Roadmap to the next major release - v5.5.0
by Daniel-Constantin Mierla 16 Jun '21

16 Jun '21

Hello, it is the time to plan a bit the road to the next major release, to be versioned 5.5.0. The 5.4.0 was release by end of July 2020, therefore we are approaching the end of our usual development cycle, also during the last online devel meeting we considered the 2nd part of spring 2021 as a target time frame for 5.5. To narrow it down, I would propose to freeze the development at the end of March 2021, test during April and maybe beginning of May, then release v5.5.0. So far we have a lot of development to existing components, by the freeze date I expect 3-5 new modules to be in the repo as well. If anyone wants a different time line towards 5.5.0, let's discuss and choose the one that suits most of the developers.

Using Kamailio with Asterisk/pjsip outbound_publish - early state is not notified
by Barry Flanagan 15 Jun '21

15 Jun '21

Hi Using Kamailio 5.4 with Asterisk 18 and using the pjsip outbound-publish to allow Kamailio to handle BLF for phones. BLF sort of works, in that when a line is on a call, the BLF reflects that. However the early/ringing state does not generate a NOTIFY to the phone, although Asterisk is sending the Publish and is receiving a 200OK reply from Kamailio. I would presume that since basic BLF is working that this early state PUBLISH should generate a NOTIFY but it doesn't Module params are as follows: # ----- presence params ----- modparam("presence", "db_url", DBURL) modparam("presence", "server_address", "sip:192.168.245.250:5060") modparam("presence", "local_log_level", 3) modparam("presence", "publ_cache", 0) modparam("presence", "timeout_rm_subs", 0) modparam("presence", "sip_uri_match", 1) # ----- presence_xml params ----- modparam("presence_xml", "db_url", DBURL) modparam("presence_xml", "force_active", 1) modparam("presence_dialoginfo", "force_single_dialog", 0) modparam("presence_dialoginfo", "force_dummy_dialog", 1) Any help appreciated! -Barry

Is Kamailio GPL or GPLv2
by Yan Gao 15 Jun '21

15 Jun '21

Hello, I have a question about the license of Kamailio. It is said to be GPL in https://www.kamailio.org/w/: "Kamailio® (successor of former OpenSER and SER) is an Open Source SIP Server released under GPL, able to handle thousands of call setups per second...." But GPLv2 in https://www.kamailio.org/w/info/ : "Kamailio is released under GNU Public License v2 (GPLv2). Beginning with 3.0.0, the application includes parts of code under BSD license that can be used such as individual components." Which one is the correct description? Thanks & Regards, Yan

vsf/vst question
by David Escartín 15 Jun '21

15 Jun '21

Hello all! as we knew vsf/vst were added to the RR header when using uac_replace for From/To headers. BUt we observed that some versions ago (we are using now 5.4) that stop happening with this setup modparam("uac", "restore_mode", "auto") modparam("uac", "restore_dlg", 1) modparam("rr", "enable_full_lr", 0) modparam("rr", "enable_double_rr", 1) modparam("rr", "append_fromtag", 1) and only ftag, did are added as param to RR However we have seen that when using multihomed kamailio instance and doing uac_replace, vsf/vst are included also with ftag and did params. Is that behaviour known or expected? thanks a lot and regards david -- <http://www.sonoc.io/> David Escartín NOC engineer *www.sonoc.io* <http://www.sonoc.io/> [image: LinkedIn] <https://www.linkedin.com/company/sonoc> [image: Twitter] <https://twitter.com/sonoc_> [image: Facebook] <https://www.facebook.com/SONOCio/> This e-mail is for the exclusive use of its recipients and may contain business secrets or other confidential or privileged information.

using path in Subscriber table
by Thành Trần Duy 14 Jun '21

14 Jun '21

Hi all, First of all, I would like to present the system model we are applying: - dSIPRouter : Sip relay for all users connected from the internet (installed with RTPEngine to handle media data). - kamailio 5.3.5: core system, registration server. - Asterisk 17: SBC. Sorry if our model seems a bit backwards but we have so many users (>12k configured users, > 3k concurrent registered users, > 500 concurrent users at cps 10), I don't know of any solution that can work with such a large load. With call outbound (from user to PSTN via SBC), everything is fine. But with internal or inbound calls, it wasn't successful. I showed that: - After dSIPRouter, the register message has Path parameter in SIP Header, - Kamailio store sip:user@domain in column contact at location table. - Using modparam registrar with use_path=1, path_mode=0, path_use_received=1, I stored this parameter in DB. - When calling internal or inbound, for the search destination of a phone, I am using sip_trace() function. But the result is always column contact. - With this uri, kamailio wasn't known and sent the invite to proxy. - Final error message: 404. I need one of these solutions: - get path column when result of sip_trace() like sip:user@domain (with phone in internal network, it like sip:user@ipaddress). - write path value to column contact when the register message has it. - sip_trace can get a path instead of contact if it has. Or you can have other solutions, pls help me. We can talk and test via my Webex PMR. Many thanks, Thanh Duy Tran

Kamailio SBC+ Freeswitch as media server
by John Tuxies 09 Jun '21

09 Jun '21

in a Debian system i am running Kamailio 5.5 installed from repo and with the basic setup i have 2 users 101 & 102 to be able to call each other. So far so good. i added Freeswitch in the same system and tried to follow this guide http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc even though it is old and there are many changes.

Any way to force socket used to reach databases ?
by David VILLAUME 08 Jun '21

08 Jun '21

Hello, I’m trying to initiate a redis connection in ndb_redis for topos_redis on a keepalived slave host, but host tries to use the VIP instead of the second socket I defined. Is there a way to influence the ‘database source socket’ so the server can connect with a secondary address even if it does not own the keepalived VIP (tried mhomed options without improvment) ? Regards, David

Questions on http_async_query() in event_route[xhttp:request] and async best practices for Kamailio
by James Aylett 04 Jun '21

04 Jun '21

Hi, I am using Kamailio v5.2 as a WebRTC proxy for SIP clients, as part of my setup I call a REST API before calling ws_handle_handshake() in event_route[xhttp:request] using http_client_query() to authenticate and retrieve some user details (routing etc) for the user connected via WebSockets. This worked fine until increased load on the system meant API responses were slow, this caused a knock-on effect to existing connected users. Specifically, we saw mass WebSocket disconnects for existing connected users - believed to be due to using too aggressive proxy timeout settings on our reverse proxy in front of Kamailio. My understanding is that event_route[xhttp:request] uses the shared SIP TCP worker threads, so potentially could slow API requests over the network block all the handlers? Could this potentially impact the keepalive processes used by the WebSocket module to check existing WebSocket connections? We were using ping keepalives, again with pretty aggressive timers... To resolve this issue, I am looking at whether I can call API requests asynchronously so that TCP workers are not blocked, my first thought was to use http_async_query() in event_route[xhttp:request] and call ws_handle_handshake() in the HTTP_REPLY route when the API call had completed, but I get "ERROR: websocket [ws_handshake.c:143]: ws_handle_handshake(): retrieving connection". I presume then this approach is a deadend, looking at newer kamailio versions 5.5, there doesn't seem to be any way to do this, correct? Instead of using http_async_query() in event_route[xhttp:request], I presume I could set a short timeout in http_client_query(), but my concern is new WebSocket connections could still impact and block existing ones in this case... My other thought was to move my API call out from the event_route[xhttp:request] into my route handler for REGISTER requests, thinking I could offload new register requests to async workers and move the API call there so as to not block existing connections. Does this seem like a reasonable approach to the problem? Given my current script does not use any async workers, how would one go about optimising the number of plain SIP TCP workers to async workers, are there any guides for this? In general, for any potentially blocking "APIs" or calls over the network, is it best practice to offload them into async workers. For example, we run RTPEngine on separate hosts to Kamailio so should I be wrapping rtpengine_offer/answer calls into async workers in case of a slow network? Apologies for the long text, but I would really appreciate any help to understand these problems. Thank you

handle_ruri_alias() and multiple aliases
by Denys Pozniak 02 Jun '21

02 Jun '21

Hello! I need help understanding how the *handle_ruri_alias()* function works. *Call-flow:* Upstream operator -> Kamailio Proxy -> Edpoint. The upstream operator in the initial SIP INVITE in the Contact field sends us an alias parameter, in turn, our Kamailio Proxy adds its own too. The Contact after the Proxy looks something like this: *Contact: <sip:10.0.0.115:5060;alias=10.0.0.115~5060~1;alias=3.3.3.3~5060~1>* When the Endpoint sends us a SIP BYE, then the *handle_ruri_alias()* absorbs not the last alias, but the first one, and this leads to the incorrect formation of a $du. The RURI after the Proxy looks something like this: *Request-Line: BYE sip:10.0.0.115:5060;alias=3.3.3.3~5060~1 SIP/2.0* The first thing that comes to mind is a modification of the original Contact field with storing it's within a dialogue ... Is it possible to elegantly solve this problem? -- BR, Denys Pozniak

kamailio 5.4.5 crash after dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg
by Trevor Hemsley 02 Jun '21

02 Jun '21

Hi We've seen a few occurrences of this crash since we implemented kamailio 5.4.5 for our inbound call traffic. Preceding the crash we always get a message in the logs about "dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg" and whenever we see that message, we get the crash. Jun 1 10:12:14 thissystem /usr/sbin/kamailio[20001]: CRITICAL: {2 1 INVITE 6787142-3831531134-1330894187(a)some.telco.domain} dialog [dlg_hash.c:1182]: next_state_dlg(): bogus event 2 in state 5 for dlg 0x7fae153d3cf0 [3973:6059] with clid '82608924-3831089984-1833452161(a)some.telco.domain' and tags '3831089984-684203260' '' The crash happens on line 879 of https://github.com/kamailio/kamailio/blob/master/src/modules/dialog/dlg_db_… SET_STR_VALUE(values+7, cell->bind_addr[DLG_CALLER_LEG]->sock_str); Looking at gdb, I see that cell->bind_addr[DLG_CALLER_LEG] == 0 so trying to use it results in the segfault. I have thought about patching that to check for bind_addr being set and bypassing that line if not but I do not think it's the right fix though it probably would avoid the current crash (and do odd things later instead!). I did check that everything else in that function that uses DLG_CALLER_LEG is set correctly and it appears that it is - or at least if not correctly then they are at least set! The "bogus event 2 in state 5" message is coming out from line 1143 in src/modules/ims_dialog/dlg_hash.c case DLG_EVENT_RPL1xx: switch (dlg->state) { case DLG_STATE_UNCONFIRMED: case DLG_STATE_EARLY: dlg->state = DLG_STATE_EARLY; break; default: log_next_state_dlg(event, dlg); } break; (I didn't really understand why it would set dlg->state = DLG_STATE_EARLY if it's already DLG_STATE_EARLY but...) I have a couple of core dumps of this from the last day or two - usually seems to crash at least once a week on our pair of kamailio inbound servers. If there's any more info I can provide to help fix this properly rather than my proposed bodge then feel free to ask.

UAC module register originating from private interface on server
by Jonathan Hunter 02 Jun '21

02 Jun '21

Hi, I am working with the UAC module and trying to register with providers, and can see that kamailio keeps sending the REGISTER from the private IP address socket on the server (eth0). Is it possible to set the default socket or send socket for the REGISTER message that gets sent out via kamailio? I am running version 4.4.7. I notice SIP OPTIONS are being sent out from the public IP address (eth1) on the server (as I have set socket in dispatcher) and was hoping for same behaviour with uac module. Please can anyone advise? Many thanks Jon Sent from Mail<https://go.microsoft.com/fwlink/?LinkId=550986> for Windows 10

Possible memory leak?
by George Diamantopoulos 02 Jun '21

02 Jun '21

Hello all, I've been experiencing memory exhaustion (all 8GiB of it) on hosts running kamailio for quite some time now while on the 5.4.x train. I can't really say about previous versions, because the setup was quite different back when I was using those. After about 2 days of operation, RAM is exhausted and kamailio is killed by the kernel OOM which frees up memory again. Restarting kamailio via systemd will also free up most memory. I can't seem to find what is using it up, so I'm guessing there might be a memory leak, but I'm not 100% sure so I thought I'd ask the list for opinions. I'm including the output of kamcmd pkg and shm stats and kamctl stats here. My take on those is that there's nothing to show where all this RAM is going. Kamailio version is 5.4.5+bpo10 on debian buster and is started with '-P /run/kamailio/kamailio.pid -f /etc/kamailio/kamailio.cfg -m 2048 -M 16' (51 processes total).

IMS IPSec does use UDP socket?
by H Yavari 01 Jun '21

01 Jun '21

Hi to all, I am interested in the implementation of IPsec module. When I run Kamailio, it is creating processes based on the below formulate: UDP children * IPSEC_MAX_CONN * interfaces (v4 and v6) + (TCP+UD) processes for each interface. For example: children = 16tcp_children=16 IPSEC_MAX_CONN = 25and two interface : IPv6 and V4 Kamailio process count = (16 * 25 * 2 ) + 16 + 16 = 832 But why IPsec module is listening to UDP not TCP? this is an internal connection? Thank you. Regards,Hossein

SDP body, add maxptime attribut
by Victor Velo 01 Jun '21

01 Jun '21

Hello, I would like to add the maxptime attribut to the sdp body. How and where should I do insertion? This kamailio is also using RTPEngine, so is it better to do the insertion using RTPEngine? And the source of the SDP is actually FreeSwitch :), maybe there to tweak? Of course, I don't know either way of doing it so please advise. Thanks, Victor

Good afternoon All, Im hoping for some advise or direction with the below. We are running a Kamailio SBC used for high call volumes and recently decided to upgrade the Database servers as the existing servers were struggling. Both the old and new databases are using MariaDB(version details all below), the problem we face is that since migrating to the new database there appears to a limitation to the amount of DB connections that can be processed or accepted. The SBC functions normally until the CPS starts to exceed around 100cps at which point the SBC stops responding to invites(in bursts which resembles flood prevention). We have checked both the Kamailio logs and the MySQL logs on the DB, both log files have no indication of errors that would cause the problem experienced(the logs attached are seen when the SBC is cut back to use the old DB, not sure they are related to the fault), the connections/processes in mysql do not drastically increase or get stuck either. The fault points to a db connection limit of some kind but all users have no limitations set. If anyone has experienced a similar problem or has any advise it would be greatly appreciated. Some info on the Kamialio and DB versions New DB root@voice-jhb-db01:~# mysql --version mysql Ver 15.1 Distrib 10.3.27-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2 Old DB [root@isadb01 ~]# mysql --version mysql Ver 15.1 Distrib 10.0.36-MariaDB, for Linux (x86_64) using readline 5.1 Kamailio SBC [root@sbc01 ~]# kamailio -v version: kamailio 5.1.4 (x86_64/linux) Kind regards, Stephen Voice Engineer Tel: 2404 Fax: 3468 Email:

Architecture - your opinion is welcome and your experience too
by Daian Conrad 28 May '21

28 May '21

Hi all, I am studying and improving my understanding of how kamailio works, I have used asterisk for a few years(and starting learning freeswitch too), and I use an application to manage extensions, trunks and other media services. I'm building a new scenario where kamailio is facing the internet and the asterisk(s) are internally on private networks, would like the opinion of you who are more experienced with more complex environments than me. I cannot change the application that uses asterisk for now, due to the effort to develop event monitoring, cdr and other features that I use today. I imagined and working on making kamailio functional by saving the registration of extensions with location on DB, and with the UAC module making the registration of extensions on asterisk(s), replacing the registration address with the address of kamailio, its functional at this point, but data replication with extensions turns things some hard to mantain manually. I think about using the DNS domain for each asterisk and make this forwarded, each asterisk response for a fqdn and its extensions, like ( pbx1.example.com is forwarded to asterisk1, pbx2.example.com to asterisk2) and so on. Read about the dispatcher, rr, htable,carrierroute module to identify the domain and forward based on that , none made me sure to be chosen for the role, however, everyone has the resources to do it. I am very wrong to follow this path, which option in your opinion is "less" painful for a beginner apprentice like me? I think about simple proxy based on domain requests(all messages and dialogs) to asterisk where is responsible for the domain(realm) but, loss the ability to use great security features of kamailio, is what I understand now with the knowledge I have. Sorry and forgive my english, i'm not very good at writing. -- ================ **Daian Conrad** E-mail: daian.conrad(a)gmail.com OpenS Team (DaCoD) Linux user: #248912

No Audio For Outbound Calls
by Kashish Raheja 28 May '21

28 May '21

Hi All, I have set up Kamailio in the following manner: Kamailio (Physical Server: Register to Telecom Operator Carrier SIP trunk) ---> Asterisk Server (on Cloud having public IP) I am successfully able to route the call to Asterisk server on Cloud when I make a call to the number provided by the carrier and there is audio also on both sides. However, when I am making an outbound call from Asterisk server to the number through Kamailio, there is no audio when I pick up the call. I have tried to capture the traces but not able to understand the exact problem here. Note: I am running the RTP proxy on Kamailio server. Any help on why this might be happening? Thanks. Regards Kashish +919413745250

Hello, I have question regarding of call forking on kamailio. Maybe somebody can help me. For example I have table like +--------------+---------------+--------------+---------------+--------------+ | First number | Second number | Third number | Fourth number | Fifth number | +--------------+---------------+--------------+---------------+--------------+ | A number | B number | C number | --- | --- | +--------------+---------------+--------------+---------------+--------------+ Table 1: Extra_numbers or separated by comma +--------------------+-----------------------------+ | First_number | Additional_numbers | +--------------------+-----------------------------+ | Primary number | 2nd,3rd number | +--------------+-----------------------------------+ Table 2: Extra_numbers +--------------------+---------------------------------+ | First_number | Additional_numbers | +--------------------+---------------------------------+ | Primary number | 2nd number,3rd number,4 number | +--------------------+---------------------------------+ Table 3: Extra_numbers If kamailio get the call (INVITE) to some number/extension (for example, "1st number"), then in routing I request (select `Additional_numbers` from `Extra_numbers` where First_number='1 number';) from the mysql database and there I check, if "Additional_numbers" exists in the database. Then I add "Additional_numbers" to the routing, and generate INVITE to "Additional_numbers" and 1 number. (always) set r-uri ($ru) to first destination (2 number) set r-uri ($ru) to second destination (3 number) set r-uri ($ru) to Third destination (1 number) set r-uri ($ru) to n destination How could this be done?

Body formats for filter_body()
by Duarte Rocha 27 May '21

27 May '21

Hello all, A couple years ago the function filter_body() from textops would only work with "application/sdp" if the string on the body was "Content-Type: application/sdp\r\n". It would fail if there wasn't a space after ":" and it would fail if there was present "\r\n\r\n" instead of "\r\n". Is this the actual behaviour of the function or has it been changed to also identify SDP in the formats mentioned above? Best Regards,

26 May '21

Hi, I'm using Kamailio version 5.3.7 with DISPATCHER module and I would like to integrate my kamailio with a kamailio_exporter for monitoring using Prometheus server. Is it possible to collect data such as the number of total calls (inbound, outbound) and plot time-graphs using those stats? If so, what modules/functions would I need apart from the Dispatcher module to be able to have efficient results? Any degree of help will be appreciated. *Hisham Jan* *VoIP Engineer* *0322-6398775*

Kamailio 5.3.8 and RTPengine 9.4.1.1+0~mr9.4.1.1
by Mihai Cezar 23 May '21

23 May '21

Hi All, I've been using Kamailio as a proxy for asterisk (with public ips), everything was fine until i've changed the setup to private ips for asterisk. What I did so far: - Kamailio and rtpengine are on a box with 1 public IP. - Asterisk containers on private ips each asterisk has 2 trunks ( 1trunk voip provider 1trunk the Proxy). What works: - Proxy registrations and sip signaling works. What it does not work: - On the asterisk I got only on rtp connexion, my guess is that has something to do with the SDP, asterisk put the private ip in the SDP header. RTPengine is configured using this guide https://github.com/sipwise/rtpengine Can you have a look at the kamailio config, i think i am missing something or do something wrong. Thank you! command to start was: rtpengine --table=42 --listen-ng=127.0.0.1:2223 --interface=public/110.20.20.1 --tos=184 --pidfile=/run/rtpengine.pid --no-fallback and the Kamailio cfg is this: #!KAMAILIO #!define FLT_ACC 1 #!define FLT_ACCMISSED 2 #!define FLT_ACCFAILED 3 #!define FLT_FS 10 #!define FLT_NATS 5 #!define FLB_NATB 6 #!define FLB_NATSIPPING 7 #!define WITH_DEBUG #!define WITH_NAT ## This is the main configuration file for our proxy! ####### Global Parameters ######### #!ifdef WITH_DEBUG debug=4 memdbg=5 memlog=5 log_stderror=yes disable_core_dump=no sip_warning=yes #!else debug=-0 log_stderror=no sip_warning=no disable_core_dump=yes #!endif log_facility=LOG_LOCAL0 fork=yes children=8 auto_aliases=no port=5060 disable_tcp=yes server_id = 1 server_signature=yes server_header="Server: proxy" dns_try_ipv6=no dns_try_naptr=no dns_retr_time=1 dns_retr_no=1 rev_dns=no ####### Modules Section ######## #loadmodule "db_mysql.so" loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "registrar.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "acc.so" loadmodule "dispatcher.so" loadmodule "path.so" loadmodule "nathelper.so" loadmodule "rtpengine.so" ####### Modules Settings # ----------------- setting module-specific parameters --------------- modparam("xlog", "buf_size", 4096) modparam("xlog", "prefix", "xlog: ") modparam("xlog", "log_facility", "LOG_DAEMON") modparam("xlog", "log_colors", "L_ERR=cr") modparam("xlog", "log_colors", "L_ERR=cr;L_WARN=px") # ----- jsonrpcs params ----- modparam("jsonrpcs", "pretty_format", 1) # ----- tm params ----- modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) # ----- rr params ----- modparam("rr", "enable_full_lr", 1) modparam("rr", "append_fromtag", 0) #!ifdef WITH_NAT modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@proxy") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("rtpengine", "rtpengine_sock", "udp:127.0.0.1:2223") modparam("rtpengine", "rtpengine_retr", 2) modparam("rtpengine", "hash_table_size", 256) modparam("rtpengine", "hash_table_tout", 600) #!endif # ----- registrar params ----- modparam("registrar", "method_filtering", 1) modparam("registrar", "append_branches", 0) modparam("registrar", "max_expires", 3600) modparam("registrar", "gruu_enabled", 1) # ----- acc params ----- modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 0) modparam("acc", "detect_direction", 0) modparam("acc", "log_flag", FLT_ACC) modparam("acc", "log_missed_flag", FLT_ACCMISSED) modparam("acc", "log_extra", "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd;src_ip=$si") modparam("acc", "failed_transaction_flag", FLT_ACCFAILED) # ----- dispatcher params ----- modparam("dispatcher", "list_file", "/etc/kamailio/plugins/dispatcher.list") modparam("dispatcher", "xavp_dst", "_dsdst_") modparam("dispatcher", "xavp_ctx", "_dsctx_") modparam("dispatcher", "ds_ping_from", "sip:ping@proxy") modparam("dispatcher", "ds_probing_mode", 1) modparam("path", "use_received", 1) ####### Routing Logic ########### # main request routing logic request_route { # per request initial checks route(REQINIT);

Can Kamailio help with this?
by Antony Stone 22 May '21

22 May '21

Hi. I've been aware of Kamailio, and on this list, for several years, but so far I have not implemented Kamailio for any purpose. I wonder if it could be a suitable tool for the following scenario. I currently use Asterisk to register as a client, with username and password, to other SIP PBXs in order to receive calls. As far as the other PBX is concerned, Asterisk looks like a SIP telephone on a particular extension. However, Asterisk's SIP client capabilities are limited to handling phone calls only, and it specifically cannot receive presence information about the state of other extensions from the remote PBX. So, could Kamailio be used in the path between Asterisk and the remote PBX so that the registration on the PBX comes from Kamailio (with any incoming calls being passed to Asterisk), but with Kamailio also receiving presence information from the remote PBX and making this available to some script or application (which I would expect to have to write)? The main point is that I don't want to have two things registering to the remote PBX, one for calls and one for presence, so I'm looking for a way to register with something which understands presence, and can also pass calls on to Asterisk. Can anyone suggest whether Kamailio could do this, and if so, point me at some resources to help me get started; or alternatively suggest ideas on some other tool which might be more appropriate than Kamailio? Thanks for any ideas, Antony. -- Schrödinger's rule of data integrity: the condition of any backup is unknown until a restore is attempted. Please reply to the list; please *don't* CC me.

Video transcode for doorbell
by Luke Kenny 21 May '21

21 May '21

I have a SIP video doorbell device that is only capable of sending H264 and MJPEG video. The site is using 3CX and its associated mobile app, which only supports VP8 and VP9. Without properly reading the documentation, I went ahead and set up kamailio and rtpengine to sit in between the doorbell and 3CX. I has assumed rtpengine was capable of transcoding video as well as audio, however upon proper inspection it appears that isn't the case. Is there a kamailio module that is capable of video transcoding, even if it isn't real time, or at a reduced framerate? As the application is a doorbell, it doesn't need to be perfect. Many thanks, Luke Kenny

Eternal config - Kamailio and rtpengine
by Mihai Cezar 20 May '21

20 May '21

Hi! I use lxc containers with asterisk wich their are connecting to kamailio, so far so good they work when i put the containers with public ips, but when i switched to private ip I have one-way audio. I tried to with rtpengine but no luck: rtpengine --table=42 --listen-ng=127.0.0.1:2223 --interface=56.12.19.100 --tos=184 --pidfile=/run/rtpengine.pid --no-fallback --log-level=7 --log-facility=local3 the setup looks like this: VM-KAMAILIO-(public ip 56.12.19.100 with static routes for the private IP) --> LxC(n) (with private class 192.168.0.n) The problem i think is when LxC asterisk is sending back the 200 OK from Invite it puts his private ip in the sdp filed: v=0 o=- 2171376102 3 IN IP4 192.168.0.2 s=Asterisk c=IN IP4 192.168.0.2 t=0 0 m=audio 11336 RTP/AVP 8 101 a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=ptime:20 a=maxptime:150 a=sendrecv i've loaded the modules, but after this i am stuck.... loadmodule "nathelper.so" loadmodule "rtpengine.so" modparam("nathelper", "received_avp", "$avp(RECEIVED)") modparam("nathelper", "nortpproxy_str", "a=sdpmangled:yes\r\n") modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) modparam("nathelper", "sipping_bflag", FLB_NATSIPPING) modparam("nathelper", "sipping_from", "sip:pinger@proxy") # params needed for NAT traversal in other modules modparam("nathelper|registrar", "received_avp", "$avp(RECEIVED)") modparam("usrloc", "nat_bflag", FLB_NATB) modparam("rtpengine", "rtpengine_sock", "udp:localhost:2223") modparam("rtpengine", "rtpengine_retr", 2) modparam("rtpengine", "hash_table_size", 256) modparam("rtpengine", "hash_table_tout", 600)

Permissions sometimes does not find group
by Romain Untereiner 19 May '21

19 May '21

Hello all, I am having some trouble with Permissions module of Kamailio, regarding the allow_source_address_group() function. In 99.9% of the cases the IP of our partner is allowed as expected, but randomly it can fail (returning -1 for the same IP address that was allowed for many other calls in the meantime). I can’t understand why it fails and why only « sometimes » - I confirm this append on the same Kamailio box, with same IP and Port of the partner. In my custom logs: « X.X.X.X:YYYY is allowed through group Z » —> as expected and sometimes (like 1% of the cases): « X.X.X.X:YYYY is not allowed - allow_source_address_group returned -1» It is maybe to note that in the address table, this range is defined as /24 and not /32. Until now it never happened on /32 defined address but I don’t know if it can be correlated. Would someone have a clue on this? Versions: - kamailio 5.5.0 (x86_64/linux) d4c1a1 - debian 9 stretch - postgresql 11.7 Many thanks! Romain Untereiner Co founder at Cantoo www.cantoo.co

Kamailio as Load Balancer
by Melek Oktay 19 May '21

19 May '21

Hi, I have been investigating distributing incoming/outgoing SIP traffic to behind Kamailio SIP servers in order to scale and other advantages too!. SRV type distribution is not a good option, it is already tested. So, I am trying to deploy Kamailio as a *LoadBalancer* in Tier1 , so it distributes traffic backbone Kamilio servers in Tier 2. There is a good presentation as follows, actually I want to implement it. https://www.kamailio.org/events/2013-KamailioWorld/23-Daniel-Constantin.Mie… However, I could not find sample configurations and sample study ! Would you show me sample configurations that Kamailio uses as a Load Balancer if you have it. Current Kamailio responsibilities in my system are: 1. Registar Server 2. Presence Server 3. Sip proxy server 4. WebSocket Maybe it will be very good to separate *Registar *Server & *Presence *Server, but could not find sample configurations too. Best Regards Melek P.S. If we could collect such configurations, I would share them for community on Github.

Hello, I am new to kamailio. And I Am following the work of Franz Edler. I would like to test it in a local environment without internet connection on ubuntu. What I don't understand is, to download the packages I necessarily need the internet. Do I have to use two network interfaces for the same virtual machine in order to access the internet and make the DNS configuration locally with the second interface?

Hunting Kamailio.cfg for Voice termination System
by Edo 16 May '21

16 May '21

Hi, I am looking to get a complete kamailio.cfg file that I can use to set up a voice termination system. This system will only connect with peers making multiple simultaneous calls, registering strictly via ip, accounting calls to sql db, capable of multiple rate tables for the different peers, call control, CDR tool and billing capable and call routing to multiple media servers. I am willing to try to build this myself but at this time I do not even understand why I need to use "record_route" or "t_precheck_trans" -- :)). I am a lover of information and cannot find a simple enough text to help in my kamailio journey -- unlike asterisk. If you are interested please respond to me directly at edo.ekunwe(a)gmail.com and I am willing to pay for this information or guidance(if you have the patience and time to mentor me). Thanks -- ----- Nogie Ekunwe

loose_route() and FQDN
by Igor Olhovskiy 14 May '21

14 May '21

Hello, I saw there are some topics on this already and carefully walked through all of them, but can't solve following issue. For a reason I do need that in Record-Route header sent to endpoint would present FQDN. If it matters, it's UDP/WSS conversion done on Kamailio. So, scheme is quite simple Enpoint A ->UDP-> Kamailio ->WSS-> Endpoint B (NAT) Main issue here, that if in Record-Route headers it's FQDN, but not IP addresses, on a new transactions with a dialog (ACK on 200, PRACK, BYE), Kamailio*loose_route()* function resolves address of destination not current dialog, but actual R-URI (or itself, if R-URI is something from WebRTC world) that is not correct due to NAT. If in RR headers IP addresses are present - all is working as expected. As an example (RR with FQDN) B answers 200 SIP/2.0 200 OK Record-Route: <sip:KAMAILIO_FQDN:8089;transport=ws;r2=on;lr=on;ftag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d;nat=wss> Record-Route: <sip:KAMAILIO_FQDN;r2=on;lr=on;ftag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d;nat=wss> Via: SIP/2.0/UDP <A_IP_ADDRESS>:5060;received=A IP ADDRESS;rport=5060;branch=z9hG4bKPj67fb6d86-97d7-4231-995b-e54b0f62881e To: <sip:88290@<KAMAILIO_FQDN>>;tag=hvra7mj3q0 From: <sip:+XXXX7688881@<KAMAILIO_FQDN>>;tag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d Call-ID: 46f44741-d155-4dd5-8fd8-78e540fc1acb CSeq: 18326 INVITE Contact: <sip:88290@toleivu2gdbh.invalid;transport=wss> Allow: ACK,CANCEL,INVITE,MESSAGE,BYE,OPTIONS,INFO,NOTIFY,REFER Supported: outbound Content-Type: application/sdp Content-Length: 817 ACK looks like ACK sip:88290@toleivu2gdbh.invalid;transport=wss SIP/2.0 Via: SIP/2.0/UDP A_IP_ADDRESS:5060;rport;branch=z9hG4bKPj8d05548a-91ef-4332-8617-32f8eeebf8f2 From: <sip:88881@A_IP_ADDRESS>;tag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d To: <sip:88290@KAMAILIO_FQDN>;tag=hvra7mj3q0 Call-ID: 46f44741-d155-4dd5-8fd8-78e540fc1acb CSeq: 18326 ACK Route: <sip:FQDN;lr;r2=on;ftag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d;nat=wss> Route: <sip:FQDN:8089;transport=ws;lr;r2=on;ftag=0a3e31a6-96ad-42d0-9310-81b35cedbd3d;nat=wss> Max-Forwards: 70 User-Agent: Asterisk PBX 13.33.0 Content-Length: 0 And Kamailio on *loose_route()* loops ACK to itself. (with result of function == 1) In a case if in Record-Route/Route headers just IP address of Kamailio present, all works as expected, but it's not really behavior I want to achieve. I've tried to play with *record_route_preset("...")* specifying only WSS part (as suggested in https://skalatan.de/de/blog/kamailio-sbc-teams) with FQDN, but no luck. Also wanted to try approach using record_route_preset() function in branch route, but it was working only with first branch, not affecting others (but I assume having different RR headers across branches is not a good idea) -- Regards, Igor

Setting $conid per branch
by Marrold 14 May '21

14 May '21

Hi all, I'm currently adding a feature to our Kamailio configuration to fork calls based on user agent. To do so I'm getting the registered endpoints with reg_fetch_contacts() iterating through and matching on them, then using seturi() / append_branch() and setting the dst-uri and flags as required. However, calls are intermittently going to the wrong TCP connection, despite the logs showing the correct destination IP and port in the ONSEND route. Looking in the location table I can see each registration has a connection_id, and the debug log indicates it's finding the connection by ID: DEBUG: <core> [core/tcp_main.c:1651]: _tcpconn_find(): found connection by id: 3 Is there a way to set the conid per branch? Is it necessary? We're using kamailio 5.3.3 on Debian 10. Thanks Matthew

Possible to get the value of $DLG_lifetime before the BYE hits loose_route()
by ryan embgrets 13 May '21

13 May '21

Greetings, I would like to know if it is possible to get the value of $DLG_lifetime before the BYE hits loose_route(). opensips provides a similar function which lets you get dialog life. https://opensips.org/html/docs/modules/3.1.x/dialog.html#func_load_dialog_c… But i could not get the same from kamailio or maybe kamailio has a better way for this? Thanks for any pointer. Ryan

Bad config - you can not call 'handle_publish' function (db_url not set)
by Marrold 13 May '21

13 May '21

Hi, We're trying to upgrade from 5.3.X to 5.4.5 however kamailio will not start and produces the following error, despite the db_url being set in the config and printed in the logs: Bad config - you can not call 'handle_publish' function (db_url not set) Looking at the code this error only seems plausible if the *pres_library_mode* is set to 1 here <https://github.com/kamailio/kamailio/blob/cc2a9518207e36b7b18aef5c8714f0c21…> but we don't see the corresponding "switch to library mode" message in the debug logs which leaves me a bit stuck - I've included the grepped logs at the bottom of the message. Does anyone have any ideas what is causing this issue? I've seen a previous issue relating to interactions between presence and presence_xml which we're also using, but it looks like this was fixed in an older version.

bogus event with terminated dialogs with late 200ok responses
by David Escartín 12 May '21

12 May '21

Hello all using kamailio version 5.4.4, we are seeing some errors like CRITICAL: dialog [dlg_hash.c:1205]: next_state_dlg(): bogus event 3 in state 5 (with BYE) for dlg 0x7f6ca2304b48 [15135:39671] with clid '00463385_20210512_002_HPRA_1.1.4.40.sp3_7532_0_54533900281' and tags 'Out-55089-0000000CB27947F9' '170cB11c48vmj' which seem to be generated when we receive a BYE from the remote UA but we were expecting an ACK also, For example INVITE ----------> <---------------183 <---------------200 BYE -------------> (no ACK) <--------------200 <--------------200 .... so the b2bua (freeswitch) keeps retransmitting the 200ok, and on each 200ok retransmission we are getting this type of message. These seem to be like race conditions since 200/BYE flow almost at the same time, and as I understand, the UA should send the ACK. But my doubt is if these errors can be harmful for the kamailio or they can be ignored and address the issue to the remote UA on each case thanks a lot and regards david -- <http://www.sonoc.io/> David Escartín NOC engineer *www.sonoc.io* <http://www.sonoc.io/> [image: LinkedIn] <https://www.linkedin.com/company/sonoc> [image: Twitter] <https://twitter.com/sonoc_> [image: Facebook] <https://www.facebook.com/SONOCio/> This e-mail is for the exclusive use of its recipients and may contain business secrets or other confidential or privileged information.

Kamailio as front proxy for multiple sip servers
by Eliphas Levy Theodoro 10 May '21

10 May '21

Hello! I am trying to config one kamailio as reverse proxy for a bunch of internal (no internet address) separate asterisk sip instances (per domain). The kamailio server would be the only with the valid IP address, so would use rtpengine to force to be in the media path. Like this scenario: https://opensips.org/pipermail/users/2020-August/043610.html I have used as starting point this very basic config: https://blog.voipxswitch.com/2015/03/27/kamailio-basic-sip-proxy-all-reques… Basically just added rtpproxy support, and voilà, inter-SIP is working, media always passing into the proxy. The problem: I would have WebRTC phones connecting too. I tried setting WSS up in kamailio, and asterisk (pjsip) wouldn't know how to send the message to the proxy: on register it has trasnport=wss in the contact: header, looks like it is confusing the asterisk. So, I resort for the wisdom of the list :) What would be the good-best-path to take here, hack the header, or put the webphones registering directly on the asterisks (with a nginx reverse proxy maybe)? Someone must have already made a blog with such setup, but I could not google-unearth it at least until now. Regards, -- Eliphas

start_recording and stop_recording inside event_route[xhttp:request]
by Володимир Іванець 05 May '21

05 May '21

Hello! I'm testing call recording with Rtpengine. It works fine when the "record-call=on" flag is added to the *rtpengine_offer* or *start_recording* is used in the *request_route*. But I was wondering if the call recording can be managed by a separate application. So I add the following lines to the *event_route[xhttp:request]* and triggered it with an HTTP request after the call was established. The call-id value was taken from the Rtpengine log and sent with the request. * if ($hu =~ "^/CALL_RECORD_START/") {* * $var(call_id) = *"call-id=" + *$(hu{s.select,2,/});* xlog("L_DBG", "$var(call_id)"); * start_recording($var(call_id));* exit; * }* In this case, Kamailio will log errors and will not send the Rtpengine command to start call recording. *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <script>: call-id=3de74068278ede4417086eb82bdf5a06@127.0.0.1:5080.0* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: DEBUG: <core> [core/parser/msg_parser.c:89]: get_hdr_field(): found end of header* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine_funcs.c:294]: get_callid(): call-id not found* *Apr 27 18:25:00 test /usr/sbin/kamailio[5347]: ERROR: rtpengine [rtpengine.c:2383]: rtpp_function_call(): can't get Call-Id field* Have anyone tried to call functions *start_recording* and *stop_recording* inside *event_route[xhttp:request]*?

dialog OPTIONS
by David Villasmil 05 May '21

05 May '21

Hello guys, I'm using the dialog module, params are: # ----- dialog params ----- modparam("dialog", "db_mode", 0) modparam("dialog", "dlg_flag", 20) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) modparam("dialog", "ka_failed_limit", 2) modparam("dialog", "send_bye", 1) modparam("dialog", "timer_procs", 1) When receiving an INVITE, i'm doing dlg_set_property("ka-src"); dlg_set_property("ka-dst"); dlg_set_property("timeout-noreset"); I have a couple questions: The flow is the following: clientA>-\ kamailio<->freeswitch clientB<-/ Kamailio receives an INVITE from ClientA, which I forward to freeswitch, which in turn forwards it back to Kamailio. In reality I would like to monitor only the client legs, but I'm having problems, so I'm enabling OPTIONS on all legs. On the ClientA legs, I see OPTIONS going from kamailio to both freeswitch and the client. But on the ClientB legs i don't see any OPTIONS at all. Can someone point me in the right direction to enable it on all legs? Something else i'm seeing is even though i set "ka_failed_limit" to 2, kamailio is sending several OPTIONS before sending BYEs to both legs (clientA, since there are no OPTIONS on clientB) Thanks all, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

by Daniel-Constantin Mierla 05 May '21

05 May '21

Hello, after almost 4 weeks since development was frozen, it is time to plan releasing the next major stable version, respectively 5.5.0, therefore I propose to do it on Wednesday, May 5, 2021. The branch 5.5 was already created about one week ago, several doc resources were published (core/variables/transformations/rpcs/stats cookbooks, alphabetic indexes, ...). If anyone is testing an upgrade from branch 5.4 to 5.5 and encounters changes that should be done in Kamailio config, add notes about at: * https://www.kamailio.org/wiki/install/upgrade/5.4.x-to-5.5.0 Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - Online May 17-20, 2021 (Europe Timezone) - June 7-10, 2021 (America Timezone) * https://www.asipto.com/sw/kamailio-advanced-training-online/

Can't make tcp_conid_alive work with $var
by David Villasmil 03 May '21

03 May '21

Hello guys, I'm trying to do the following: On INVITE, i add a param to RR "wsconnid" which is the connection id of the WS socket. Afterwards, i get an OPTIONS including said param. Next I want to retrieve the param and check if the connection is alive. NOTE: using simply "$(hdr(Route){param.value,wsconnid})" returns an extra ">" from the end of the string, and i haven't been able to remove that any other way but with "striptail", it works fine. *** $var(conid) = $(hdr(Route){param.value,wsconnid}); $var(conid) = $(var(conid){s.striptail,1}); xlog("L_ERR", "Connection ID parameter: [$var(conid)]"); if (tcp_conid_alive("$var(conid)")) { xlog("L_ERR", "WS Connection ID $var(conid) is alive"); } else { xlog("L_ERR", "WS Connection ID $var(conid) is NOT alive"); } *** With that, "$var(conid)" contains the connection id properly: *** ERROR: <script>: Connection ID parameter: [2] *** but tcp_conid_alive complaints: *** ERROR: <core> [core/sr_module.c:1638]: get_int_fparam(): Could not convert PV to int ERROR: tcpops [tcpops_mod.c:374]: w_tcp_conid_state(): invalid parameter 'conid' (must be a number) *** Using a hardcoded number such as "1" generates no complaints. Kamailio version: version: kamailio 5.3.7 (x86_64/linux) Not sure what's going on here, any ideas? Regards, David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

named account with multiple numbers
by beer Ll 03 May '21

03 May '21

Hi I have a configuration with sip accounts which authenticate with the real name of the customers ex: customer1(a)sip.myvoip.dev customer2(a)sip.myvoip.dev ... INBOUND call of multiple numbers are connected with alias_db to the accounts ex: +331234567890 | sip.myvoip.dev | customer1 | sip.myvoip.dev | +331234567891 | sip.myvoip.dev | customer1 | sip.myvoip.dev | +341234567893 | sip.myvoip.dev | customer2 | sip.myvoip.dev | +341234567894 | sip.myvoip.dev | customer2 | sip.myvoip.dev | ... and all works perfectly. OUTBOUND call after authentication with the username kamailio change the caller id and the ip of my ISP-SIP-TRUNK to relay the call with the correct CID for the ISP using the variable $fn (display name in the From header) [SIP-GW-ISP] { #out with ISP route(CID); $ru = "sip:" + $rU + "@" + "IP_ADDRESS_MY-ISP"; route(RELAY); exit; } ROUTE[CID] { $var(caller) = $(fn{re.subst,/"//g}); uac_replace_from("$var(caller)","sip:$var(caller)@$fd"); } Is possible do it with a different approach for example using Remote-Party-ID , PPI P-Preferred-Identity ? Is possible to check if the customer uses the correct outbound number present in the alias_db table ? ex for customer1 only +331234567890 or +331234567891 numbers many thanks Luca

Hello, the "new in Kamailio 5.5.x" document has been updated. Again, a really impressive set of changes that lead to this release: Over 1350 commits have been done in the last development period from over 70 individual contributors. You find the document at the usual place in our wiki: https://www.kamailio.org/wiki/features/new-in-5.5.x Many thanks to everybody who contributed to Kamailio. Help in updating the documentation (e.g. core cookbook, pseudo-variable and transformation section) in the wiki is really welcome, as some content is probably still missing there.

Dialog server behind proxy and ka_timer/ka_interval
by David Villasmil 30 Apr '21

30 Apr '21

Hello guys, So i have a setup where client | V (WS) [proxy (no dialog tracking)] | V [dialog server] | V [proxy (no dialog tracking)] (WS) | V client I'd like to know when any of the clients are not available (i.e.: crashed, shutdown unexpectedly. etc), so i enabled on the dialog server ka_timer/ka_interval. I see the OPTIONS going to the proxy when the call starts, and the proxy replying with 200 OK. If i shutdown the client, i see the OPTIONS still going, but the proxy is still responding. I assume the Proxy (kamailio) is simply responding to an OPTIONS message and not actually trying to resend it to the client. Is there anyway of doing this or something better to accomplish the same thing? Thanks! David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

Development for v5.5.x is frozen
by Daniel-Constantin Mierla 30 Apr '21

30 Apr '21

Hello, the formal notification that the development for the next major version 5.5.0 is now frozen. The focus has to be on testing the master branch. Also, the master branch should not get commits with new features till the branch 5.5 is created, expected to happen in 2-4 weeks, a matter of how testing goes on. Meanwhile, the commits with new features in the C code can be pushed to personal branches, new pull requests can still be done, but they will be merged after branching 5.5. Can still be done commits with documentation improvements, enhancements to related tools (e.g., kamctl, kamcmd), merging exiting pull requests at this moment, exporting missing KEMI functions and completing the functionality of the new modules added in 5.5. Once the branch 5.5 is created, new features can be pushed again to master branch as usual. From that moment, the v5.5.0 should be out very soon, time used for further testing but also preparing the release of packages. If someone is not sure if a commit brings a new feature, just make a pull request and it can be discussed there on github portal or via sr-dev mailing list. A summary of what is new in upcoming 5.5 is going to be built at: * https://www.kamailio.org/wiki/features/new-in-5.5.x Upgrade guidelines will be collected at: * https://www.kamailio.org/wiki/install/upgrade/5.4.x-to-5.5.0 Everyone is more than welcome to contribute to the above wiki pages, especially to the upgrade guidelines, to help everyone else during the migration process from v5.4.x to 5.4.x.

To-Tag on Register Refresh method
by Duarte Rocha 28 Apr '21

28 Apr '21

Hello all, I'm using Kamailio as a registrar and i have an endpoint that sometimes sends a REGISTER method with a To-Tag when refreshing its regist. My code on this proxy shares many similarities with the default kamailio.cfg configuration file. On that occasion Kamailio answers with a 404 - Not Here since it treats it as a in-dialog request which fails the loose_route check. Why would a CPE send a REGISTER with a To-Tag? Why is a REGISTER with a To-Tag rejected by Kamailio when it could otherwise be a successful REGISTER? Is this behaviour noncompliant with the SIP protocol? I thought about making an exception in the code and having this register following the same path as a register without to-tag, but i don't know if that is unsafe and/or noncompliant with the protocol. Best Regards,

In case of topology: A - P1 - P2 - P1 - B is the idea to use in P1 context "in" when initial request comes to P1 from A or B and context "out" when initial request comes to P1 from P2? Does context need to be set in replies too? If so, is reply context the same as the corresponding request context? And finally, does context need to be set for in-dialog requests/replies the same way as for initial requests? -- Juha

In config file I have: debug=2 mem_summary=0 Still I get 3400+ memory related syslog message when Kamailio terminates due to sqlops not been able to connect to mysql server. According to core cookbook, memdbg and memlog should not be active when their values are greater than debug value (they default to 3) and mem_summary=0 should disable printing of memory debugging info. What is it that I'm still missing? -- Juha

[ANNOUNCE]: sipnagios, a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc)
by Giovanni Maruzzelli 23 Apr '21

23 Apr '21

Hello fellow VoIPers and RTCers, on GitHub there is an early release of sipnagios, opensource. check it out: https://github.com/gmaruzz/sipnagios sipnagios is a Nagios Plugin to check Call Quality in SIP VoIP (compatible with checkmk, etc) sipnagios implements the Nagios plugin API for monitoring and performance data.sipnagios.c is a modification of the original siprtp.c sample in pjproject distribution. Supposedly, it works on Linux, Windows, and anywhere you can compile pjproject on.It makes a call, checks all the various resulting values (mos, rtt, pdd, tta, jitter, packet loss, bytes and packets transferred, and so on). It verifies these values are included into acceptable, warning, or critical ranges.If the call has gone well, sipnagios print performance data for Nagios graphs, and returns 0.If the call fails, or if its measured values are not inside acceptable ranges, it exits with Nagios conventional WARNING or CRITICAL values. mos calculation is scraped from Julien Chavanton work (VoIP Patrol, on GitHub too) I can't even understand :) (merci Julien!)

Development is open for future release of v5.6.x series
by Daniel-Constantin Mierla 22 Apr '21

22 Apr '21

Hello, the branch 5.5 was created, therefore the master branch is open for adding new features, to be part of future release series v5.6.x (or whatever version is decided for next series). Any bug fix committed to master that applies to 5.5.x or older stable branches should be backported as usual with "git cherry-pick -x ..." to appropriate branches like 5.5 or 5.4. Expect that v5.5.0 will be released in a few weeks from now. Based on the workflow used during the past years, the next future release v5.6.0 should be out after another 6-10 months of development, plus 1-2 months of testing, so sometime by end of 2021 or in the first part of 2022.

Reminding again about private/direct emails from mailing lists discussions
by Daniel-Constantin Mierla 22 Apr '21

22 Apr '21

A lot of emails are still sent directly to me after a discussion started on public mailing lists (subject with mailing lists prefix, but the sender header is not the mailing list daemon), I would like to remind that, at least in my case, writing emails directly without cc-ing the mailing list is highly not recommended and there is practically 0 chance to get an answer from myself. The rule is also suggested in the mailing lists presentation page: - https://www.kamailio.org/w/mailing-lists/ Unless I asked explicitly for a private email with some specific details, the message will not be noticed in decent time and therefore not replied. I use this email address for many public mailing lists and it is intended only for that usage, I am reacting based on the filters I created, unmatched messages getting the lowest priority. Therefore if you wrote me and expect a response, re-send the message to the appropriate public mailing list. Checking and answering the messages on Kamailio mailing lists are among the top of priorities on my daily activity, so it is high chance you get the response faster when you write there. Note that you can always mask sensitive data (e.g., replace passwords, IP addresses) before sending logs or config file. There are several common sense as well as technical reasons for keeping the discussion on public mailing lists. Here are some along with other suggestions to improve the likeliness of getting an answer: - we are not answering questions on mailing lists to help only one person, but also other people that may have similar issues in the future -- they can find the answers in the archive with a search engine. Also, other people subscribed to the list can learn from conversation or contribute to the discussion, resulting in better outcome - the amount of unexpected messages is very high -- it is practically a zero chance to get to the folder with messages that didn't match any filter (thus your message is not going to be replied) - whenever I find time, the first emails I answer are those coming on mailing lists. There might be many unanswered as well, people are travelling or having other personal or business projects, so sometime is good to send a reminder if a question does not get an answer - starting with negative approach or no technical content, like you are going to use something else if you don't get a reply instantly, or this application not good or is missing what so ever tutorial giving exactly the solution you need, or simply asking for full config of complex requirements, is not helping at all, but actually making people to ignore your messages. Start with what you tried and where you got stuck. Everything you get is for free, have appropriate expectation and behavior.

Branching 5.5 on git repo for 5.5.x releases
by Daniel-Constantin Mierla 21 Apr '21

21 Apr '21

Hello, since freezing the development for 5.5 series, I did quite a lot of code analyzing with a bunch of tools as well as run various tests, no major issue being in my list at this moment, therefore I think we can plan branching 5.5 on git repo in the near future. If there is no other suggestion or argument against it, I propose to create the branch 5.5 on Thursday next week (April 22, 2021). After that, master branch will be open for new features (to become part of 5.6 or what ever version will be decided to be next), testing will continue for branch 5.5 for another 1-2 weeks, then we will release 5.5.0 as first stable version in the 5.5.x series.

Dialog - Profile cleanup before event_route[dialog:end]

Hello guys !!! i'm a beginner in kamailio technology and i want to use kamailio http_client module to get data from API, but i got : Access error : Unauthorized Access Denied Wrong Password My user IDs are correct. API's encryption is MD5 (digest Auth ). So i use: modparam("http_client", "authmethod", 2) ... modparam("http_client", "cipher_suites", "ecdhe_ecdsa_aes_128_gcm_sha_256, rsa_aes_128_gcm_sha_256") then modparam("http_client", "cipher_suites", "rc4-md5") Can someone help me please ?

Kamailio 5.4.4 and Siptrace
by pwerspire 20 Apr '21

20 Apr '21

Hi list, I have the following configuration for siptrace: #################### modparam("siptrace", "duplicate_uri", "{{ homer_uri }}") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_flag", 22) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", 2070) ####################### But we saw that local replies from Kamailio in some cases would not appear. For example, Invite is sent to Kamailio and Kamailio replies with a Forbidden, in homer only the Invite and the ACK would appear. So any scenario that the Invite has the final answer locally on Kamailio would not appear the reply in Homer. I tried to use the following modified config: #################### modparam("siptrace", "duplicate_uri", "{{ homer_uri }}") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "trace_mode", 0) modparam("siptrace", "hep_version", 3) modparam("siptrace", "hep_capture_id", 2070) and in the Request Route: request_route { sip_trace_mode("t"); .... } ####################### With this last configuration, I can see now all the messages (for example the forbidden appears) but we found out a problem with this configuration. In a normal scenario if we have some mapping for example from 487 to 480 in the onreply_route { .... change_reply_status(480,"Temporary unavailable"); ..... } in homer it will appear that Kamailio received the 480 instead of the 487, so basically siptrace is reporting the message after being change instead of the original message received. Any ideas what I need to change on the siptrace to have this correctly working? Thanks for the help, Regards, Tiago

Create accounta with multiple DIDs
by John Tuxies 19 Apr '21

19 Apr '21

I am novice in the area and i have a Kamailio basic setup where i create users and each user can call each other. No connection to an ITSP. i am trying to simulate things and need to send multiple numbers to each user. For example i have users 1000-1003. I need each user to have a range of 100 numbers (fake since it ia not connected anywhere) and routed to all the other users as well. The idea is to connect Asterisk servers and each one have a registered account 1000-1003. Then each Asterisk's extension have a particular DID and call another Asterisk server to a different DID. Off course this will go through Kamailio. Now i call from one Asterisk to the other by using the 1000-1003 and it works. But i need the DID routing

Info: regression for AVP with integer ID on v5.4.5
by Daniel-Constantin Mierla 16 Apr '21

16 Apr '21

Hello, a notification to inform about a regression to the AVPs with the integer IDs that was introduced in the v5.4.5 release when trying to fix an issue reported from a static code analyzer/fuzzer. The workaround is to use string names for AVPs, so if you have AVPs like $avp(i:123), they can be changed to $avp(s:123) in the kamailio.cfg (ie., replace i: with s: ). Regression is already fixed in the git branch 5.4, so if you install it from there, all should be ok. For Debian packages, you can wait till tomorrow and use the nightly builds of 5.4.x series from the repos listed at: * http://deb.kamailio.org/#dev54 Cheers, Daniel -- Daniel-Constantin Mierla -- www.asipto.com www.twitter.com/miconda -- www.linkedin.com/in/miconda Kamailio Advanced Training - Online May 17-20, 2021 (Europe Timezone) - June 7-10, 2021 (America Timezone) * https://www.asipto.com/sw/kamailio-advanced-training-online/

15 Apr '21

Hello, Kamailio SIP Server v5.4.5 stable release is out. This is a maintenance release of the latest stable branch, 5.4, that includes fixes since the release of v5.4.4.

Hello, I am considering to release Kamailio v5.4.5 sometime next week, likely on Thursday, April 15, 2020. This is the usual heads up notification to see if anyone is aware of issues not yet reported to bug tracker and if yes, do it as soon as possible to give them a chance to be fixed.

potential PRACK related topos bug
by Juha Heinanen 14 Apr '21

14 Apr '21

Test topology using K 5.4 where topos module is loaded in Proxy1: A - Proxy1 - Proxy2 - Proxy1 - B A sends INVITE, B responds with 183 Session Progress, and A sends PRACK. The result is that PRACK starts to loop in second Proxy1 instance instead of being forwarded to B. If topos module is not loaded in Proxy1, it forwards PRACK to B as it should. Also, if Proxy1 loads topos module, but A does not send PRACK, other in-dialog requests (e.g. BYE) work fine. -- Juha

Using kamailio-python with python 3.7
by Aaron Lucia 13 Apr '21

13 Apr '21

Hello, We have been using the kamailio-python plugin with kamailio, running on CentOS 7. The RPM for the kamailio-python plugin has a requirement on the python36 package. I'm curious if it's possible to run kamailio with the kamailio-python plugin with python 3.7 or if python 3.6 is required. If it is possible to use the kamailio-python plugin with python 3.7, would we need to create our own RPM with a requirement on python37 or is there another way we could set it up? Thank you very much for your feedback, Aaron Aaron Lucia | Software Engineer 100 High Street, 7th Floor, Boston, MA 02110 USA www.cogitocorp.com | Cogito on LinkedIn <https://www.linkedin.com/company/cogito-corp-/> | Office: 617.580.3101 Confidentiality Notice : This email is the property of Cogito Corporation.

KEMI - Set message body to Bytes / Prevent parsing PV?
by Nick 13 Apr '21

13 Apr '21

Hi all, I'm trying in KEMI & Python to set a Pseudo Variable to the value of another PV (simple enough) but the value of the PV is not a string or an integer, For example the SMSops <https://github.com/kamailio/kamailio/tree/master/src/modules/smsops> module has a PV called $smsbody which I need to set the message body to equal in UAC, but I'm not able to load it to set it as the message body, In my Python file I have: smsbody = KSR.pv.get("$smsbody") Which leads to: kamailio[226069]: UnicodeDecodeError: 'utf-8' codec can't decode byte 0x91 in position 7: invalid start byte kamailio[226069]: 2(226069) DEBUG: app_python3 [apy_kemi.c:112]: sr_kemi_config_engine_python(): execution of route type 1 with no name returned -1 *Is there a way to set a PV in Kemi without actually interpreting it?* *Is there a way to run an arbitrary line of native Kamailio config from Kemi like KSR.x.modf? * In reality all I need to do is: $uac_req(body) = $smsbody; Would work fine in the native config, but the equivalent in Kemi tries to parse the contents and fails, so can't set the body.

Dispatcher and SUBSCRIBE issue
by Barry Flanagan 08 Apr '21

08 Apr '21

Hi I am using the dispatcher module with Kamailio as a front-end Registrar/LB in front of a cluster of Asterisk boxes. I have come across an issue with SUBSCRIBE messages not getting routed to the correct server in the event that the phone endpoint's dispatch set is changed. It will still go to the old server until such time as the phone is rebooted. The reason this is happening is because the 200 OK in the response from the Asterisk server has Contact set to its own IP:port and subsequent in-dialog reSUBSCRIBE are sent with the original Asterisk ip:port in the RURI. When Kamailio receives these reSUBSCRIBE it does not change the RURI even though ds_select_dst is being called in the [WITHIN_DIALOG] route. My feeling is I have two choices - either alter the Contact in the reply from Asterisk, or, change the RURI manually on receipt of an in-dialog SUBSCRIBE. Has anyone else come across this, or have advice on the best way to handle this? Thanks -- -Barry

I am not familiar with the IMS extensions, if nobody else comes with other suggestions, I recommend to set debug=3 in your kamailio configuration file and then look at the syslog, there should be a lot of DEBUG messages that may give more hints about what happens. Also, when sending Kamailio logs, do not make screen shots, just copy and paste them, it is easier to read as well as search in the source code for them by copy&paste.

How to handle SIP-I(ISUP) with Kamailio
by Waseem Zaidi 06 Apr '21

06 Apr '21

Hi All: I am new to the list, I am struggling to find out Kamailio's capabilities with SIP-I/ISUP. I see that there is SIP-T module in kamailio and ss7ops module, but I need to get a hold on how to start. I would appreciate if someone could guide me. previously, I tried to use OpenSIPS SIP-I to extract ISUP from incoming calls, i was able to extract ISUP parameters in SDP body as xlog("Called Number: $isup_param_str(Called Party Number|Address signal)\r\n"); xlog("Calling Number: $isup_param_str(Calling Party Number|Address signal)\r\n"); xlog("Location is: $isup_param_str(Location Number)\r\n"); Location parameter is appearing as 0x04971400330268 which is wrongly interpreted. its proper interpretation should appear as 4100332086. I also tried below: xlog("Location is: $isup_param_str(Location Number|Address signal)\r\n"); but this subfield is not present. The transformation didn't make any difference: xlog("Location NUM: $(var(isup_body){isup.param, Location Number} Help pleeez ?

Phase III clinical trials of Kamailio DMQ
by Alex Balashov 01 Apr '21

01 Apr '21

For immediate release: GAINESVILLE, Florida (1 April 2021)--Evariste Systems, in partnership with Posner | Palner Pharmaceuticals, are pleased to announce the eagerly anticipated start of Phase III clinical trials of Kamailio DMQ module replication. In this stage of the investigation of the promising replication scheme, which was developed in record time, DMQ will be tested in a rigourous, double-blind, controlled CI/CD process for large-scale efficacy and continually monitored for safety in shorter and longer terms. The now-concluded second phase established basic safety and Phase 2b entailed a dose-finding study for the optimal number of batched `dmq_usrloc` contacts per kilogram of cloud computing resource. The main cohort of the main sequence of the Phase III trial will enroll 380 randomly selected, statistically representative Floridian SIP registrars and 5700 SIP dialogs, also in the state of Florida. When asked about the disparity in the number of registrars versus dialogs, Alex Balashov of Evariste said, "It is reflective of the small number of SIP registrars in Florida; not to be indelicate, but consider the median age of the population." As previously remarked upon in proceedings of the World SIP Organisation (WSO), the choice of Florida as a venue attracted some questions. We asked Fred Posner of Posner | Palner about the clinical background informing this choice of replication study cohort: "Florida is a good place to find eventual consistency failures; the open climate and reluctance to accept traditional data integrity science would have sealed the deal, but when people started to drink bleach here, I saw an opportunity." Evariste and Posner | Palner are aiming for a US Food & Drug Administration EUA (Emergency Use Authorisation) for DMQ replication as a prophylactic data redundancy and failover measure to ward off the development of moderate to severe viral Sonus Haemorrhagic Fever symptoms. Phase II studies have painted a promising a picture of the DMQ architecture's ability to reduce moderate to severe symptoms and associated 28-day mortality by more than 90%, albeit over a small sample size and in enterprise patients with known pre-existing comorbidities such as Session Border Controller and BroadSoft Multi-System Inflammatory Syndrome. Phase III trials seek to bolster quantums of broader efficacy, including efficacy for localised outbreaks of small to medium business softswitch. Of the control group, Balashov said, "They will receive a standard pipe-to-/dev/null placebo protocol, but with identical '200 OK' confirmation messages. We proudly developed this approach in early 2020 in consultation with the highest levels of the Trump presidential administration; it is called TENP, or 'The Emperor's New Potion.' It is a successor to that administration's previous approved placebo protocol, SHTI - Small Hands, Tremendous Initiatives." Despite speculative autism and packet fragmentation claims by Florida Governor Ron DeSantis, Balashov was quick to provide reassurance about side effects from DMQ in the Phase III trial. "The incidence of severe allergies to plain-text UDP was within standard deviation over the mean for all insecure replication, and there's support for other transports on the way. Anyway, we have a robust adverse effects reporting system in our issue tracker and solid surveillance. Don't let partisan politics dissuade you from allowing request lines with the KDMQ method." Other industry sources have reported that DMQ is not the only replication investigation undertaken by Evariste and Posner | Palner, although it is the only prophylactic suitable for the early infection development and inflammatory phases of a broad class of SBC-complex syndromes typically afflicting service providers. A recent IETF preprint by the same authors has shown high-quality preliminary data suggesting statistically significant improvement in morbidity outcomes from Perimeta and Nokia via a later-stage therapeutic intervention with a monoclonal, monorepo Github cocktail administered intravenously. -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Kamailio + Websocket issues
by Vinicius Kwiecien Ruoso 01 Apr '21

01 Apr '21

Hi! I'm using Kamaio in front of multiple Asterisk instances. At this moment it works as a SIP over Websocket proxy, with rtpengine, for browser clients to connect to Asterisk using WebRTC. I do not use the registration module of Kamailio, as each backend Asterisk is independent and handles its own registrations. Everything works great when making calls from the browser, and the routing is correctly executed by Kamailio based on the request SIP domain. We have an internal routing API that it calls to discover which backend Asterisk to route the calls. The issue I have is when a call initiates from that backend Asterisk, trying to reach a contact that is connected in Kamailio via the websocket. The Asterisk sends the message to the proxy, and Kamailio must route it to the corresponding websocket. I've tried a few approaches: - using add_contact_alias + handle_ruri_alias: I have the alias with alias=<ip>~<port>~ws in the contact registration, but for some reason handle_ruri_alias cannot use it - using the Path module on Asterisk, so when registering, the path is recorded and sent back from Asterisk, Kamailio is also not respecting that - Using contact_param_encode and contact_param_encode and contact_param_decode_ruri, but the encoded sip address is always the invalid websocket, like sip:58c0ktrg@5hp0nn5hqqv9.invalid;transport=ws None with success. Any hints on that can be wrong? I can share more detailed information. Greetings, Vinicius

tcp timeout in kamailio
by Alexander Kudrevatykh 01 Apr '21

01 Apr '21

Hi. Is there an option for tcp timeout in kamailio? In my setup we have tcp peers and kamailio pings them every 5 seconds, but when tcp session stucks kamailio not close this session for 15 minutes. I tried many tcp options kamailio supports, but any of them helps. I think kamailio can use TCP_USER_TIMEOUT on linux to detect such tcp sessions and reestablish failed connections?

dispatcher algorithm 11, no more than 25 hosts in group for proper distribution
by Ivan Matvieiev 31 Mar '21

31 Mar '21

Hello Community, There is a module dispatcher and sharing algorithm 11 that features the ability to redistribute load when the host is enabled or disabled that is quite valuable for me. In the test lab I faced unexpected behavior: - when I add to group <=25 hosts algorithm behaves as per description. - when a group includes 26 or more hosts, and 100 calls are done for instance, then about 25 go to the first host and 75 are distributed among the rest of hosts. Expected behavior: all hosts of the group having the same rweight value must receive the same amount of calls no mater what number of hosts is in the group. Could you please to help to figure out what is wrong and why when the dispatcher group consists of 26+ hosts dispatching algorithm 11 behaves differently than when group consists of 25 or less of hosts? Some configuration notes: # module configs modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list") modparam("dispatcher", "flags", 2) modparam("dispatcher", "ds_ping_method", "OPTIONS") modparam("dispatcher", "ds_probing_threshold", 3) modparam("dispatcher", "ds_inactive_threshold", 10) modparam("dispatcher", "ds_probing_mode", 3) modparam("dispatcher", "ds_ping_interval", 10) modparam("dispatcher", "ds_ping_reply_codes", "501,403,404,400,200") modparam("dispatcher", "ds_ping_from",DS_PING_FROM_PARAM) modparam("dispatcher", "use_default", 0) # dispatching algorithm call if ( ds_is_from_list("101")) { sl_send_reply("100","My calls"); ds_select_dst("100", "11"); return; } # dispatcher list group config 100 sip:10.60.27.123:7000 0 10 rweight=50 100 sip:10.60.27.123:7001 0 10 rweight=50 100 sip:10.60.27.123:7002 0 10 rweight=50 100 sip:10.60.27.123:7003 0 10 rweight=50 100 sip:10.60.27.123:7004 0 10 rweight=50 100 sip:10.60.27.123:7005 0 10 rweight=50 100 sip:10.60.27.123:7006 0 10 rweight=50 100 sip:10.60.27.123:7007 0 10 rweight=50 100 sip:10.60.27.123:7008 0 10 rweight=50 100 sip:10.60.27.123:7009 0 10 rweight=50 100 sip:10.60.27.123:7010 0 10 rweight=50 100 sip:10.60.27.123:7011 0 10 rweight=50 100 sip:10.60.27.123:7012 0 10 rweight=50 100 sip:10.60.27.123:7013 0 10 rweight=50 100 sip:10.60.27.123:7014 0 10 rweight=50 100 sip:10.60.27.123:7015 0 10 rweight=50 100 sip:10.60.27.123:7016 0 10 rweight=50 100 sip:10.60.27.123:7017 0 10 rweight=50 100 sip:10.60.27.123:7018 0 10 rweight=50 100 sip:10.60.27.123:7019 0 10 rweight=50 100 sip:10.60.27.123:7020 0 10 rweight=50 100 sip:10.60.27.123:7021 0 10 rweight=50 100 sip:10.60.27.123:7022 0 10 rweight=50 100 sip:10.60.27.123:7023 0 10 rweight=50 100 sip:10.60.27.123:7024 0 10 rweight=50 Kamailio version: kamailio -v version: kamailio 5.4.4 (x86_64/linux) e16352 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_BLACKLIST, HAVE_RESOLV_RES 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: e16352 compiled on 15:56:46 Feb 15 2021 with gcc 4.8.5 System info CentOS Linux release 7.7.1908 (Core) Linux test-carrier-1.loc 3.10.0-1062.4.1.el7.x86_64 #1 SMP Fri Oct 18 17:15:30 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

Strange behavior with $T_branch_idx in failure_route
by Victor Litvinov 25 Mar '21

25 Mar '21

Hello. We faced an issue that $T_branch_idx called from failure_route returned a strange result. Few words about our setup. We use branch indexes like key in avp when we store via-branch value for rtpengine. route[RTPMANAGE] ... if ( is_request() and is_method("INVITE") and !has_totag() and t_is_branch_route() ) { $avp(viabranch$T_branch_idx) = $branch_str; } $avp(extra_branch_id) = $avp(viabranch$T_branch_idx); $var(rtpkey) = $var(rtpkey) + " via-branch=extra"; ...... rtpengine_manage($var(rtpkey)); Call this route in branch_route and in failure_route. In branch_route T_branch_idx is 0, in failure_route is 1. In documentation: the index (starting with 1 for the first branch) of the branch for which is executed the branch_route[]. If used outside of branch_route[] block, the value is '0'. But in source code behavior is different. (modules/tmx/t_var.c:480): for BRANCH_FAILURE_ROUTE and BRANCH_ROUTE it is idx = tcx->branch_index, but for FAILURE_ROUTE it is idx = t->nr_of_outgoings + nr_branches; Can you describe why for failure_route it is different and what we can do in our case? And can you update documentation for this variable if it is wrong?

SDPOPs questions
by Gerry | Rigatta 23 Mar '21

23 Mar '21

Hi, The behaviour of the sdpops module is not fully clear to me. Lets say in the INVITE contains in the m= line the payloads 0 99 but has no a= line for codec 0 / PCMU, Would the sdp_keep_codecs_by_name(“PCMU”) keep PCMU ? What about the case that the INVITE contains in the m=line only the payload 99 but shows an additional a=line for codec 0 / PCMU. Would the sdp_keep_codecs_by_name(“PCMU”) keep PCMU ? If yes, would the extra mtype parameter prevent that? e.g. sdp_keep_codecs_by_name(“PCMU”, mtype) What happens when several m= lines are present? Does sdp_keep_codecs_by_name consider all m=lines ? Are the treated separately? What happens to payloads which are not in the hard-coded list in sdpops_data.c ? Can they be used with the sdpops functions? Thanks for your hints. Best Gerry codecsmap_t sdpops_codecsmap_table[] = { { {"PCMU", 4}, {"0", 1} }, { {"GSM", 3}, {"3", 1} }, { {"G723", 4}, {"4", 1} }, { {"DVI4", 4}, {"5,6,16,17", 9} }, { {"LPC", 3}, {"7", 1} }, { {"PCMA", 4}, {"8", 1} }, { {"G722", 4}, {"9", 1} }, { {"L16", 3}, {"10,11", 5} }, { {"QCELP", 5}, {"12", 2} }, { {"CN", 2}, {"13", 5} }, { {"MPA", 3}, {"14", 2} }, { {"G728", 4}, {"15", 2} }, { {"G729", 4}, {"18", 2} }, { {0, 0}, {0, 0} } };

Dynamic CSEQ Updates
by Tyler Moore 23 Mar '21

23 Mar '21

Hey kamailio team, When are the callbacks in the dialog module for updating $dlg_var(cseq_diff) called? I am trying to dynamically enable / disable cseq updates (some specific carriers need it and some don't) by setting $dlg_var(cseq_diff)=$null prior to sending the request but it seems like the callback happens after relaying. For example I tried various locations: - prior to t_relay() - in onreply_route[] - in failure_route[] - in event_route[tm:local-request] - in event_route[tm:local-response] I also tried setting modparam("dialog", "initial_cbs_inscript", 1) and calling dlg_manage() prior to routing and those didn't seem to be the right callbacks either. Either the callback that updates $dlg_var(cseq_diff) occurs after t_relay() / forward() is called or setting $dlg_var(cseq_diff)=$null has no effect. Is dynamically turning CSEQ updates on / off possible by overwriting $dlg_var(cseq_diff)? Or would this require new logic in the dialog module to be supported?

Kamailio + rtpengine + Freeswitch on public/private network
by Eric Ravelo 20 Mar '21

20 Mar '21

Dear Kamailians, I have Kamailio+rtpengine as a dispatcher in front of FreeSWITCH. Kamailio and FreeSWITCH are on the same private network (in an AWS VPC). Kamailio receives calls on the Public Internet IP address and port, and dispatches to FreeSWITCH on the private network. All calls are coming from a SIP Trunk provider, from the Internet so no NAT on this side. My Hello World scenario is: FreeSWITCH answers the calls, plays a media file and disconnects. Problems: 1) In the INVITE relayed from Kamailio to FreeSWITCH, I can see a Record-Route with the public IP of Kamailio. Hence, the BYE sent by FreeSWITCH is sent to this public IP, rather than going back to the Kamailio path, and the call never gets completed from the caller's point of view. I tried adding record_route() in request_route{} but nothing changes. 2) The SDP part of all the messages coming back and forth from Kamailio and FreeSWITCH all contain the correct private IPs, but still the media file can't be heard on the caller's side. Is RTPengine correctly bridging the RTPs? Kamailio configuration is here: https://gist.github.com/eravelo/b3f026723e27d42354804ef942b34a04 Rtpengine configuration file has: [rtpengine] table = 0 interface = internal/10.20.1.158;external/10.20.1.158!KAMAILIO_PUBLIC_IP listen-ng = 127.0.0.1:2223 timeout = 60 silent-timeout = 3600 tos = 184 port-min = 16384 port-max = 32768 Your help is appreciated. Thank you. Eric R.

received parameter in route URI not used despite path use_received set to 1
by Easy Rider 19 Mar '21

19 Mar '21

Hi I'd like to make sure I've understood correctly how use_received in path module is supposed to work, because I don't get what I expected to get after reading the documentation I've got a little set up with a UAC behind a NAT registering to a kamailio registrar through a kamailio edge proxy (he UAC is a simple sipp script simulating a UAC behind a NAT) path is enabled on both EP and registrar, and use_received is set to 1 on EP the path, contact and via headers in the REGISTER going from the EP to the registrar are : Via: SIP/2.0/UDP 192.168.26.129;branch=z9hG4bK20da.9f4ab6ad25eae6acdd4bd4d655b320ce.0 Via: SIP/2.0/UDP 10.0.0.5:6060 ;received=192.168.26.1;rport=23456;branch=z9hG4bK-105-1-1 Contact: <sip:1000@10.0.0.5:6060>;methods="INVITE, ACK, BYE, CANCEL, OPTIONS" Path: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456> where 192.168.26.129 is obviously the edge proxy then I place a call to the UAC through registrar the EP receiveds the following INVITE : INVITE sip:1000@10.0.0.5:6060 SIP/2.0 Record-Route: <sip:192.168.26.142;lr> Via: SIP/2.0/UDP 192.168.26.142;branch=z9hG4bKdf25.142eebc72e940d07ad983a858c67f64e.0 Route: <sip:inside@192.168.26.129;lr;received=sip:192.168.26.1:23456> Via: SIP/2.0/UDP 192.168.26.1:34567 ;received=192.168.26.1;rport=34567;branch=z9hG4bK-107-1-1 From: "1001" <sip:1001@my-fake-domain.com>;tag=107-1 To: <sip:1000@my-fake-domain.com;user=phone> CSeq: 1 INVITE Call-ID: 1-107(a)192.168.26.1 Contact: <sip:1001@192.168.26.1:34567> ... The Route header is exactly what is expected, but the edge proxy still sends the request to the request-URI address (10.0.0.5:6060) instead of sending the request to the received address set in the first Route header The path module documentation states : 3.1. use_received (int) If set to 1, the “received” parameter of the first Route URI is evaluated and used as destination-URI if present. kamailio configuration on the EP is almost the default one (just added path support, and modified the REGISTRAR route to forward the request instead on saving the contact, so there is not even a mid registrar on the EP tried with kamailio 5.3.7 and 5.4.4 thanks

Kamailio how to make UAC challenge on Dispatcher failure route
by Antonio Couto 18 Mar '21

18 Mar '21

I have one Kamailio that makes an outbound register on two Asterisk. I have a dispatcher with that same two Asterisk destinations, on INVITE message I call replace_from("", ) in order to call a internal extension and on failure route I receive 401 and call the process of authorization is OK. The problem is that if the first Asterisk fail and I get 500 on failure route I can not call replace_from() because is not valid on the block. Is there any way to make this type of authorization process after receiving a 500 on failure route of dispatcher ? Below my cfg file. Thanks in advance.

Hi all, I have one question. What softphones can I use when trying VoLTE (not VoIP) with Kamailio? I would like to verify VoLTE of private LTE with Open5GS and Kamailio. I'm sorry to ask you a question without much understanding of Kamailio, VoIP and VoLTE. Thank you very much in advance. Best regards, --Shigeru

Server requirements estimation
by Marat Gareev 17 Mar '21

17 Mar '21

Hello! I'm configuring Kamailio proxy and trying to find instructions or advises for choosing the following options: *Host specific* - Number of cores - RAM size *Kamailio specific* - Number of children to fork for the UDP interfaces - Shared memory size The proxy will not connect to the database, only route INVITEs using the dispatcher. The expected load is 70K requests per hour. Are there any formulas for calculating the parameters?

sip_trace() in branch_route, kamailio 5.1
by Daniel Donoghue 17 Mar '21

17 Mar '21

Hello, Using kamailio 5.1, I am trying to use sip_trace(<internal-sip-uri>) from a branch route to send a copy of the current sip message to another location. Sending the message works fine but I note that the message being sent is the original incoming request and does not contain what was changed for the particular branch. Is there any way to get sip_trace() to send the content of the message for that specific branch? With every blessing, — Daniel Donoghue

Kamailio how to make UAC challenge on Dispatcher failure route
by Antonio Couto 17 Mar '21

17 Mar '21

I have one Kamailio that makes an outbound register on two Asterisk. I have a dispatcher with that same two Asterisk destinations, on INVITE message I call replace_from("", ) in order to call a internal extension and on failure route I receive 401 and call the process of authorization is OK. The problem is that if the first Asterisk fail and I get 500 on failure route I can not call replace_from() because is not valid on the block. Is there any way to make this type of authorization process after receiving a 500 on failure route of dispatcher ? Below my cfg file. Thanks in advance.

kamcmd dlg.end_dlg not working in shell script

Below I log events of stuck calls and as you can see it just keeps logging the same call until I manually run the kamcmd either in bash shell prompt or in kamcmd cli: 2021-03-08T19:00:04.347807+00:00 sjointgkama51 /scripts/get-call-from-hepic.sh - get-call-from-hepic: Mon Mar 8 19:00:04 UTC 2021 Found active dialog on completed call.

dmq support for all transports - udp, tcp, tls, sctp
by Daniel-Constantin Mierla 16 Mar '21

16 Mar '21

Hello, (cross-posting - notification for developers, but also looking for testing support in the users community). So far dmq had support only for UDP, suitable to use for replication over trusted networks (local private network, or vpn). There were couple of discussions in the past about supporting other transport like tcp or tls. Earlier today I pushed several commits to dmq module trying to remove the limitation on UDP, and support the rest of the base protocols available in Kamailio (TCP, TLS and SCTP). Internally, a significant behaviour change is that the first (startup) peer notification is now done in the SIP worker one process, instead of the main process, in order to have all transports initialized. I could not spot any relevant side effect that can happen based on quick analysis, because the code with UDP only support was sending out the KDMQ requests, the corresponding replies could come back later. Anyhow, if any other dmq developer thinks of something not being quite right, reply to the sr-dev mailing list to discuss further. For users community: it would be appreciated if people using dmq can test with other transports (TLS, TCP, ...) and report any problems on sr-users mailing list or open an issue on bug tracker. Interesting test scenarios would be with replication of large amount of data or high rate of replicated requests per second. My testing got to the level of connecting to peers via TLS, trying to ensure the code is no longer limiting to UDP. I will do more, but I thought of giving a notification in early phase and get some feedback in order to avoid advancing too much in a wrong direction.

Dialog using Recod Route, with an asterisk
by Nicki Otte 15 Mar '21

15 Mar '21

Hi everyone I have a question regarding the dialog module. It uses the RecordRoute header, which seems all fine. The situation: I have a setup, where the Kamailio proxy, which is running with the dialog module, is talking to an Asterisk. Now the logic in the Asterisk, is to place a new call, and return in to the Kamailio proxy, which sends it to the PSTN. By the logic of the asterisk, it doesn’t persist with the RecordRoute headers. It starts from scratch with a new callId. Here lies the problem. Because the RecordRoute header isn’t given, then a new “dialog” is made, instead of using the one that is established. Here comes my question. Is it against the standards to make the Asterisk persist with these headers, or am I looking at the wrong solution? If not, I do see the power of the dialog module, when a call bounces between UAS’, but not when an asterisk is in the setup. Another solution could be to use a custom x- header for the dialog id, but it doesn’t look like that is a possibility. Have any of you run into this situation, and might have a solution? Thanks in advance // Nicki Bo Otte

iOS CallKit and tsilo
by Igor Olhovskiy 14 Mar '21

14 Mar '21

Hello! Is there any way to "store" already finished transactions in tsilo? Idea is to deliver, for example, canceled calls to the phone, when call already was answered on other device, but push notification arrive later? Major problem here, that there how it's working on iOS. On iOS phone first show you calling screen, than - app is waking and after app will register and receive invite with tsilo, it updates calling screen with CallerID and other info. But if call was canceled before, calling screen is shown, but app not receiving INVITE, so, call screen is just there for some timeout (for Linphone, for ex, it's 20 sec). Right now I've manage to do it via external SIPP call, that emulates "fake missed call", but maybe there is other way to "store" already dead transactions for some time? PS: Unfortunately, can't solve this on mobile app level. -- Regards, Igor

Trouble with Kamailio/RTPEngine and NAT/Firewall
by PJ Slauta 13 Mar '21

13 Mar '21

Hi, I have a Kamailio/RTPEngine setup with Asterisk on a couple of EC2 instances. There is a public IP and it's setup to accept any ports from our IP addresses. If I DMZ my machine behind my router, I get audio, otherwise I don't get any audio, but the SIP portion of the call connects properly. It isn't specific to my network either, it's the same for my partner on his network. I'm assuming that NAT is getting in the way, although I'm not 100% if it's that or if it's a problem opening ports. I have tried with SIP/RTP Passthrough enabled without success. Can anyone provide some guidance here? Thanks, PJ Slauta

Open separate TCP streams to the same destination
by Sebastian Damm 12 Mar '21

12 Mar '21

Hi, I have a peer that requests separate TCP connections for each registration to their server. Those registrations run through the same Kamailio instance on my side. Now what I tried is to use tcpops and the tcp_set_otcpid function, supplying a previously nonexistant TCP connection ID before relaying the register request. The command itself returns true, however, it does not do anything. The content of $conid of the reply is something totally different. So I guess, this function only works for already existing connections. Is there another way to explicitly tell Kamailio to open up another connection to a peer even though a connection to that peer is already open? Thanks in advance. Regards, Sebastian

Best way to ignore HTTP requests
by Ben Kaufman 11 Mar '21

11 Mar '21

I've set up a server listening on TCP recently, and notice that I'm receiving intermittent, random HTTP requests from the internet. While it would probably be a good idea to enforce a firewall rule to only allow known hosts to communicate, what would be the best way within Kamailio to ignore http requests? Would just checking $rP work? Regards, Ben Kaufman ben.kaufman(a)altigen.com<mailto:ben.kaufman@altigen.com> Director of Cloud Operations AltiGen Communications, Inc.

Kamailio how to make UAC challenge on Dispatcher failure route
by Antonio Couto 10 Mar '21

10 Mar '21

I have one Kamailio that makes an outbound register on two Asterisk. I have a dispatcher with that same two Asterisk destinations, on INVITE message I call replace_from("", ) in order to call a internal extension and on failure route I receive 401 and call the process of authorization is OK. The problem is that if the first Asterisk fail and I get 500 on failure route I can not call replace_from() because is not valid on the block. Is there any way to make this type of authorization process after receiving a 500 on failure route of dispatcher ? Below my cfg file. Thanks in advance.

limits in hashtable
by Fabian Borot 10 Mar '21

10 Mar '21

Hi I have a hashtable with about 2500 elements in it. Some of the key_names are the same and in the config file and I traverse them using the index. The problem that I am having is that not all the values are loaded into memory. Lets say I have 5 entries with key_name and key_values like this: 1.2.34:5060:10.10.10 --> 0001232555690 1.2.34:5060:10.10.10 --> 0004562555691 1.2.34:5060:10.10.10 --> 0007892555692 1.2.34:5060:10.10.10 --> 0003212555693 1.2.34:5060:10.10.10 --> 0006542555694 when I do this kamcmd htable.get mytable 1.2.34:5060:10.10.10[0] kamcmd htable.get mytable 1.2.34:5060:10.10.10[1] kamcmd htable.get mytable 1.2.34:5060:10.10.10[2] kamcmd htable.get mytable 1.2.34:5060:10.10.10[3] kamcmd htable.get mytable 1.2.34:5060:10.10.10[4] I am supposed to get their values on the console but sometimes I can not get the 3rd or 4th value , instead I receive this error error: 500 - Key name doesn't exist in htable. What I have been doing so far is to delete extra/old keys from the physical hashtable and load the values again and then it works for a few days. But there is a process that adds entries to the hashtable and at some point it breaks again and I have to delete again old/unused ones. I can not use 'expire' here because the time it takes to become "old" is unknown/variable. This is how the table is defined..2^16 is more than enough to hold 2500 values. What am I missing here? modparam("htable", "htable", "a=>size=16;autoexpire=0;dbtable=htable;") I have taken pcap captures between the kamailio server and the db and I see all the values being transferred over the network when the kamailio is loading/refreshing the values from the db. Is there another limit somewhere? Also when I try to dump the values I get 'reply too big'. modparam("ctl", "binrpc_max_body_size", 10240) modparam("ctl", "binrpc_struct_max_body_size",10240) ./kamcmd htable.dump a ERROR: reply too big any assistance is highly appreciated fborot

If I execute "kamctl ul" show I can see the registrations but if I execute "kamctl ul show username" I get "ERROR: domain unknown: use usernames with domain or set default domain in SIP_DOMAIN" I understand I should use domain in case I was using it in the usrloc module but I'm not.

Route - loose_route
by Ilie Soltanici 09 Mar '21

09 Mar '21

Hello, I have a strange issue here with the Route header not been respected by the Kamailio server. I'm getting the INVITE from the SBC-1, adding my own RR header (SBC-2), and send it to the SBC-3 This is the Invite I'm sending outside to the SBC-3 Proxy. ``` INVITE sip:+123456789@192.168.1.1:5060 SIP/2.0 Record-Route: <sip:SBC-2:5067;transport=tls;r2=on;ftag=as2b53df6f;lr> Record-Route: <sip:SBC-1;ftag=as2b53df6f;lr> ``` I'm getting back 200OK with mirrored RR, the call is established successfully. But, the problem is with the BYE message coming from the SBC-3: ``` BYE sip:+123456789@192.168.1.2:5060 SIP/2.0 ROUTE: <sip:SBC-2:5067;transport=tls;r2=on;ftag=as2b53df6f;lr>,<sip:SBC-1;ftag=as2b53df6f;lr> ``` There are 2 routes within a single header. Afaik, loose_function should remove his own Route header (SBC-2) and forward the message to the next Route (SBC-1), or to the URI if there are not other Routes. But, in my case, for some reason Kamailio on SBC-2 is sending the request directly to the URI, bypassing the SBC-1. In the logs I'm getting the following errors: *rr_do_force_send_socket(): no socket found to match second RR (sip:SBC-1)* *rr_do_force_send_socket(): second RR uri is not myself (sip:SBC-1)* To enforce the socket I was trying to use 'sn=interface', then I'm not getting anymore this error - but still, Kamailio sends the message directly to the URI, instead of SBC-1. Is there anything wrong with my config, or I am missing something with the Route headers? Kamailio Version: version: kamailio 5.4.4 (x86_64/linux) bdf4e0 Thank you.

Lookup issue with websockets contacts
by moisesynfante 09 Mar '21

09 Mar '21

I have configured Kamailio for websockets support and I'm having issues whenever I try to lookup a WS registered uac on the location table, it never finds the contact even though the contact is present when I dump the list via kamcmd. This issue only happens with WS, I tested using another user agent with a different protocol and it works fine, not sure if this is related to the fact that WS RURI doesn't really contain the AoR username. The AoR is something like 104-p4f578, but the contact's address stored is something like: sip:f0ck9vph@sjm8i3la4i7n.invalid;transport=ws; -- Sent from: http://sip-router.1086192.n5.nabble.com/Users-f3.html

Hi, I am running kamailio 5.2.6 on centos 8 and openssl 1.1.1c and connecting and using it as a proxy sip endpoints to a legacy PBX over TLS. The connection to the backend PBX is over TLS 1.2 . Whenever kamailio initiates a TLS connection to the PBX, it uses session ID and a random session id . The server side has a bug and cannot handle the TLS session resuse apparently because of some bug/issue in caching the TLS sessions. The renegotiation and session_cache is by default turned off and I also explicitly set to 0 via modparam but kamailio would always send the session ID in the initial client hello and this is causing us trouble. Any help would be greatly appreciated. https://kamailio.org/docs/modules/5.2.x/modules/tls.html#tls.p.renegotiation Regards, RK

Core dumps/crash handlers

For memory bugs like this ... [mem/f_malloc.c:599]: fm_free(): BUG: fm_free: bad pointer 0x1 (out of memory block!), called from tm: h_table.c: free_cell_helper(185) - aborting ... I'd love to see a core dump, but unfortunately the SIGCHLD from the SIGABRT-terminated child is intercepted and leads to a graceful shutdown: [main.c:743]: handle_sigs(): child process 16037 exited by a signal 6 Is there any way Kamailio can be set to dump core when this happens? -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Kamailio and Asterisk in K8s
by H Yavari 05 Mar '21

05 Mar '21

Hi to all, I am going to run multiple Asterisk instances (Pods) in my Kubernetes cluster. I have a stateless Kamailio sip proxy also. We know that K8s can't handle port range for its services, So we have to use host network for Asterisk deployment. But in this mode, Asterisk pods can't connect to other pods through local IPs and you have to add a second network interface to your pods. One solution is using something like Multus that provides multi-home pods. But it has some issue in host-mode! Also, Using media proxy like RTPEngine in front of Asterisk instances doesn't make a change. You have to run RTPEngine in the host mode or just run it on a VM with multiple NIC.What is the practical solution for this scenario? Thank you. BRHossein

RTPEngine control protocol via TCP
by Alex Balashov 04 Mar '21

04 Mar '21

Hi, Recent versions of RTPEngine (9.x+) implemented support for speaking the "NG" wire protocol over TCP, via the `--listen-tcp-ng` option. Does the Kamailio `rtpengine` module support this, and/or are there any plans to? We've run into a few scenarios where very large responses from RTPEngine can't make it back to Kamailio over the UDP protocol due to fragmentation problems in unique network settings like tunnels. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

topos event_route question
by Juha Heinanen 03 Mar '21

03 Mar '21

I tried to skip topos stripping based on R-URI hostpart like this: event_route[topos:msg-outgoing] { xinfo("******** at topos:msg-outgoing with $rd\n"); if ($rd == "example.com") drop; } and got this to syslog: Mar 2 18:35:59 lab /usr/bin/sip-proxy[22441]: INFO: <script>: ******** at topos:msg-outgoing with kamailio.org Where does $rd == kamailio.org come from, since R-URI hostpart of the request does not have that domain? Or is it so that $rd cannot be used in that event route? -- Juha

Hunt groups with alias_db_lookup
by Adam McCarthy 02 Mar '21

02 Mar '21

Hello, I'm currently using alias_db_lookup to map inbound calls from my SIP carrier to internal endpoints e.g., 1NXXXXXXXXX(a)sip.example.com -> alice(a)sip.example.com. This works well, but I would now like to simultaneously call alice@ and bob@, e.g. alias_db_lookup(...) # somehow return alice@ and bob@ append_branch("sip:bob@sip.example.com") as described here: http://kamailio.org/docs/modules/devel/modules/tm.html#tm.serial_forking This is effectively a hunt group, where two users are called and once one user picks up the call, the second is sent a CANCEL. How would I acheive this with Kamailio? Thanks, Adam

Load htable from MongoDB

Hi there, Question: is it possible to load a htable, defined by columns, from a MongoDB collection, when a certain "column" is an object with multiple elements? For example: modparam("htable", "htable", "users=>size=10;dbtable=users;cols='FirstName,LastName,Location:Prefix';") Fails when trying to load the value of Location.Prefix { "FirstName": "John", "LastName": "Doe", "Language" : "en", "Location" : { "Country" : "USA", "City" : "New York", "Prefix" : "+1" } } Thanks in advance.

UAC changing port for same registration
by Michal Popovic 02 Mar '21

02 Mar '21

Hello everybody, let's have a situation where UAC is behind the NAT and router suddenly change the external port. Kamailio in this case creates two location entries one with old port and one with the new one. Now UAC unregister from the new one and old location remains active until it expires and our support system that is listening to locations changes keep the agent online for other services. Is there any way besides the regular OPTIONS ping from UAS to UAC how to solve this issue? Thanks. Michal

event_route when all modules have been loaded?
by Juha Heinanen 01 Mar '21

01 Mar '21

Is there a way to execute event_route when all modules have been loaded and Kamalio is ready to process requests? I found this in core cookbook, but what if there is no udp sip worker processes? event_route[core:worker-one-init] - executed by core after the first udp sip worker process executed the child_init() for all modules, before starting to process sip traffic -- Juha

unsupported sip invite request-uri format ??
by lgl_hust＠sina.com 01 Mar '21

01 Mar '21

In sip register: Request-URI: sip:ims.mnc001.mcc310.3gppnetwork.org , sip register is ok.In sip invite: Request-URI: tel:310010120073501;phone-context=ims.mnc001.mcc310.3gppnetwork.org, return 478 Unresolvable destination .I saw issue #2287 and #1173 . #2287 deals with register, and #1173 has no result.I want to know how to support such RURI in sip invite, does it need a patch in code ? If so , where and how to modified it . Should i modified kamailio.cfg such as bellows ??? I don't know how modified the kamailio.cfg . if (is_method("INVITE")) {$ru = "sip:ims.mnc008.mcc460.3gppnetwork.org"; # rewrite the "Request-URI"$du= "sip:ims.mnc008.mcc310.3gppnetwork.org"; } Thanks

kamailio debug build
by Sergey Safarov 01 Mar '21

01 Mar '21

I looked at Makefiles and can see instruction # WARNING: do not add mode=debug or mode=release anymore in the Makefile, # use make mode=debug all instead. By default Kamailio is compiled with # debugging symbols in all cases (-g) and without optimization (-O0). https://github.com/kamailio/kamailio/blob/master/src/Makefile.defs#L749-L751 I do not understand how properly build Kamailio with disabled optimization. Could you let me know how to use "mode=debug"? Sergey

Parse multiple URI
by Duarte Rocha 01 Mar '21

01 Mar '21

Greetings, I have a Kamailio proxy where i'm doing some operations over multiple History-Infos and they come in two forms : Scenario 1 -> History-Info : URI1 History Info : URI2 Scenario 2 -> History-Info : URI1 , URI2. On scenario 1 i iterate between headers using $(hdr(name)[N]). However, i can't seem to find a similar tool to apply on scenario 2. In the case Kamailio doesn't have it, what would be the best way to iterate the URIS? I was thinking of parsing them using the comma ",", is that safe? Best Regards,

Kamailio 5.4.4 extremely slow carrierroute preloading
by sr.maillists＠gmail.com 24 Feb '21

24 Feb '21

Hi Maillist! Does someone have experience with kamailio 5.4.4 and carrierroutes loading? We have about 50'000 carrierroutes, kamailio 4.3.6 loads them in about 10 seconds. Kamailio 5.4.4 needs about 10 minutes (!) to load the routes if I set the parameter modparam("carrierroute", "fetch_rows", 50000); Withous this parameter, v5.4.4 loads only 2000. - Virtual Machine is an ubuntu 20.04 with all current updates - Kamailio is installed from source - The database is postgres on a separate host I tested this with the same database and same VM, I only recompiled kamailio and made neccessary changes in the kamailio.cfg. In 4.3.6 I disabled the modules tls and jsonrpcs and added the module mi_fifo.so instead. Any Idea where to search? Did I miss something in the update-procedure? Regards Stefan

I am currently running 5.2.5 but couldn't find any variables in core cookbook or psudovar page.

regarding the kamailio.cfg
by Maharana, Kanhu Charana 24 Feb '21

24 Feb '21

Hi, We are getting some issue in the in sip registration. The scenario is like. Device SIP registration successful with kamalio. Device got reboot abruptly. When the device got power and switched on, device sent a sip registration again. This time the registration is failing in the kamalio. Is there any way to handle it, if the registration request received for a device which is already registered, kamalio should release the old context and start a fresh registration. Regards kanhu

Unregister with Multiple Contacts
by Charles Phillips 21 Feb '21

21 Feb '21

Happy Friday! To clean up contacts that have sent requests to unregister (Expires: 0) I am executing the following after a 200 OK response from the upstream server: reg_fetch_contacts("location", "$fu", "un_reg"); xlog("L_INFO", "Removing unregistered contact From: $si To: $tu Ruid: $ulc(un_reg=>ruid)\n"); unregister("location", "$fu", "$ulc(un_reg=>ruid)”); This produces the desired result when there is only one contact per AoR, but when multiple contacts are present, it seems to delete the first ruid (which makes sense as I am only providing the $fu). So, the question, can I select the contact by call-id or some other unique identifier specific to the desired contact that I can grab from the transaction? Reading the reg_fetch_contact and unregister docs, they do not seem to provide for selection beyond uri. - Charles

loose_route() does not find socket by name
by Juha Heinanen 21 Feb '21

21 Feb '21

I'm returning to this thread, since after some more testing, I found that loose_route() does not (at least always) detect that a pair of route headers denotes itself. In config I have defined: listen=tls:192.x.x.x:8005 name "ext_tls" modparam("rr", "sockname_mode", 1) and Route header looks like this: ROUTE: <sip:tenantX.teams.tutpro.com:8005;transport=tls;r2=on;sn=ext_tls;lr;n1;avp=savp;pm=0>,<sip:192.x.x.x:5070;transport=tcp;r2=on;lr;n1;avp=savp;pm=0> Then this code: loose_route(); if ($du != "") { xinfo("Routing in-dialog $rm <$ru> from <$fu> to <$du> based on route uri\n"); } produces to syslog: INFO: Routing in-dialog ACK <...> from <...> to <...> based on route uri -- Juha

Connection between Kamailio and redirect server
by Igor Potjevlesh 18 Feb '21

18 Feb '21

Hello ! I will have to connect my Kamailio proxies to a routing server which will receive INVITE and replies with 302 and a list of a SIP Contact where (gateways, IP, prefixes or whatever we want) the call must be routed to. I'm wondering what would be the best approach to handle with Kamalio those 302 and then proceed with the routing? For the moment, we use to work with carrierroute. But, since the redirect server will take the routing decision, I believe that carrierroute will no be useful anymore. Thank you for your inputs/experience.

Cockroachdb and kamailio 5.4
by Jonathan Hunter 17 Feb '21

17 Feb '21

Hi Guys, Hope all are well? We are looking to implement kamailio with cockroachdb due to the advantages it gives us in terms of postgres management and clustering. I can see from a previous string http://sip-router.1086192.n5.nabble.com/CockroachDB-and-Kamailio-td189233.h… that someone has attempted this and even created their own branch. Has any further work been done on this, and if so has anyone got any advice/tips relating to it? As I am nervous about potentially using a branch and not a general release of kamailio moving forwards. I appreciate you cant support all database types but I would just be interested to hear people’s thoughts on the topic. Many thanks!

pipelimit with a kamailio cluster
by Daniel Donoghue 17 Feb '21

17 Feb '21

Hello, I have 2 stateful kamailio servers that receive incoming requests, load balanced across the 2 servers by our carrier trunk partners (outside of our control). I am looking at putting certain invites from these trunks into pipelimit to rate limit under some conditions but I have some questions: 1. How will pipelimit establish rates when requests can come in to either of my servers? 2. If pipelimit decides it is time to limit the requests, will both servers respect that limit? 3. does pipelimit rely on a db or can it use dmq, redis or other methods for cross-server communication? 4. Is there a maximum number of pipes that can be defined? Hope somebody can help me answer these questions. With every blessing, — Daniel Donoghue

Advice on handling SIP trunk to a Perimeta SBC
by Björn Bylander 16 Feb '21

16 Feb '21

Hi, So I’m tasked with setting up a SIP trunk to a Perimeta SBC (https://www.metaswitch.com/products/perimeta-sbc). Apparently, > Perimeta hides the topology of networks by rewriting or removing topology-sensitive information from SIP messages. By default, your Session Controller will make the following changes to SIP messages. > > The Session Controller generates new dialog identifiers (call-IDs, From tags and To tags) for each side of the call, so that it does not expose information about your core network to your access networks. > The Session Controller strips Record-Route and Route information from the message. > The Session Controller rewrites Contact and Via headers so that the source IP address is replaced with the local address of the outbound adjacency. > The Session Controller replaces the IP addresses in c= lines in SDP with the addresses it has allocated for media forwarding. For more information on this, see Media addresses and gates. My problem is this: When the Perimeta SBC sends its first INVITE (I can't say anything about any succeeding INVITEs yet) it's added a Record-Route header with the "lr" parameter included which, as far as I can see makes Kamailio think it should use loose routing which is all well I think. But when the SBC sends an ACK for the "200 OK" from the Kamailio side it doesn't include any Route headers and I think that makes it hard for Kamailio (at least with the standard script which is basically what I'm using) to know where to relay the ACK, at least it makes the t_check_trans() call in WITHINDLG after 'is_method("ACK")' return false which makes the script ignore the ACK. Any thoughts or suggestions on how to handle this? Thanks in advance, Björn Bylander

Usage of ldap/db2_ldap
by DEV 16 Feb '21

16 Feb '21

Hi! I'm trying to use the ldap / db2_ldap module in kamailio but I'm stuck because the docs seem to either be outdated or me being on the wrong track. >From what I understand, I need a single ldap.conf but there are two example files with different syntax: 1) https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ldap.… 2) https://github.com/kamailio/kamailio/blob/master/src/modules/ldap/etc/ldap.… I'm already using ldap realtime for asterisk and want to switch kamailio to use the same objects by using this schema: https://github.com/kamailio/kamailio/blob/master/src/modules/db2_ldap/ser.s… When using syntax from (1) I receive this error: ERROR: ldap [ldap_mod.c:198]: mod_init(): no section found in config_file [/etc/kamailio/ldap.cfg] I double-checked my conf and it matches (1). When using (2), I got an error, telling me I left some tables unconfigured (even when mixing both syntax). What is the correct syntax to use ldap as my auth module and replace mysql auth tables? Thank you. Kind regards Kevin

Hi, I am running docker with this: https://hub.docker.com/layers/kamailio/kamailio/5.4.3-trusty/images/sha256-… and https://hub.docker.com/layers/mysql/library/mysql/8.0.23/images/sha256-8708… I made some configurations in Kamailio container: /etc/default/kamailio RUN_KAMAILIO=yes USER=kamailio GROUP=kamailio CFGFILE=/etc/kamailio/kamailio.cfg DUMP_CORE=yes /etc/kamailio/kamailio.cfg #!define WITH_MYSQL #!define WITH_AUTH #!define WITH_USRLOCDB /etc/kamailio/kamctlrc SIP_DOMAIN=kamailio.org DBENGINE=MYSQL DBHOST=172.19.0.3 DBPORT=3306 DBNAME=kamailio DBRWUSER="kamailio" DBRWPW="kamailiorw" DBROUSER="kamailioro" DBROPW="kamailioro" DBACCESSHOST=172.19.0.5 DBROOTUSER="root" DBROOTPW="whatever" CHARSET="latin1" USERCOL="user" Then I run creation of database: /usr/sbin/kamdbctl create All was ok so I can see in MYSQL database: +------------------+------------+-----------------------+ | user | host | plugin | +------------------+------------+-----------------------+ | root | % | mysql_native_password | | kamailio | 172.19.0.3 | mysql_native_password | | kamailioro | 172.19.0.3 | mysql_native_password | | kamailio | 172.19.0.5 | mysql_native_password | | kamailioro | 172.19.0.5 | mysql_native_password | | kamailio | localhost | mysql_native_password | | kamailioro | localhost | mysql_native_password | | mysql.infoschema | localhost | caching_sha2_password | | mysql.session | localhost | caching_sha2_password | | mysql.sys | localhost | caching_sha2_password | | root | localhost | mysql_native_password | +------------------+------------+-----------------------+ At this point, if I try to restart kamailio i get an error and container will never go up again, so I had to delete it and restart the whole installation and configuration process.

Any idea on what could be the problem? I tried giving permissions to some folders in Kamailio docker container: chown kamailio:kamailio /usr/sbin/kam* chmod 755 /usr/sbin/kam* chown -R kamailio:kamailio /etc/kamailio chmod -R 755 /etc/kamailio chown -R root:kamailio /var/run chmod -R 755 /var/run chown -R kamailio:kamailio /run/kamailio chown -R 755 /run/kamailio But had no effect...
