Hello Team, I am working for a telecom company and want to use Kamailio for my VoLTE testing. I had earlier used these tools for my VoLTE testing using a Polaris CNE. But i have a requirement to perform SRVCC Handover for CS/CS+PS. will Kamailio support the SRVCC Handover? If supported, can it be possible to share the details ? -- Best Regards, Anwesh Babu T

routing calls based on prefix
by Andy Kama 13 Oct '20

13 Oct '20

Hi All, What is the best way to approach this? example if a call comes into kamailio with a specific number it example to:123456789 it must go to the dispatcher module but if a call comes with any other number it must route to a uac or can you use uac with dispatcher? basically i want to route inbound calls to a dispatcher and calls from that dispatcher out a uac

Re: [SR-Users] Local cache registration

I read again the uac doc and didn’t find a way to perform this using the functions that seems to require credentials that I don’t have on the kamailio host. Is the uac module really designed to perform this operation is that way ?

Dispatcher stops working
by Sergio Charrua 12 Oct '20

12 Oct '20

Hello, Using Kamailio 5.1.6 for load balancing & failover, I noticed that from time to time, and very rarely, the dispatcher module stops dispatching to the Asterisk servers. I have to execute a "kamcmd dispatcher reload" for it to (re)start working. This is my dispatcher.list : 1 sip:10.19.XXX.YYY:5060 0 1 duid=sipgw01;maxload=100 1 sip:10.19.XXX.YYY:5060 0 2 duid=sipgw02;maxload=100 1 sip:10.19.XXX.YYY:5060 0 3 duid=sipgw03;maxload=100 1 sip:10.19.XXX.YYY:5060 0 4 duid=sipgw04;maxload=100 This is my dispatch routes: # Dispatch requests route[DISPATCH] { if(!ds_select_dst("1", "10","4")) { xlog("L_INFO","no destination selected from dispatcher list!"); send_reply("404", "No destination"); exit; } xlog("L_INFO","going to <$ru> via <$du>\n"); t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } # Sample failure route failure_route[RTF_DISPATCH] { if (t_is_canceled()) { exit; } xlog("L_INFO", "Media server $du failed to answer, selecting other one!"); # next DST - only for 500 or local timeout if ( t_check_status("500") || (t_branch_timeout() && !t_branch_replied()) ) { #mark the destination Inactive and Probing ds_mark_dst("ip"); if(ds_next_dst()) { t_on_failure("RTF_DISPATCH"); route(RELAY); exit; } } } I suspect that the ds_mark_dst("ip") command in RTF_DISPACTH is the cause. Is there any think I can improve on this? Or any know bug with the dispatcher in Kamailio 5.1.6 version? Thanks in advance, *Sérgio Charrua*

Logging problem
by Jan Rozhon 12 Oct '20

12 Oct '20

Hi, sorry for quite stupid and newbie questions, but I am out of ideas. 1. On one of my Debian 10 servers I am unable to stop logging kamailio messages to /var/log/syslog. It is funny, because I have 3 more servers where it works but on this one, it doesnt and no matter what I try it still keeps sending logs to syslog (and to the file configured). My related configs: /etc/kamailio/kamailio.cfg log_stderror=no log_facility=LOG_LOCAL7 /etc/rsyslog.conf local6.* /var/log/kamailio/cdr.log local7.* /var/log/kamailio/kamailio.log /etc/rsyslog.d/kamailio.conf if $programname contains 'kamailio' then /var/log/kamailio/kamailio.log & stop /etc/systemd/system/multi-user.target.wants/kamailio.service SyslogIdentifier=kamailio 2. It is probably related to 1. I am unable to get the CDRs logged to anything else but /var/log/syslog. I tried database (nothing) and setting cdr_facility and again nothing. It just keeps sending everything to /var/log/syslog. Related configs: modparam("acc", "cdr_enable", 1) modparam("acc", "cdrs_table", "acc_cdrs") modparam("acc", "cdr_facility", "LOG_LOCAL6") Example output in syslog file: Sep 30 09:21:41 sip2 /usr/sbin/kamailio[1151]: NOTICE: {2 21 INVITE ZPZI7Hqytw} acc [acc.c:279]: acc_log_request(): ACC: call missed: timestamp=1601450501;method=INVITE;from_tag=1GH5hGQxN;to_tag=QwcYFet;call_id=ZPZI7Hqytw;code=486;reason=Busy here;src_user=XXXXXXXXX; Is there something trivial I am missing?

Kamailio Bridge
by conradcordeiro＠gmail.com 09 Oct '20

09 Oct '20

Hello everyone, Please, see this: https://github.com/fredposner/scripts/blob/master/kamailio/kamailio-tls_srt…. I am researching to understand how this TLS-bridge configuration works and have a main question about how passwords are handled in this scenario. If the PBX in the equation requires password authentication, when SIP clients connect to the Kamailio bridge with that username and password, does Kamailio pass through the username and password to the PBX? Many thanks, Conrad

jsonrpcs - safest way to get data
by Ilie Soltanici 09 Oct '20

09 Oct '20

Hello, I'm trying to periodically get all registered contacts from the Kamailio memory in the json format. JSONRPCS module have 3 different types of transport to get this data. I just wonder what will be the safest transport for the Kamailio to get all this data? Because all this data it's not so important, I want to gather it without affecting the main process or with the minimal effect on the Kamailio SIP Processing module. 1. The HTTP transport - very useful, working async, but because it depends on the xhttp module - which works synchronously I'm afraid that for big data with contacts this type of transport can affect the kamailio performance. 2. FIFO - this transport also is very fast, working locally - but it's synchronous, I'm not sure how it will affect Kamailio SIP Processing when the local database will have few millions of users registered. 3. DGRAM - also seems to be very fast, working locally or remotely through the UDP protocol, but again it's synchronous and I'm not sure that this transport is returning any output for the request, I tried - but didn't get back anything, while for changing something it worked fine. Maybe it was a misconfiguration in my config file. What would be your recommendation for this case? Thank you.

Hi all. We want to manage users via dbaliases so that one subscriber can have multiple aliases. We have an internal username in the subscriber table. We authenticate with the internal username, the call goes through with the internal username. Is there anyway to specify: 1. Caller-ID to be the actual email_address (added to subscriber table), 2. Authenticate with dbaliases? Any other thoughts please? Appreciate the help. Best wishes.

403 Not relaying (DNS)
by Justin Bookshar 02 Oct '20

02 Oct '20

Hello, I'm trying to use Kamailio as a proxy and registrar component in our network and I would like to be able to do several things. I have an MCU capable of making SIP calls and using Kamailio as a proxy but it is not able to register with Kamailio. I would like to have Kamailio resolve addresses using its DNS component. I have attempted to do this, but I am getting 403 Not relaying responses when attempting to make calls through Kamailio that require the destination URI to be resolved. I have enabled debug and I don't see anything that would cause this. I have verified our /etc/resolv.conf file. When I use the primary DNS server in the list on an endpoint, I can get the address to resolve and the call completes correctly. I know I have working equipment on each end and the DNS server and URI are correct but going through Kamailio fails for both the MCU and endpoint when using it as a proxy. I have also tried to disable the internal resolver by adding the use_dns_cache=no option to the kamailio.cfg file. This produced the same result but as I mentioned I have independently verified the DNS server so I know the issue is isolated to Kamailio. Is it possible for Kamailio to do this or am I wrong in believing it can? The second thing I would like to do is to route calls to the MCU based on a prefix. I think I roughly have this working by adding a custom routing block to the request_route operation. I would also like to be able to make calls to local equipment that is not registered with the registrar and I am not able to do this either. I get the same 403 Not Relaying error when I attempt to call a local endpoint by IP address through the proxy that is also not registered with the registrar. Any info is greatly appreciated. version: kamailio 5.2.5 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, 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: unknown compiled on 09:56:06 Oct 17 2019 with gcc 8.3.0 Thanks, Justin

Kamailio fails to start when tls module parameter 'config' contains a folder name
by Leonid Fainshtein 02 Oct '20

02 Oct '20

Hi, I am using Kamailio 5.4.1 installed from the packages on Ubuntu 18.04. When I define 'modparam("tls", "config", "<folder>")', Kamailio fails to start: ERROR: tls [tls_config.c:418]: tls_load_config(): cannot make tmp file configrcCczj ERROR: <core> [core/sr_module.c:849]: init_mod(): Error while initializing module tls (/usr/lib/x86_64-linux-gnu/kamailio/modules/tls.so) I checked the tls_load_config() function and found that when a folder is defined in the 'config' parameter, the function tries to open a temporary file in the working directory. I believe that the working directory at that point is the folder where Kamailio was started: /usr/sbin. I succeeded to launch Kamailio in two ways: Method 1: copy 'kamailio' to /tmp and modify kamalio.service accordingly. This experiment result made me think that the working folder is the folder where kamailio is started. Method 2: add Kamailio command line parameter "-w /tmp" (I also tried to define the Systemd 'WorkingDirectory' parameter but it didn't have any effect.) I think that the ultimate solution for this problem is to modify the tls_load_config() function in such a way that it will open the temporary file in a folder that is intended for the temporary files. For example, the /tmp folder in Linux and *BSD systems. I guess that /tmp is a good place in MacOS as well. Best regards, Leonid Fainshtein

TOPOS issue
by David Villasmil 01 Oct '20

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) you need to open the email really wide to see it properly. Anyone ever encountered this?

XHTTP_Prom syntax error with usrloc in Kamailio 5.3
by Tim Unkrig 30 Sep '20

30 Sep '20

Hello hello, I would like to monitor our production kamailio cluster (5.3) with prometheus and I was in the beginning so happy to spot the xhhtp_prom module. But when we enabled it, the output was in view of prometheus malformed in combination with the usrloc module, we got the following output: kamailio_usrloc_location-contacts 0 1597934423943 kamailio_usrloc_location-expires 0 1597934423943 kamailio_usrloc_location-users 0 1597934423943 Prometheus only accepts “_” instead of “-“. So unfortunately I get "strconv.ParseFloat: parsing "-contacts": invalid syntax” on the prometheus primary node, when I activated the scraper. This has been issued in the master branch of kamailio with a sanatize function for that problem. But I would like to avoid compiling modules by myself, because this can be messy from time to time. That´s why my question, is there maybe another way of fixing this? I really appreciate any comments here and thanks for your time, Tim Unkrig

xavu methods equivalent to that of xavp (e.g. xavp_get_child)
by Chaigneau, Nicolas 30 Sep '20

30 Sep '20

Using xavu (now that they have been fixed) in a custom C module, I've noticed that the following methods do not exist: xavu_get_child xavu_get_child_with_ival xavu_get_child_with_sval xavu_serialize_fields Though they are not strictly necessary, it could be useful to add them to Kamailio core. (Possibly with code refactoring, to avoid duplicating whole functions ?) What do you think? Regards, Nicolas.

Computing a time difference when handling a stateless SIP request
by Chaigneau, Nicolas 30 Sep '20

30 Sep '20

Hello, New to Kamailio, first post on this ML. I'll probably ask dumb questions, please bear with me :) Here goes the first one. I would like to compute a time difference (with microseconds precision) when handling a stateless SIP request. I looked into the core functions and modules but did not find anything suitable. Before I start implementing this by myself, I'd like to know if there's a simpler way. Thanks for your help! Regards, Nicolas.

TOPOS issue
by David Villasmil 29 Sep '20

29 Sep '20

Hello guys, I have this scenario where I have an ongoing transaction. I receive a 180 (non 100rel) with some to_tag, which i forward back to the caller. Then I receive an 183 (100rel) which is forwarded back to the caller, who in turn PRACKs it. It is then that Kamailio (apparently) can't match that transaction internally and replies to the caller (the one PRACKing the 183 (100rel)), with 493 FORBIDDEN. I'm attaching a trace flow. (Kamailio is 10.255.0.1) Anyone ever encountered this? Is this valid and should work? Regards, [image: prack.jpeg] David Villasmil email: david.villasmil.work(a)gmail.com phone: +34669448337

websocket transport protocol in Record-Route header
by Juha Heinanen 29 Sep '20

29 Sep '20

No matter if UA uses ws or wss to connect to Kamailio, when K routes INVITE from this UA and record_route() is called, K always adds ;transport=ws parameter to Record-Route URI, for example, Record-Route: <sip:192.168.43.83:7998;transport=ws;r2=on;lr> In this test, Kamailio is listening on that port like this: # SIP over WebSocket listen=tls:192.168.43.83:7998 Why doesn't K in this case add ;transport=wss to the R-R URI? -- Juha

uac_replace_from function
by Ilie Soltanici 29 Sep '20

29 Sep '20

Hello, The uac_replace_from seems not to be working properly in the ver 5.4. This is the header I'm trying to change: *From: "Admin" <sip:+123456789@local.ip>;tag=as11428589* by using this function: uac_replace_from("","sip:+123456789@domain.com"); I'm getting the following header: *From: <sip:+123456789@domain.com35316853757>;tag=as11428589* (Double space in the callerid name, and number appended after the domain) Thank you.

A possibility to disable the topology hiding for some destinations.
by Leonid Fainshtein 29 Sep '20

29 Sep '20

Hi, The 'topos' module has a very useful "event_route[topos:msg-sending]" option that allows very easily to disable topology hiding for ITSPs that requires the real data in the Contact header field. It looks like the feature is not supported in the 'topoh' module (ref. https://kamailio.org/docs/modules/5.4.x/modules/topoh.html). The available 'event_route[topoh:msg-outgoing]' option requires defining the remote server IP address (or a list of addresses in some cases) that is not always convenient. Is there a chance that "event_route[topoh:msg-sending]" will be added? Best regards, Leonid Fainshtein

Received parameter on Via

Greetings, When NAT is detected in my Kamailio, the proxy add the parameter "received" to the Via header which includes the source IP. What is the mechanic or function responsible for this behaviour? Does it come from the NATHELPER module? Best Regards,

Rewrite BYE to Cancel
by Lars Olsson 29 Sep '20

29 Sep '20

hi, I have a Kamailio setup infront of a SIP system that do not handle cancellation of a INVITE correctly. The system sends out a BYE request instead of a Cancel request on non connected dialogs. I am trying to find a way to let Kamailio "translate" the BYE request to a Cancel reqeust for the ongoing INVITE dialog. Alternative if SEMS b2bua can do it, but currently it replies: "not sip-relaying BYE in not connected dlg", and I have not found any obvious way to rewrite it there. Any thoughts. I can not change the behavior of the remote system. Best Regards, Lars

Dialog - timeout for dlg with CallID
by Ilie Soltanici 28 Sep '20

28 Sep '20

Hello, I'm trying to get CDR working in Kamailio by using the acc and dialog modules. Everything seemed to be working fine - until i noticed that for some of the calls the call duration is 0, even if that call has been successfully established and duration was for about a few minutes. In the Kamailio logs I'm getting such errors: WARNING: dialog [dlg_handlers.c:1649]: dlg_ontimeout(): timeout for dlg with CallID '304bad142b50bb3a7a117816439ea3d5' and tags 'as3adde5c7' '7d28152f-e0e3-4bcf-9d5c-21c3723b95c5' WARNING: acc [acc_cdr.c:230]: db_write_cdr(): fallback to dlg_only search because of message doesn't exist. This error I'm getting at about 2 min after the ACK message for 200 OK. I'm not sure that this is related to the dialog timeout, but below you can see the related configuration for the dialog module: modparam("dialog", "default_timeout", 10800) # 3 hours modparam("dialog", "early_timeout", 180) modparam("dialog", "noack_timeout", 90) Unfortunately, I'm not able to reproduce this issue, as that's happening randomly and just a few times per day. On the SIP Level i didn't notice any strange issues. Any ideas why is that happening? Thank you.

Lua kemi-test-suite now availble from luaRocks
by Yuriy Gorlichenko 28 Sep '20

28 Sep '20

Hello Kamailians! I'm glad to announce some updates about the Lua Kemi-test-suite which has been presented on KamailioWorld online 2020 conference https://github.com/ovoshlook/kemi-lua-test-suite There are some important updates that I hope will make your life easier if you use Lua KEMI. - Now (finally!) it is available via LuaRocks. So it is easy to go for now. No more manual source downloads! (this is the main reason I'm writing this message ). - More modules and some core functions have been mocked. It is still a lot of jobs that have to be done but the amount of available mocks is growing. - Added CRASH_PROTECTION functionality. So for now there is a mechanism which is checks if you calling a function with an incorrect amount of params ( see README ). - Extended mocking engine: now it is possible to mock any functions of KSR or third-party modules/libraries: for example, Redis, MySQL, or other connectors calls. P.S. suite still on development and changes from time to time, but published versions are stable and ready to use. P.P.S. Warm welcome to contributors.

Linphone push notifications (iOS) and kamailio
by Jan Rozhon 26 Sep '20

26 Sep '20

Hi, I know this is kind of a wrong forum for this question, but I have got no answer from linphone forum so I am trying my luck here. I have kamailio with pretty much the default config with slight modification enabling me the push notifications for iOS (via curl) and late forking (t_suspend, t_continue). But my linphone on iOS although gets awaken does not present me with the call I am trying to establish. Did anyone of you guys experimented with similar setup? If so, to what degree were you successful and can you share some insights especially on the format of push notification where I suspect my problem to be rooted? Thanks in advance and once again, sorry if I am off-topic too much. Regards, Jan
