively; it might be useful to have a transformation for doing that as I’ve had to hack it using s.replace with hexadecimal escape codes (\r and \n do not work) in a variable. With every blessing, — Daniel Donoghue

Parsing Error in Timer Module of kamailio
by Surabhi Garg 07 Oct '21

07 Oct '21

Hi Team, Greetings! I am trying to use Timer Module of Kamailio to keep calling particular route at particular time interval. Here is the snippet of my config: loadmodule "timer.so" modparam("timer", "declare_timer", "MYTIMER=SHUTDOWN,5000,slow,enable"); route[SHUTDOWN] { xlog("system shutdown: $sht(graceful_shutdown=>shutdown)\n"); } But after restarting the Kamailio, I keep on getting parsing errors in every 5 sec and my route "SHUTDOWN" never get called. Which means timer is getting called in every 5 sec but not able to call the route. Could you please help me with this why these parsing errors coming? am I missing some arguments here? Kamailio Version: 5.5.X. Errors: Sep 23 15:29:31 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<GET /timer HTTP/0.9#012#012> Sep 23 15:29:31 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: timer [timer.c:204]: timer_handler(): parse msg failed Sep 23 15:29:36 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<GET /timer HTTP/0.9#012#012> Sep 23 15:29:36 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: timer [timer.c:204]: timer_handler(): parse msg failed Also, in place of timer module I tried using rtimer module as well which is also giving me similar results as per my requirement. But Could you please help me with the pros and cons of both the modules timer and rtimer. Any thoughts on this would be appreciated Surabhi Garg Mobile - 91 783 888 7523

[kamailio/kamailio] SIP Preconditions Settings?
by Luis Joel Borrego Soto 07 Oct '21

07 Oct '21

Hi Team, According with the RFC3312 (https://datatracker.ietf.org/doc/html/rfc3312) The SDP parameters are the following We define the following media level SDP attributes: current-status = "a=curr:" precondition-type SP status-type SP direction-tag desired-status = "a=des:" precondition-type SP strength-tag SP status-type SP direction-tag confirm-status = "a=conf:" precondition-type SP status-type SP direction-tag **precondition-type = "qos" | token strength-tag = ("mandatory" | "optional" | "none" = | "failure" | "unknown")** status-type = ("e2e" | "local" | "remote") direction-tag = ("none" | "send" | "recv" | "sendrecv") Which one should be the equivalent in the Kamailio?, is the a specific module?

Need kamailio to use advertise public IP only in cases of SIP communication over internet.
by Voip support 06 Oct '21

06 Oct '21

Dear Community, I have a need of communicating with other servers using private IP with private IP in Via and SDP connection information but at same time sometime need connect to public IP SIP server and on outgoing INVITE's i need advertise public IP in Record-Route and SDP Connection information. Currently if i work on listen=udp:privateip:5060 i get working the LAN part but cannot work over internet (no audio) but when i add advertise i get SDP public IP also over local network. Is it possible to solve this case using one NIC adapter? I am using RTPProxy. Please help me out. I tried to add second network adapter with advertise and mhomed=1 something started to work but i think i would need work on the call direction and different rtpproxy_manage handling on outside INVITEs and incoming 200 OK responses. I am not sure if this is the right way to do it - maybe there is some easier method of achieving what i need using one interface ? Best regards, Tom

Understanding regex format for subst_hf
by Joel Serrano 06 Oct '21

06 Oct '21

Hey guys, I'm trying to do a replacement regex using subst_hf but I can't seem to get the format right and the docs are confusing. *subst_hf: *docs say it uses perl-like regex (as I understand it, that would mean PCRE). Docs also say in the 'subexp' param that it uses the same format as *subst.* *subst: *at the beginning it says it uses perl or sed format, but in the '/re/repl/flags' param it says that sed format. https://www.kamailio.org/docs/modules/devel/modules/textops.html#textops.f.… 4.20. subst_hf(hf, subexp, flags) Perl-like substitutions in the body of a header field. Meaning of the parameters is as follows: - *hf* - header field name. - *subexp* - substitution expression in the same format as of the 'subst' function parameter. - *flags* - control flags - it has to be one of: a - all headers matching the name; f - only first header matching the name; l - only the last header matching the name. 4.16. subst('/re/repl/flags') Replaces re with repl (sed or perl like). Meaning of the parameters is as follows: - *'/re/repl/flags'* - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line). 're' - is regular expression 'repl' - is replacement string - may contain pseudo-variables 'flags' - substitution flags (i - ignore case, g - global) I'm trying to use this: subst_hf("X-myheader", "/^(?!string1 |example2-|text3 )(.*)/myprefix \1/", "a") In an online tester using PCRE, the format is correct, but Kamailio doesn't like it: Oct 4 09:29:16 cops-n1 cops[15957]: ERROR: <core> [core/re.c:285]: subst_parser(): bad regular expression ^(?!string1 |example2-|text3 )(.*) in /^(?!string1 |example2-|text3 )(.*)/myprefix \1/ If I remove the negative lookahead chars (?!) then kamailio doesn't complain but the regex doesn't do what I want. Does this mean that Kamailio won't support negative lookahead for subst regex replacements? What I'm trying to achieve is something along: "If the value of the header Myheader doesn't start with ABC, DEF or HIJ, then prefix it with XYZ" Any suggestions/ideas on how to achieve this? Thanks, Joel.

Kamailio/RTPengine as a proxy for FreePBX/Asterisk...
by Micah Quinn 03 Oct '21

03 Oct '21

Hello all, I'm new to Kamailio, so bear with me as I stumble through this. First, I'll describe what I'm trying to achieve at a high level and then perhaps somebody can advise me on whether Kamailio is a good fit for this solution or not. I'd like to be able to deploy a small appliance type server to our customer's sites that just runs Kamailio and a VPN connection back to our datacenter. At our datacenter, we run virtualized instances of Asterisk for each of our customers. The idea is that Kamailio would act as a transparent proxy through to the Asterisk instance under nominal conditions and as a basic SIP router in the case that the Asterisk instance is unavailable. This degraded functionality would then at least allow extension to extension calling even if the Internet or Asterisk instance is down. I'm currently using dispatcher with a single entry in preparation for a time when we might want to failover to another Asterisk instance. I'm forwarding all REGISTER and INVITE messages to the server chosen from ds_select_dst. Initially this all seems to work as I can register with a softphone and pjsip show endpoints shows my softphone connected. However, when I attempt to call any extension (my own or another) Asterisk responds to the INVITE message with a "401 Unauthorized" message and the typical "The person at extension XXXX is unavailable...". I know that more details might be necessary to troubleshoot this, but I didn't want to include everything in one post and risk cluttering it up with unnecessary information. If anyone can confirm that this is a reasonable way to approach the problem, I can then provide whatever relevant data is necessary to get deeper into it. (I've used sngrep, logging, asterisk cli, etc.) Thanks in advance for any help.

ACK not accepted

Hi, I am having a problem with some inbound calls that all have the below behavior. My setup has: Carrier(UDP) -> (UDP)Kamailio1(UDP) -> (UDP)Kamailio2(TLS) -> (TLS)UAC Kamailio1 has Topos Module. UAC is behind NAT with LAN IP 192.168.1.105 and Public 200.200.200.30 Carrier IP 50.50.50.19, Kamailio1 IP 100.100.100.243, Kamailio2 IP 100.100.100.210 The Carrier sends in a new call and the call is answered from the UAC with 200 OK SDP. Carrier sends ACK and it looks like it reaches the UAC but, UAC still resends several times 200 OK and carrier sends server ACK that arrives or not ??? to UAC until finally UAC sends a BYE. On the SIP flow you can see that Kamailio2 sends the ACK to 192.168.1.105 and not to 200.200.200.30. Is this ok?? Another thing to mention is that Kamailio2 that has the UAC connected via TLS, can be used fine from the UAC to make an outbound call following the reverse path, but on the inbound we have the below. Any help will be much appreciated, ACK from Kamailio2 100.100.100.210 to UAC Session Initiation Protocol (ACK) Request-Line: ACK sip:btpsh-f3-6153392a-5fa-5@192.168.1.105:5061;transport=TLS SIP/2.0

Querying presence state from config file
by Igor Olhovskiy 01 Oct '21

01 Oct '21

Hello! Is there any method of querying presence (dialog) state for particular endpoint from config file other than that direct query to presence tables in database? Idea is to reflect server-side DND state as "confirmed" (talking) , so I need to skip certain PUBLISH messages not to reset this state. -- Best regards, Igor

kamailio 4.4 + RTPPROXY - virtualbox - setup - callee or caller sends INVITE during the conversation and at REGISTER EXPIRES stop the connection
by Youssef Boujraf 01 Oct '21

01 Oct '21

Dear Thanks for your quick reply and sorry for spamming your mailbox. I am very confused about the setup of kamailio.cfg and rtpproxy. I have an existing kamailio 4.4 - rtpproxy running and I get the config files from both and setup the new vm. Just private connection works but the idea is to have connection from outside too. I am sure there is a mismatch with public ip, natting and/or setup of the vm hosts file. - architecture: *- 1x virtualbox* + 1x vm with bridge mode for network (get private ip address from the router). I suppose this is the PRIVATE_IP *+ 1x desktop (windows)* hosting a sipphone here Microsip ( https://www.microsip.org/) *- 1x modem/router* from the telecom provider - bbox-3V+ from PROXIMUS + forced in DMZ host the Kamailio server PRIVATE_IP [image: 211001 - kamailio architecture and settings.png] - the hosts file from Kamailio + rtpproxy is ( Maybe something is wrong or missing) /etc/hosts 127.0.0.1 localhost > 127.0.1.1 sipsecure.by-systems.be sipsecure > 192.168.1.19 sipsecure.by-systems.be sipsecure > xxx.XXX.xxx.XXX sipsecure.by-systems.be sipsecure > # The following lines are desirable for IPv6 capable hosts > ::1 localhost ip6-localhost ip6-loopback > ff02::1 ip6-allnodes > ff02::2 ip6-allrouters > */etc/kamailio/kamailio.cfg* kamailio.config > #!define PUBLIC_IP "xxx.xxx.xxx.xxx" > #!define PRIVATE_IP "192.168.1.19" > #!define PRIVATE_NET "192.168.1.0/24“ > > #!ifdef WITH_NAT > > # ----- rtpproxy params ----- > > modparam("rtpproxy", "rtpproxy_sock", "udp:PRIVATE_IP:7722") > > > # ----- nathelper params ----- > > modparam("nathelper", "natping_interval", 30) > > modparam("nathelper", "ping_nated_only", 1) > > modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) > > modparam("nathelper", "sipping_from", "sip:pinger@kamailio.org") > *Etc/default/rtpproxy* PRIVATE_IP=192.168.1.19 > > PUBLIC_IP=xxx.xxx.xxx.xxx > > rtpport_min= 10000 > > rtpport_max=20000 > > syslog=DBUG:LOG_LOCAL5 > > #Defaults for rtpproxy > #The control socket. > #CONTROL_SOCK="unix:/var/run/rtpproxy/rtpproxy.sock" > #To listen on an UDP socket, uncomment this line: > #CONTROL_SOCK=udp:127.0.0.1:7722 > #Additional options that are passed to the daemon. > EXTRA_OPTS="-l $PRIVATE_IP/$PUBLIC_IP ="-s $PRIVATE_IP:7222 -m $ > rtpport_min -M $rtpport_max -d $syslog"` > - *Misconfiguring the VM* That means do I need to use setup 1 or 2 or another 1. 2x NIC interfaces (one with private ip, second from dmz ip + NAT1:1 public ip) 2. 1x NIC interface (one private ip and natted 1:1 with public address) - *test* 1. *use case 1 : *connect two (2x) sipphone from private network (included kamailio) = OK 2. *use case 2 :* connect one (1x) codec from private ip and one (1x) codec from public network (like mobile) = = issue - disconnect after 30 s (register expires) start a conversation with audio but the caller or the callee continues to send and INVITE message. 3. *use case 3 :* connect two (2x) sipphone from public network = issue - disconnect after 30 s (register expires) start a conversation with audio but the caller or the callee continue to send an INVITE message.

RTPEngine + Kamailio state question
by Alex Balashov 30 Sep '21

30 Sep '21

Hi, Sorry if I missed any developments on this, but: Kamailio does keep a runtime association of Call-ID+Ftag => RTPEngine instance, which is significant if an RTPEngine set with multiple members is used, or if a non-default set is used for a given call. When Kamailio is restarted, this runtime association goes away, so any subsequent offer/answer cycles or any other commands will (maybe) go to the wrong RTPEngine and/or the wrong set. Last time I checked a few years ago, there was no way to persist this association across restarts. Has this changed?

Sipwise SEMS
by David Villasmil 30 Sep '21

Hello guys, I know SEMS can provide conference, voicemail, and other services. In theory it’s also a B2BUA. Could I use a python script to provide a simple routing service? I.e.: receive an invite and send it somewhere else based on some routing logic? Thanks all David -- Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

using LDAP as database ?
by Volker Denneberg 28 Sep '21

28 Sep '21

Hi, I am searching for a setup where phones register at a central kamailio and kamailio shares these contact infos with multiple asterisks. So they all need to share a database. For redundancy reasons, the database should work across 2 datacenters. As far as 1 understood there are some options * use mysql - good chances to find example code, Siremis API, seems to be the standard solution * use redis - more performant than mysql * use ldap - good chances to integrate with existing IT management but most difficult to configure Maybe I missed a better approach? Kamailio's ldap driver (http://www.kamailio.net/docs/modules/5.3.x/modules/db2_ldap.html) seems to be from 2008 - is it still recommended ? Kind regards, Volker

We have added Homer 7 latest version to consolidate traces from all kamailios and we have enabled siptrace module on kamailio to send data to homer. What we have seen up today is that traces on homer have sip headers before topos changes. So if I look at the same call on sngrep on the kamailio machine, I see the correct topos changed headers. If I check the same call on Homer I see headers without topos changes. Also we get duplicate headers on ACKs on homer. I was wondering what we have done wrong in the config and we have these results on homer. Any help will be much appreciated! Our config has: ===========- #!substdef "!MY_HOMER_CAPTURE!sip:MY_HOMER_IP_ADDR:MY_HOMER_PORT!g" #!substdef "!MY_LOCAL_SENDSOCK!sip:MY_KAMAILIO_IP:MY_LOCAL_SEND_PORT!g" loadmodule "topos.so" loadmodule "siptrace.so" modparam("siptrace", "force_send_sock", "MY_LOCAL_SENDSOCK") modparam("siptrace", "duplicate_uri", "MY_HOMER_CAPTURE") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 0) modparam("siptrace", "hep_capture_id", NODE_ID) modparam("topos", "db_url", DBURL) modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "branch_expire", 130) # 3 Min modparam("topos", "dialog_expire", 10800) # 3 Hours modparam("topos", "clean_interval", 60) modparam("topos", "event_mode", 3) request_route { sip_trace_mode("t"); ........ } onsend_route { if (is_method("ACK")) { sip_trace(); } } ============== Thank you! Kind regards, Angelo

Hello, a new server is available to offer APT repositories for each released version of Kamailio: * https://deb-archive.kamailio.org/ It aims to offer a way to downgrade to an older version, if someone wants it for various reasons. At this moment it offers dedicated APT repositories for Kamailio 5.3.8, 5.4.6, 5.4.7, 5.5.1 and 5.5.2. More details were posted in a news article at: * https://www.kamailio.org/w/2021/09/apt-debian-packages-archive/ Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - Online Nov 08-11, 2021 (Europe Timezone) - Nov 22-25, 2021 (America Timezone) * https://www.asipto.com/sw/kamailio-advanced-training-online/

PRACK with UDP to TCP translation send over wrong protocol
by Angelo Sipper 24 Sep '21

24 Sep '21

Hello, We have the following setup and I am having trouble passing the PRACK with correct protocol to the provider. UAC (OverTLS) ->(UDP)Kamailio1 (UDP)-> (UDP)Kamailio2 (TCP)-> (TCP)Provider UAC : 10.2.1.160 NATED to 100.100.100.61 <http://50.50.50.50:5065/> (TLS) Kamailio1 Sockets: 50.50.50.210:5061 <http://170.170.170.210:5061/> (TLS), 50.50.50.210:5060 <http://170.170.170.210:5060/> (UDP) Kamailio2 Sockets: 50.50.50.182:5060 <http://170.170.170.170:5060/> (UDP) 50.50.50.182:5080 <http://170.170.170.170:5060/> (TCP) Provider: 200.200.200.209:5060 <http://200.200.200.193:5060/> (TCP) We use dispatcher on Kamailio1 & Kamailio2 The invite goes fine from UCA up to the provider and the provider responses arrive to UAC fine. The PRACK from UAC to kamailio1 goes fine to Kamaili02 but, Kamailio2 uses the UDP socket to send to the provider so the PRACK does not arrive to the provider and the call is canceled. If the provider is on UDP everything works fine. Below I have the trace. What should I look for in the config to resolve this wrong protocol/socket on the PRACK?

Releasing Kamailio 5.3.9
by Henning Westerholt 23 Sep '21

23 Sep '21

Hello, I am planning to release in two weeks (likely on Wednesday 7th October) the next minor version out of branch 5.3, version 5.3.9. Backports of fixed issues from other stable branches will be integrated as usual. If you are aware of new issues which were not yet reported on the issue tracker or are missing back-ports, report them. Please note that this will be the last minor release created from the 5.3.x stable branch. The stable branches are usually maintained from the Kamailio development team for a period of two years. The other two stable branches of Kamailio will still be maintained (5.4.x and 5.5.x). Cheers, Henning -- Henning Westerholt - https://skalatan.de/blog/ Kamailio services - https://gilawa.com<https://gilawa.com/>

Re: [SR-Users] How to get $fU and $tU from MSRP module?
by Henning Westerholt 22 Sep '21

22 Sep '21

(please keep the list in CC) Hello, I see – its kind of pseudo-SIP message that is presented in the cfg in this route. And it seems that you want to access the cpim body. You already checked that the $msrp(crhop), $msrp(nexthop) and $msrp(prevop) etc.. are not working for you? It’s probably not the best way, but what about using $msrp(body) to get the body and then using a regular expression (like a transformation) on this to get the From/To?

Hi, I have a question regarding the jsonRPC commands in the siremis GUI. 【Environment】・Centos7 ・Kamailio 5.5.2 ・siremis 5.3 (installed by git clone https://github.com/asipto/siremis siremis-5.3.x) ・php php-mysqlnd-7.1.33-16.el7.remi.x86_64 php-json-7.1.33-16.el7.remi.x86_64 php-mbstring-7.1.33-16.el7.remi.x86_64 php-pdo-7.1.33-16.el7.remi.x86_64 php-gd-7.1.33-16.el7.remi.x86_64 php-xml-7.1.33-16.el7.remi.x86_64 php-pecl-zip-1.19.4-1.el7.remi.7.1.x86_64 php-xmlrpc-7.1.33-16.el7.remi.x86_64 php-cli-7.1.33-16.el7.remi.x86_64 php-process-7.1.33-16.el7.remi.x86_64 php-pear-1.10.13-1.el7.remi.noarch php-common-7.1.33-16.el7.remi.x86_64 php-7.1.33-16.el7.remi.x86_64 When I execute commands in command service →JSONRPC commands from siremis GUI, it always shows error page. I tried some approaches <https://eow.alc.co.jp/search?q=approaches&ref=awlj> referring to this page, https://github.com/asipto/siremis/issues/26 but I still have this error message in /var/log/httpd/error_log > [Tue Sep 21 16:43:26.396967 2021] [php7:warn] [pid 6181] [client > 152.165.116.138:55822] PHP Warning: strstr() expects parameter 1 to be > string, resource given in > /var/www/siremis-5.3.x/openbiz/bin/ErrorHandler.php on line 158, referer: > http://kamailio.xcallyjp.com/siremis/sipadmin/jrcmds > [Tue Sep 21 16:43:26.401139 2021] [php7:notice] [pid 6181] [client > 152.165.116.138:55822] u socket send failed: Permission denied, referer: > http://kamailio.xcallyjp.com/siremis/sipadmin/jrcmds I have tried my best to do some researches about it, but still stuck.

Question regarding parser error for REGISTER request
by Floimair Florian 20 Sep '21

20 Sep '21

Hello List! We have a certain user agent that somehow triggers a parser error log entry, everytime this type of user agent registers. Sep 20 12:03:49 kamailio-dev-1 /usr/sbin/kamailio[1803]: ERROR: <core> [core/parser/parse_param.c:517]: parse_param2(): Invalid character, ; expected The odd thing now is that this register still succeeds. And we do not see that error for other methods like e.g. INVITE. The user agent in question is an Android app based on linphone which we develop inhouse. We also use the same for iOS where the error does not occur. The REGISTER request contains a push-token in the Contact header and I think this is where the parser somehow generates this error. Since this is the only line apart from the User-Agent header where the content of the two is different. We did have a look and diffed the differences between our iOS and Android app variants and didn’t see any obvious problem or invalid character (compared even with hex editor). So my questions regarding this I hope that someone of you can help me with: * Is there any way to make the parser error more verbose (e.g. which character in which header it is complaining about)? Right now it only says that there was an error and that it expected ‘;’ but not where and what character was found instead. * Why does the parser throw the error but the registration still succeeds? It does not quite make sense to me.

Question on the SL Module
by Alessio Garzi 20 Sep '21

20 Sep '21

Hello Kama ML, today I stumbled on function "update_sl_stats()" inside sl_stats.c and noticed that some response codes are treated differently. For example here: https://github.com/kamailio/kamailio/blob/a9ef78b7f43616f2ceaa26df97eff68eb… since we have a "break;" statement, when a 500 code is received, the 5XX counter is not incremented even if a 500 code belongs to the 5XX family. We have the same behaviour for other response codes and it really seems that it's not a bug and the author really wanted it. The docs are not so helpful and they don't explain much in detail how counters are built. I just want to have confirmation this is how it must work and I wonder if it's the case to write something about it into the docs. Thanks Alessio

Kamailio - FreeSWITCH - RTPproxy
by Jerry Kendall 20 Sep '21

20 Sep '21

Hello all, I am new to the list but have been reading plenty. Loads of good tips and help. I am playing with Freeswitch and would like to put Kamailio/RTPProxy in front for the user endpoints. Freeswitch will talk directly with the service provider. I am wondering *if* i can do this... 1) have the endpoints register with kamailio 2) have the media proxy via RTPProxy as it is needed for NAT 3) have the actual work (voicemail/ring groups/ivr/conference/etc...) done on Freeswitch 4) have all the SUBSCRIBE/PUBLISH/PRESENCE done on Kamailio Is this doable? Are there any guides to setting this sort of thing up? regards, Jerry

Reinite breaks the call
by Angelo Sipper 20 Sep '21

20 Sep '21

Hello, I am trying to understand a problem we have with reinvites. When there is a reinvite on the call our provider refuses to receive the reinvite and the call is dropped. The setup is the bellow: UA-> Kamailio1 -> Kamailio2 -> Provider On Kamailio2 we have Topos enabled. Looking on the trace I can see that on the second invite, Kamailio does send out the original contact and not the one that was originally send out to the provider. Is this correct? Is this breaking the call? Bellow the trace and the flow from Kamailio2 until the second reinvite. All reinvites are the same as per the last Thank you for your help! 2021/09/15 16:29:59.420162 50.50.50.181:5060 -> 200.200.200.193:5060 INVITE sip:1234567890@sip.mydomain.com:5060 SIP/2.0 Via:

hello Ben I was using development functions and the C code of this function did not exist. I needed to manually add a contact to kamailio but this does not work and I used the HTable module to solve the problem. Thanks for the tips

BLF when phone boots up
by Jerry Kendall 17 Sep '21

17 Sep '21

Hi, I have looked at lots of postings but can't seem to find the answer I seek. I have 6 phones (Grandstream GXP2170, etc) connected to Kamailio 5.2.1 running default config file with changes per https://kb.asipto.com/kamailio:presence:k43-blf On x301, I have the 3 BLFs setup to monitor x302, x303 and x304. If I dial 303 from 301, the BLFs work (flash, red, then green) as expected. But, when the phone initially boots up, the BLFs are all dead - until the first PUBLISH event. So, the question is, how do I get the BLFs to become valid and with the correct status when the phone boots up??? regards, Jerry

listen directive during runtime
by Tihomir Culjaga 17 Sep '21

17 Sep '21

Hi, is it possible to add a listen directive during kamailio runtime ? The reason I'm asking this is in a situation when I add a new peering trunk (from a different network segment), I need to add a network interface to the kamailio server and then add a specific listen directive for that interface to reference the socket by name. listen=udp:10.1.1.11 name "mySN1" so i can further reference to a specific socket name when routing SIP messages. Please advise, Regards, Tihomir.

problem with LRKProxy module
by hamed r 16 Sep '21

16 Sep '21

Hello I have problem with lrkproxy module. First, I installed the packages from the link below : https://github.com/mojtabaesfandiari/pylrkproxy And the service was properly listened to the local ip (192.168.51.106:22333 ). In the next step, the parameters were added to the kamalio.cfg file : loadmodule "lrkproxy.so" modparam("lrkproxy", "lrkproxy_sock", "udp:192.168.51.106:22333") I also changed the /etc/pylrkproxy/pylrkproxy.ini to set local ip. But when I make a call, the ip inside the sdp not change. And the following error is displayed in the syslog: Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: INFO: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1507]: lrkproxy_force(): Here is SIP_REQUEST & METHOD_INVITE Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: ERROR: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1084]: select_lrkp_node(): script error -no valid set selected Sep 4 07:18:05 debian /usr/local/sbin/kamailio[1724]: ERROR: {1 2 INVITE NzA0NmU0YTYwNWNkNzAwOWJiOTUyOWQ5ODhjNjRhNzk.} lrkproxy [lrkproxy.c:1513]: lrkproxy_force(): can't ping any lrk proxy right now.

DMQ module issues
by Zé Santos 16 Sep '21

16 Sep '21

Hi guys, I am currently using kamailio v5.2.5 and running it inside a container. I already attempted to upgrade the kamailio to the latest version however the problem persists. This is the core dump that I got from using gdb: Core was generated by `/usr/sbin/kamailio -f > /etc/kazoo/kamailio/kamailio.cfg -m 512 -M 64 -x tlsf -w'. > Program terminated with signal 11, Segmentation fault. > #0 0x000000000071c63c in select_cfg_var (res=0x7ffd57d49b10, > s=0x7f2649395040, msg=0x7ffd57d4c340) at core/cfg/cfg_select.c:211 > 211 i = *(int *)p; It seems that the problem is with this line: modparam("dmq", "notification_address", "sip:DMQ_NOTIFY_ADDRESS") > Also, I only have this issue while running on an AWS instance, I have the same setup on my local computer, however kamailio is able to start correctly. While kamailio is starting, I have this line #!substdef "!DMQ_NOTIFY_ADDRESS!10.10.10.10:5090!g" It seems that after DMQ is able to obtain the IP address, when it comes to actually sending the message, it is interpreting the ip address of the DMQ_NOTIFY_ADDRESS as an integer and then it gives out a segmentation fault and the module stops. Another interesting thing is that if the DMQ_NOTIFY_ADDRESS is the MY_IP_ADDRESS variable instead of the 10.10.10.10, it seems to work properly. #!substdef "!DMQ_NOTIFY_ADDRESS!MY_IP_ADDRESS:5090!g" It also doesn't seem related to the ip being in a variable, since I already tried using a DNS record, and once again, it is able to obtain the IPs from the DNS record, and the same issue applies. Has anyone ever seen anything like this? I can't find any evidence of this actually happening. Thank you kindly for your time. Best Regards, José Santos

Best practice for Kamailio "cluster" front for many TLS connections
by Angelo Sipper 15 Sep '21

15 Sep '21

Hello, We are thinking to use kamailio to fully support our current voip service. I would like to know what is the best practice to use kamailio for several thousands for clients that connect to us via TLS. We would like to have a front "cluster" to be able to handle all these connections in balanced way. All clients register to us and the do calls that we statefully forward to the provider. On our test we have already created a single kamailio that successfully accepts and handles registration, do the control and routing to next provider with dispatcher and also do the accounting with cdrs. We want to separate this controlling, routing, accounting and dispatching from the front end and create a front "cluster" to offload the TLS and also be redundant to as many connections by adding more kamailio's. What would be the best kamailio module and topology as solution to this requirement? Thank you in advance. Kind Regards, Angelo

Fwd: Catching an overall timeout after dropping replies
by Marrold 15 Sep '21

15 Sep '21

Hi, This is partially related to a previous thread - https://lists.kamailio.org/pipermail/sr-users/2021-August/113128.html We are using the TSILO module to suspend transactions whilst we wait for mobile app users to register after receiving a push notification. In the time we are waiting for the app to register, other UAs might reject the call (DND, Busy, etc). To avoid this failure response being relayed to the caller, we use t_drop_replies in the failure_route. Eventually if all devices have rejected the call Kamailio times out and sends a 408 Request Timeout. Is there any way we can catch this error, and replace it with the last response we got from an actual UA? t_is_expired() and t_branch_timeout() don't seem to apply as they're on the *called* side. Is there another option to catch this overall timeout? As a side note, failure_route is quite limited in the actions that can take place there. Is it safe to access variables and update a htable? Thanks Matthew

Re: [SR-Users] Empty Subnets in Permissions Module
by Henning Westerholt 14 Sep '21

14 Sep '21

Hello, please keep the list in CC. Let’s look into the two issues one by one: 1) I had to explicitly configure the parameter: modparam("permissions", "mask_col", "mask") Although the documentation suggests "mask" is the default - the JSON output from "kamctl address dump" did not output this value on K5.5. (On K5.3 it outputted properly) Do you get an error if you do not specify the mask_col like this, or something else? From the source code the default should be “mask”. When I run the "kamcmd permissions.subnetDump" on Kamailio 5.3, it returns everything as expected - including the 0.0.0.0/0<http://0.0.0.0/0> subnets. However, when running the same commands on Kamailio 5.5, it only returns a small subset (of only 20) subnets/groups - and the selection does not appear to follow a logical selection criteria. Additionally, it does not return any groups with a 0.0.0.0/0<http://0.0.0.0/0> subnet either. It seems that the behaviour has changed regarding the “0” subnet, checkout the docs: https://kamailio.org/docs/modules/devel/modules/permissions.html#permission… It will convert them to 32/128 respectively. Can you see a 0.0.0./32 in your dump? This was changed in commit f376c82a9f8 during an extension for text files. Maybe Daniel can comment here if this was done by purpose. Otherwise, you can open an issue on our tracker about it.

Capturing response from uac_reg module
by Ross McKillop 14 Sep '21

14 Sep '21

Hi, What's the best way to capture the response from REGISTER requests automatically initiated by the uac_reg module? I was looking to use event_route[uac:reply] {} but that is only triggered if the evroute flag is set on the initial call made to uac_req_send() Is there a way to set this globally so that uac:reply is called for all requests initiated for peers in the uacreg table or a better way to capture the response? Best, Ross

Manage blacklisting on network errors
by Marat Gareev 14 Sep '21

14 Sep '21

Hello! I have a simple config for routing requests with failover and blacklisting on 408, 480 and 503 codes from servers. This is a part of config: # Wrapper for relaying requests route[RELAY] { # the base event routes t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); t_on_failure("MANAGE_FAILURE"); if (!t_relay()) { sl_reply_error(); } exit; } # Manage incoming replies onreply_route[MANAGE_REPLY] { xlog("L_NOTICE", "$rr ($rs) [$cs] ($ci) $si:$sp - $ua\n"); if ( t_check_status("(503)|(408)|(480)") ) { xlog("L_WARN", "Server will be blacklisted: $si:$sp ($rs)\n"); } } # Manage failure routing cases failure_route[MANAGE_FAILURE] { if ( !t_check_status("(503)|(408)|(480)") ) { exit; } ds_mark_dst("IP"); # blacklist if (t_is_canceled()) exit; if (!ds_next_domain()) { send_reply("503", "Service Unavailable"); exit; } route(RELAY); } If there is a timeout or network error on the server side, it is blacklisted. How can such cases be managed and how can they be logged? I didn't find this on the module page: https://www.kamailio.org/docs/modules/stable/modules/tm.html

Question about suspected memory leak presence module
by Albert Petit 14 Sep '21

14 Sep '21

Hi, I am suspecitng presence module might be having a memory leak on a production server used by an end user (not have access to it). The output of command kamcmd mod.stats presence shm is Module: presence { mem_copy_subs(148): 25720 mem_copy_subs_noc(214): 1672201904 mem_copy_subs_noc(251): 678406560 add_event(181): 88 shm_copy_event(57): 40 shm_copy_event(50): 312 add_event(156): 40 add_event(149): 456 new_shtable(66): 5767168 new_shtable(53): 262144 init_evlist(289): 16 Total: -1938302848 } I am not sure what mem_copy_subs_noc is meaning. And final output is negative, SHM is incfreasing all the time but not sure of the root cause is this a reasonable hint that a memory leak is related to presence?

Kamailio dispatcher -> FreeSWITCH transfers handling.
by Тимур Ситдиков 11 Sep '21

11 Sep '21

Hi list! :-) I'm a total newbie in Kamailio. Trying to study) Sorry for lots of text, I'm simply don't know how to explain my questions shorter :-D I want to configure Kamailio as dispatcher, registrar and NAT traversal in front of FS farm. I've managed to set up Kamailio and Fswitches. Now I need to handle "special cases" with confs, REFER transfers etc Giovanni Maruzzelli once presented solution for this, with following logic: ------------------------------------------------------------------------------------------------------- 1) Kamailio by default distribute calls to various FSs - dispatch or load_balance 2) Each time Kamailio sends a call to a FS, it writes down which destination "number" is going to which FS server and from which UserID 3) if another call comes for the same (or related) destination, or is originated from the same UserID then Kamailio sends the call to that same FS server, bypassing default distribution algorithm ------------------------------------------------------------------------------------------------------- Sounds good and helpful, but I'm stuck :-( *Can someone please share an example or point me how and in what form should I write down call info,and how can I control it (delete on BYE or CANCEL)?* Actually there are 2 questions It seems to me that recordings can be made using HTABLEs but here's a problem: ===================================================================================== ============================================================================================= 1) PROBLEM WITH WRITING TO HTABLE ON ATT TRANSFER After the dispatcher sets $du - I write an htable entry $sht(fsdest=>$fU:$rU) = $du; Existing entries are removed on catching 'BYE' for normal clearing, and with failure_route for all failures. BYE logic is: IN WITHINNDLG route if (has_totag()) { if (loose_route()) { if (is_method("BYE")) { if (sht_match_name("fsdest", "eq", "$fU:$rU")) { $sht(fsdest=>$fU:$rU) = $null; //BYE A->B } else { $sht(fsdest=>$rU:$fU) = $null; //BYE A<-B } } handle_ruri_alias(); route(RELAY); } } Another entry is setting up if blind transfer is made. If INVITE is coming from one of FSs, and have 'Referred-By' field. IN DIALOG route: if (is_present_hf("Referred-By")) { $sht(fsdest=>$fU:$rU) = $si; } For now it's working. Entries are written and deleted properly. *Problem with Attended transfer.* 1) A --> B = htable entry A:B=xxxx 2) A --> C = htable entry A:C=xxxx(checked and set same FS addr because $fU is present (If only it's worked as it should)) 3) Att transfer (Refer $rU B, referred-by - A. Refer-To - C) B --> C = all related entries deleted from table over BYE logic. 4) No entry B --> C (no INVITE was sent, bridged by REFER) So, logic for check active calls in htable is broken now, because we don't have entry B-->C *How can I handle writing to htable in Attended transfer case?* If another Invite will come FROM or TO B or C = there will be no htable entry. I'm not sure this is even a correct way. Surely missing something. ============================================================================================= ============================================================================================= 2) PROBLEM WITH IDENTIFYING TABLE ENTRIES Anyway, the main problem is with identifying those htables to set proper $du. If INVITE is coming TO FSs I need to check if caller ID ($fU) or dest ($rU) is present in htables. Form I need to write to hash must be like $fU:$rU Entry must be unique or it will be: 1) rewrited anytime a new invite is going to the same dest. 2) deleted anytime BYE or failure will come eg: If $sht(fsdest=>$rU) = $dd 1) 1000 --> 3200 = htable entry 3200 = xxxx 2) 1005 --> 3200 = htable entry rewriten to the same 3200 = xxxx When 1000 or 1005 leaving conf, it sends BYE and removes entry. So, next call to 3200 may be sent to the wrong FS. Ok, we have a unique entry ($fU:$rU). Checking for active destination: if (sht_match_name("fsdest", "re", ":$rU")) {} If there's an htable with $rU in key - we got a match. Now we need to assign a value from htable to $du. But, I don't know how to get the name of this entry. There's always different $fU: (or $rU if we check for the same caller ID ($fU)). eg: 1000 --> 3200 = htbale 1000 --> 3200 New call 1005 --> 3200 Check sht_match name ":3200" - got match We need to set: $du = $sht(fsdest=>$fU:$rU) But it will be $sht(fsdest=>1005:3200) and we don't have this entry. We need (fsdest=>1003:3200) But i don't see any way to get needed $fU. *Is there any way to search or identify these tables?* ============================================================================================= ============================================================================================= Can someone help me with this, please? :-) Or maybe there is a better way to do this? *My kamailio.cfg routing block in pastebin, if neededhttps://pastebin.com/1PZ0QSDW <https://pastebin.com/1PZ0QSDW>* Thank you!

Topos does not add record-route on invite
by Angelo Sipper 09 Sep '21

09 Sep '21

Hello, We have the following setup on Kamailio 5.3.7 (x86_64/linux) and I am trying to use topos module on Kamailio2 in order to hide our topology but, mostly to reduce the invite size as most of the times we have fragmentation on invites from Kamailio1 as Kamailio1 it adds 2 record-routes and two via as it handles TLS from one side and UDP on the other side and we have found no wat to avoid all this info even with topos enabled on Kamailio1 there is no change on this. UA (OverTLS) -> Kamailio1 (Over UDP)-> Kamailio2 (Over UDP)-> Provider UA :50.50.50.50:5065 (TLS) Kamailio1: 170.170.170.210:5061 (TLS),170.170.170.210:5060 (UDP) Kamailio2: 170.170.170.170:5060 (UDP) Provider: 200.200.200.193:5060 (UDP) Kamailio1 does not run topos. Kamailio2 does run topos and rr with bellow settings: # ------ topos ------ modparam("topos", "db_url", DBURL) modparam("topos", "mask_callid", 0) modparam("topos", "sanity_checks", 0) modparam("topos", "branch_expire", 130) # 3 Min modparam("topos", "dialog_expire", 10800) # 3 Hours modparam("topos", "clean_interval", 60) modparam("topos", "event_mode", 3) modparam("topos", "contact_host", " sbc181.myserver.com") # ----- rr params ----- # set next param to 1 to add value to ;lr param (helps with some UAs) modparam("rr", "enable_full_lr", 0) modparam("rr", "ignore_sips", 1) # 0 = do not append from tag to the RR, 0 = append from tag to the RR modparam("rr", "append_fromtag", 0) # dual RR 0 = No, 1 = Yes when needed 2 = Always modparam("rr", "enable_double_rr", 0) The problem is that on the invite from Kamailio2 to provider, topos adds only VIA kai new contact. No record route at all. So the provider sends multiple 200 ok SDPs to wrong IPs. If I disable topos module on kamailio2 everything works fine except that we have huge invite as another VIA and another record route is added having now three of each and fragmentation is present. *Invite from Kamailio1 to Kamailio2* ------------------------------------------------- 2021/09/08 21:41:57.698823 170.170.170.210:5060 -> 170.170.170.181:5060 INVITE sip:1234567890@sip.myserver.com:5060 SIP/2.0 Record-Route: <sip:170.170.170.210;r2=on;lr;ftag=1b973153-4034-4480-89d3-c47b411bd81e;vsf=AAAAAFpUAgEBBwEAAXABAG5BR0EAQUBCZXJ2b2ljZS5ldQ--;vst=AAAAAAoMDgsBBQcGAgIAdENbQG4AFxNUXAUaGQYXWAocY2UuZXU-;did=ff2.96a;nat=yes> Record-Route: <sip:170.170.170.210:5061 ;transport=tls;r2=on;lr;ftag=1b973153-4034-4480-89d3-c47b411bd81e;vsf=AAAAAFpUAgEBBwEAAXABAG5BR0EAQUBCZXJ2b2ljZS5ldQ--;vst=AAAAAAoMDgsBBQcGAgIAdENbQG4AFxNUXAUaGQYXWAocY2UuZXU-;did=ff2.96a;nat=yes> Via: SIP/2.0/UDP 170.170.170.210;branch=z9hG4bKd703.e095cdba1da1a4b1599119c9135b7838.0;i=8eb41 Via: SIP/2.0/TLS 50.50.50.50:5065 ;received=50.50.50.50;rport=31090;branch=z9hG4bKPj9196e5f9-977c-4a53-a4c0-c0ab82b095da;alias From: 987654321 <sip: 987654321(a)sip.myserver.com >;tag=1b973153-4034-4480-89d3-c47b411bd81e To: <sip: 1234567890(a)sip.myserver.com> Contact: <sip:customer1@50.50.50.50:5065 ;transport=TLS;alias=50.50.50.50~31090~3> Call-ID: cd64414e-77d5-45b4-a52d-74ec7fb5c7ef CSeq: 15776 INVITE Supported: 100rel, timer, replaces, norefersub Session-Expires: 1800 Min-SE: 90 Max-Forwards: 69 Content-Type: application/sdp Content-Length: 231 P-Asserted-Identity: <sip: 987654321(a)sip.myserver.com> v=0 o=- 391641952 391641952 IN IP4 170.170.170.216 s=Asterisk c=IN IP4 170.170.170.216 t=0 0 m=audio 29478 RTP/AVP 8 0 18 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=sendrecv a=rtcp:29479 a=ptime:20 *Invite from Kamailio2 to Provider* ------------------------------------------------- 2021/09/08 21:41:57.715881 170.170.170.181:5060 -> 200.200.200.193:5060 INVITE sip: 1234567890@sbc181.myserver.com:5060 SIP/2.0 Via: SIP/2.0/UDP 170.170.170.181;branch=z9hG4bKd703.d45db1fd910c43c5e7c4f8711a5fca92.0 From: 987654321 <sip: 987654321(a)sip.myserver.com >;tag=1b973153-4034-4480-89d3-c47b411bd81e To: <sip:1234567890@sip.myserver.com> Call-ID: cd64414e-77d5-45b4-a52d-74ec7fb5c7ef CSeq: 15776 INVITE Supported: 100rel, timer, replaces, norefersub Session-Expires: 1800 Min-SE: 90 Max-Forwards: 68 Content-Type: application/sdp Content-Length: 231 P-Asserted-Identity: <sip: 987654321(a)sip.myserver.com> Contact: <sip:btpsh-c9-613903ef-21d75-1@sbc181.myserver.com> v=0 o=- 391641952 391641952 IN IP4 170.170.170.184 s=Asterisk c=IN IP4 170.170.170.184 t=0 0 m=audio 11450 RTP/AVP 8 0 18 a=rtpmap:8 PCMA/8000 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=sendrecv a=rtcp:11451 a=ptime:20 *Bellow you can see the flow* ---------------------------------------- 170.170.170.210:5060 170.170.170.170:5060 200.200.200.193:5060 qqqqqqqqqqwqqqqqqqqq qqqqqqqqqqwqqqqqqqqq qqqqqqqqqqwqqqqqqqqq 21:41:57.698823 x INVITE (SDP) x x +0.003788 x qqqqqqqqqqqqqqqqqqqqqqqqqq> x x 21:41:57.702611 x 100 trying -- your call is x x +0.013270 x <qqqqqqqqqqqqqqqqqqqqqqqqqq x x 21:41:57.715881 x x INVITE (SDP) x +0.018529 x x qqqqqqqqqqqqqqqqqqqqqqqqqq> x 21:41:57.734410 x x 100 Trying x +0.804083 x x <qqqqqqqqqqqqqqqqqqqqqqqqqq x 21:41:58.538493 x x 183 Session Progress (SDP) x +0.014557 x x <qqqqqqqqqqqqqqqqqqqqqqqqqq x 21:41:58.553050 x 183 Session Progress (SDP) x x +0.483907 x <qqqqqqqqqqqqqqqqqqqqqqqqqq x x 21:41:59.036957 x x 183 Session Progress (SDP) x +0.012009 x x <<<qqqqqqqqqqqqqqqqqqqqqqqq x 21:41:59.048966 x 183 Session Progress (SDP) x x +0.988036 x <<<qqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:00.037002 x x 183 Session Progress (SDP) x +0.010960 x x <<<qqqqqqqqqqqqqqqqqqqqqqqq x 21:42:00.047962 x 183 Session Progress (SDP) x x +1.989085 x <<<qqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:02.037047 x x 183 Session Progress (SDP) x +0.010947 x x <<<qqqqqqqqqqqqqqqqqqqqqqqq x 21:42:02.047994 x 183 Session Progress (SDP) x x +3.989064 x <<<qqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:06.037058 x x 183 Session Progress (SDP) x +0.008860 x x <<<qqqqqqqqqqqqqqqqqqqqqqqq x 21:42:06.045918 x 183 Session Progress (SDP) x x +1.178240 x <<<qqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:07.224158 x CANCEL x x +0.002725 x qqqqqqqqqqqqqqqqqqqqqqqqqq> x x 21:42:07.226883 x x CANCEL x +0.000372 x x qqqqqqqqqqqqqqqqqqqqqqqqqq> x 21:42:07.227255 x 200 canceling x x +0.016902 x <qqqqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:07.244157 x x 200 OK x +0.004590 x x <qqqqqqqqqqqqqqqqqqqqqqqqqq x 21:42:07.248747 x x 487 Request Terminated x +0.003547 x x <qqqqqqqqqqqqqqqqqqqqqqqqqq x 21:42:07.252294 x x ACK x +0.003737 x x qqqqqqqqqqqqqqqqqqqqqqqqqq> x 21:42:07.256031 x 487 Request Terminated x x +0.001161 x <qqqqqqqqqqqqqqqqqqqqqqqqqq x x 21:42:07.257192 x ACK x x x qqqqqqqqqqqqqqqqqqqqqqqqqq> x TCP is out of question from the provider.

manually append_branch to lookup result
by David Villasmil 07 Sep '21

07 Sep '21

Hello guys, I'm trying to dynamically add a branch after doing lookup. The user is found, but in some cases I need to add a branch and do parallel forking. So i'm basically doing: route[LOCATION] { if (!lookup("location")) { .... } if (something) { route(BRANCH_TO_EXTRA); } route(RELAY); } route[BRANCH_TO_EXTRA] { $fs = MY_SOCKET; append_branch("sip:$tU@" + $sel(cfg_get.pstn.gw_ip) + ":" + $sel(cfg_get.pstn.gw_port)); return; } For some reason only the branch appended is being used (I have append_branches=1) Ideas?

via header not removed wit hremove_hf()

during testing I need to remove a Via header This is the code snippet route[REPLACE_VIA] { xlog ("L_INFO", "[REPLACE_VIA] Start of block\n"); xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n"); if(remove_hf("Via")) { xlog ("L_INFO", "[REPLACE_VIA] removed Via\n"); } else { xlog ("L_INFO", "[REPLACE_VIA] did not remove Via\n"); } xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n"); and this is the logs output Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_RURI] Start of block Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] Start of block Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] 1 Via headers Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] removed Via Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_VIA] 1 Via headers From the logs it looks like the remove_hf returns true and we have the header removed, but its still counting the Via header and the Via Header is still present when the INVIE is releyed on Regards, Richard

Manage multiple RTP streams with different TO-tags (forking)
by B. Tietz 07 Sep '21

07 Sep '21

Hello, following situation. I have a Kamailio (5.4) using rtpengine to loadbalance calls. If a call from Alice comes in, Kamailio decides to send the call to Carrier B from Bob. Bobs Phone is ringing and the carrier B send a 183 Session Progress with SDP and To-tag=abcd. The SDP has G722 as codec and port 1234. A few moments later carrier B send a second 183 Session Progress with SDP and TO-tag=fghi. The SDP has G711 as codec and port 5678. This is done, to play some funky music as ringtone -.- If Bob answers the call, carrier B sends a 200 OK WITHOUT SDP and TO-tag=abcd. So this should instruct our Kamailio to switch to the first G722 and port 1234. But sadly, this is just not working as expected. We tried to set the flags media-handover and port-latching for the rtpengine options and additionally set a to-tag when using rtpenging_manage. But this doesn't solve the codec change, so we have only audio when Bob answers the call, but no ringtone-music. If we allow G711 only in the outgoing INVITE to Bob, we have also tha ringtone-muisic, because there is no codec-change. Carrier B tells us, they are using a fork-mechanism. Is there something we can do, to support the codec change in 183? Or enforce carrier B to send SDP in 200 OK? Or anything else? Carrier B can not change anything in the ringtone-music-backend. They are stuck on G711. Thanks!

If web client is busy and mobile client is online and registered, the mobile client rings and the caller hears ringback tone. If web client is busy and mobile client is offline, before the mobile client receives push notification and registers, web client sends 486 busy response and caller hears busy tone. In this last scenario, I want to wait some time for the mobile client to register and ring. I tried to drop 486 response in onreply_route[x], but I found that final responses cannot be dropped in this route. I dropped 486 in reply_route, but I couldn't send an ACK for this transaction. Is there a way to implement this scenario? I would appreciate if you have any suggestions. Thanks, Koray

Add PIDF-LO object to INVITE
by Adarsh Chauhan 31 Aug '21

31 Aug '21

Hi All, I am trying to add PIDF-LO XML to INVITE, however i have had little success so far. My end goal is to create an invite like mentioned in https://docs.microsoft.com/en-us/openspecs/office_protocols/ms-sipre/4010da… I have the following config: request_route{ xlog("L_DBG","REQUEST RECEIVED \n ($mb) \n"); if (is_method("INVITE")) { xinfo("$ua\n"); regex_substring("$ua", "([a-f0-9]{12})",0, 1, "$var(asd)"); if($var(asd)!="") { http_client_query("http://127.0.0.1/location/$var(asd)","$var(result)"); xdbg("$rc ,[$var(result)]\n"); if(!has_body("application/pidf+xml")) { set_body_multipart("$rb", "application/sdp", "delimiter"); msg_apply_changes(); append_body_part($(var(result){s.unquote}), "application/pidf+xml"); msg_apply_changes(); } }else { xerr("NO MAC ADDRESS FOUND\n"); } } route("forward"); } which achieves the following but doesn't have the xml in the correct format.

What does "tls.reload" actually do?
by Sebastian Damm 30 Aug '21

30 Aug '21

Hi, I noticed a strange behavior on some of our proxy servers, all running Kamailio 5.3.8. After running for some time (weeks), our monitoring system sporadically starts reporting errors. The check connects via tls and registers to an Asterisk behind the proxy server. When this happens, the Kamailio log shows the following line: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1409441B:SSL routines:ssl3_read_bytes:tlsv1 alert decrypt error When restarting Kamailio, the problem goes away only to come back after some weeks uptime again. On one host, I tried to find something using kamcmd, and I don't know why but I also issued "tls.reload". And from that point, the monitoring system has not reported the system as faulty anymore. I repeated the same thing on other hosts when the problem occured there, all with the same result. "tls.reload" helps. But from the documentation, I don't know why. Does anybody have an explanation for it? Regards, Sebastian

MS Teams outbound calls. Called number normalization
by Володимир Іванець 25 Aug '21

25 Aug '21

Hello all! I'm testing integration with MS Teams. I treat calls from Teams to the phone system the same way as calls from phones. And would like to ask if someone has already dealt with this. My test account location is set to the United States. When I make a call to "200", an INVITE request from Teams to Kamailio will have "+1200" in the To URI user. I could just strip "+1" but when I make a call to "100", Teams sends "+100". So in this case I need to strip only one character. The problem is that I don't know when I need to remove one or two characters. And it gets more complicated when I change my test account location. For some countries, Teams prepend 3 characters. What do to make sure phone numbers are consistent? I thought this behavior could be disabled in Teams but could not find anything related yet. Thank you! Regards, Volodymyr Ivanets

Race conditions upon quick reinvite
by David VILLAUME 24 Aug '21

24 Aug '21

Hello, We encounter sometimes reinvite from some provider really quickly after 200 OK ACK so sometime there a race conditions where the re-invite exits Kamailio before the ACK leading to some Freeswitch “500 Overlapping Requests”. [cid:image001.png@01D798FA.6F5B9D80] I tried to catch the 500 on failure-route unsuccessfully as transaction is already established. Do you have any idea on how I could deal with this behavour ? Running 5.3.6 with 8 childs modules used :(tm + dialog) No costly action performed on ack that can explain slowliness. Regards, David

Some questions about drouting module
by Андрей Яри н 23 Aug '21

23 Aug '21

Hello! I test module on Centos 7, kamailio version 5.5 and found some strange things: 1) Definition of table dr_gateways at https://kamailio.org/docs/modules/5.5.x/modules/drouting.html#idm98 - in DB there is field 'attrs' and only notice about it is module param 3.8. attrs_avp but it doesnt describe table field. In OpenSIPS docs i found description * attributes (not used by DR engine, but only pushed to script level when routing to this GW) In kamailio this field is deprecated or its only docs misses param? 2) Previous moment was found when i try to resolve: WARNING: drouting [dr_load.c:529]: dr_load_routing_info(): route <1> does not exist "Definition of dr_rules table" says that field has type of integer, but realy in database its varchar and i think its old docs. But i use KEMI question is - how i can tell module that it must be called in KEMI, not in native? 3) Every time when i call 'kamcmd drouting.reload' i get message CRITICAL: <core> [core/mem/q_malloc.c:502]: qm_free(): BUG: bad pointer 0x7f3e4cea04c0 (out of memory block!) called from core: core/utils/tmrec.c: tmrec_free(393) - ignoring I rollback to 5.4 and still get this error. As i understand its old module and its can be internal error - how critical this error can be? 4) Also planned commands like drouting.dump gws|gw_lists|rules? -- С уважением, Ярин Андрей Анатольевич инженер, группы управления телефонией Группа компаний «Интерсвязь» e-mail: yarin-aa(a)intersvyaz.net

Kamailio as basic dispatcher for load balancing
by Philipp Trenz 23 Aug '21

23 Aug '21

Hey there, I’m Philipp, an IT Systems Engineer from Potsdam, Germany and want to deepen my knowledge in SIP communication on scale. Currently, my setup is quite simple: A single stateless Asterisk instance, fully managed via ARI, which registers to multiple VoIP providers, only processes incoming calls to play audio files (no outgoing or conference calls). Now, with growing load on the single Asterisk instance, I would like to have one or two Kamailio instances, which will balance the load of incoming calls to multiple Asterisk instances. On which Asterisk instance they end up is irrelevant for me, as the calls can be processed on every instance. I looked into some Kamailio and Astricon conference speeches and checked out some tutorials. But still I’m not quite sure where to start. So here are some basic questions which would really help me out to get going: As I don’t want to have registrations of all my Asterisk instances at the VoIP providers, I should use the UAC module to let Kamailio do the registering to the VoIP providers and register my Asterisk instances to Kamailio, right? Will Kamailio automatically apply new outbound registrations when added to the database or do I have to trigger that manually? Should I use one or two instances of Kamailio, how hard is it to configure them fail-safe? For writing my first config file, should I start blank or from the standard config, what’s best practice? Thanks in advance, looking forward to your replies! Philipp

How tell if rtp packets are being relayed through rtpengine in kamailio
by Faiz Fazaluddin 23 Aug '21

23 Aug '21

Hi, I want to see if rtp packets are being relayed through kamailio. I am attmepting to connect rtpengine with kamailio, but am not sure if it is working, how can I tell? I have the kamailio server on a different VM than the clients. In wireshark, no rtp packets show on the server VM and rtp packets only seem to be going directly through the client VM. Rtp engine mentions being unable to find hashtables when attempting to implement a delete_node command. Thank you very much for your help, Faiz

Register Forwarding
by Thomas Grande 21 Aug '21

21 Aug '21

Hi there! I bumped into this post to perform forwarding of REGISTER requests and then saving a local cache on 2xx replies from main Registrar: https://lists.kamailio.org/pipermail/sr-users/2020-October/110779.html I think I understand all the steps described, but some features I need are missing: - How to change the Via headers to perform topology hiding? I understand TOPOS and TOPOH do not work on these types of messages. - Change contact header so that registrar responses traverse the Kamailio box. (Use textops I suppose?) - Besides, is this approach still the best in comparison to OpenSIPs mid-registrar module? Thanks in advance, -- *Thomás Alimena Del Grande* Engenharia - Aligera Tel. 51 3500-0121

record_route() from websocket UA to tls UA
by Juha Heinanen 20 Aug '21

20 Aug '21

I noticed that when jsSIP UA that has registered over wss calls another SIP UA that has registered over tls, record_route() adds only one Route URI to outgoing INVITE (example below). This causes BYE to fail. This issue may be caused by the fact that both UAs register over the same Kamailio tls listening socket. Still two Route URIs should be added in the same way as is done when one UA registers over tcp and the other over udp. -- Juha --------------------------------------------------------------------- 09:25:43.639833 wss:87.95.73.155:19458 wss:192.27.134.1:5061 INVITE sip:foo@test.tutpro.com SIP/2.0 Via: SIP/2.0/WSS jovobf9n4svm.invalid;branch=z9hG4bK2639638 Max-Forwards: 69 To: <sip:foo@test.tutpro.com> From: " Test" <sip:test@test.tutpro.com>;tag=f7lpsuo7cb Call-ID: ovhd9fu1fl1a66nec011 CSeq: 1387 INVITE Contact: <sip:test@test.tutpro.com;gr=urn:uuid:e7f92a54-2295-4772-abc8-504be07e94c5> ... 09:25:43.649462 tls:192.27.134.1:5061 tls:87.95.73.155:19461 INVITE sip:foo-0x793ee87a90@10.158.141.103:38378;transport=tls SIP/2.0 Record-Route: <sip:192.27.134.1:5061;transport=ws;sn=ext_tls;lr;n2;dtlsf=avp;pm=0;ice> Via: SIP/2.0/TLS 192.27.134.1:5061;branch=z9hG4bK637c.7e15ef5b84ea054cfc8ea3d4e860521f.0 Via: SIP/2.0/WSS jovobf9n4svm.invalid;rport=19458;received=87.95.73.155;branch=z9hG4bK2639638 Max-Forwards: 68 To: <sip:foo@test.tutpro.com> From: " Test" <sip:test@test.tutpro.com>;tag=f7lpsuo7cb Call-ID: ovhd9fu1fl1a66nec011 CSeq: 1387 INVITE Contact: <sip:test@test.tutpro.com;gr=urn:uuid:e7f92a54-2295-4772-abc8-504be07e94c5>

No docker hub automated builds
by Sergey Safarov 14 Aug '21

14 Aug '21

I found that not more automated builds available on docker hub https://www.docker.com/blog/changes-to-docker-hub-autobuilds/ Looks like we need to make some changes for the alpine docker image. Maybe use github actions for this task? https://docs.docker.com/ci-cd/github-actions/ Sergey

Hi, Couple of week before I have posted feature request - https://github.com/kamailio/kamailio/issues/2807 As suggested, I am trying to figure out how I can achieve it with async or sworker modules. Can someone help me to understand how to use those modules to achieve async connectivity? Regards, Miteshkumar Thakkar

auth challenge freeswitch with Zopier
by Joli Martinez 10 Aug '21

10 Aug '21

Hello, I am using dsiprouter as a public facing server for pass through registrations to a fusion pbx box. This setup works great and has for a long time now. The issue I am having is that we are switching soft phone clients to copier. Zopier uses a push server. When an incoming call comes into the freeswitch server, it fires off an invite to the Zopier registered client. For some reason ONLY in this scenario Kamailio is doing an auth challenge to Freeswitch preventing to call to be sent to the soft phone. How can I stop this from happening? Other soft phones and hard phones work great with inbound calls except for Zopier. thanks,
