Re: add a SIP custom header on a SIP response generated locally
by frédéric Gaisnon 18 Jan '24

18 Jan '24

Hi, Yes I've tried using append_to_reply() in several routes (tm:branch-failure, sl:local-response, tm:local-response, onreply_route, failure_route) but it was not applied. It works fine if a response is received or if it is generated by the configuration script but not if this response is locally generated by a kamailio module. Regards, Frédéric Gaisnon > Custom headers to the reply can be added using append_to_reply() function from textops module.

trigger different branch route on branch added with append_branch
by Benoit Panizzon 18 Jan '24

18 Jan '24

Hi List Imagine the following situation: Two Kamailio registrar proxies handling the same domain. Location Information synced via DMQ. So if a device registers we don't know on which of the two registrar proxies. Core proxy is dispatching calls to either one of those registrars. Core also performs AOR database lookup and adds an X- header telling which AOR the call is destined to. Registrar performs lookup of that AOR in the location database and routes the call to destination. Problem: The call could be routed to the the registrar which does not hold the active socket to that client. Solution: reg_fetch_contacts, cycle the contacts and append_branch if the contact has a local socket. Next Problem: I use a failure_route to sent the call to voicemail, if not registered, busy etc. This would trigger, if we have no local socket for the registration which is on the other registrar. So I have to find a way to send the call to the other registrar. I guess I can append_branch a branch pointing to the URI of the other registrar. This would then succeed in reaching the device. Also using the failure_route would work this way if we get a remote error from behind the other registrar or no registration at all. Next Problem: I use a branch trigger to remove undesired header I do not want to send to the customer. Now imagine that AOR has two contacts, one on registered on each registrar proxy. So I end up with two destinations added with append_branch to the destination set. One points to the device of the locally registered customer device, the other one points to the other registrar where to find the other device. I use a branch route trigger to remove the X- Headers towards the customer. But I need to X- Header containing the destination AOR to still be sent to the other registrar. Is there a way to trigger a branch route for only some of the destinations added with append_branch? Or to trigger different branch routes for different destinations in one set added with append_branch? Or am I doing this completely wrong and there is an easier way? ;-) Mit freundlichen Grüssen -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________

tls.cfg and configuration
by Aymeric Moizard 17 Jan '24

Hi all, I'm using a central file to define my kamailio cfg configuration. First question: In my main kamailio.cfg, I use: include_file "kamailio-config.cfg" which contains: #!substdef "!MY_DOMAIN!kamailio.example.com!g" I would like to use the same in tls.cfg which is defined this way: modparam("tls", "config", "/etc/kamailio/tls.cfg") but I get: sr_cfg_parse(): tls.cfg:17:1: Unsupported option 'include_file' Would you advise some way to achieve my goal: ie, I would like only one file to edit my configuration options which would have an effect on both kamailio.cfg and tls.cfg Second question: Can someone confirm that #!substdef will also not have any effect when used in tls.cfg Thanks Aymeric -- Antisip - http://www.antisip.com

Not checking SRV records

Hi This may be a stupid question but after a couple of hours and some headache I can't see where the problem is. I'm trying to use SRV records to relay to different servers as I've done many many times before. But in this case I'm getting a 478 from kamailio and I see that it's not trying to resolve SRV.

Internal DNS resolver
by Igor Potjevlesch 12 Jan '24

Hello! I have a quick question about the internal DNS resolver and cache embedded in Kamailio. Is the ability to add an entry with dns.add_a bypass the "real" DNS lookup? So, let's say that sip.example.com is publicly resolve alternatively with 1.2.3.4 & 5.6.7.8.9, if I do a dns.add_a to add my own sip.example.com with, alternatively, 127.0.0.1 and 127.0.0.2, will it work?

Clarification on usrloc timer_interval param and contact-expires event route.
by James Lipski 12 Jan '24

12 Jan '24

Hello, Just need a bit of clarification on the usrloc parameter "timer_interval". Let's say this is configured with a value of 60 seconds; every 60 seconds, will this delete all expired contacts in the location table between runs -- as in between runs it will queue up a list of expired contacts, remove them all after the 60 seconds has elapsed, then execute the event route "event_route[usrloc:contact-expired]"? Or does the event route execute as soon as the contact expires, independent from "timer_interval" timer? Thank you.

Timeout on forwarding REGISTRATION
by dries＠degendt.com 10 Jan '24

10 Jan '24

Hi all, My Kamailio server has been throwing a lot of errors during the manipulation and forwarding of registrations to my Asterisk server (192.168.96.97) using uac_req_send(); and t_relay() [core/tcp_main.c:1402]: tcp_do_connect(): connect 192.168.96.97:5060: (99) Cannot assign requested address [core/tcp_main.c:1399]: tcp_do_connect(): connect 192.168.96.97:5060 failed Cannot assign requested address When looking deeper into the code it appears that the errors are thrown when "tcp_async" is enabled. I've enabled this option a few weeks ago to make sure clients can REGISTER quickly. The parameter "tcp_reuse_port" is also set to yes. I'm suspecting that on busy moments, the destination can't be reached because no TCP connections are available. Is there any of the following parameters that I can adjust to prevent this issue? tcp_children = 25 disable_tcp = no tcp_max_connections = 63536 tcp_connection_lifetime = 3605 tcp_accept_aliases = no tcp_async = yes tcp_connect_timeout = 10 tcp_conn_wq_max = 65536 tcp_crlf_ping = yes tcp_delayed_ack = yes tcp_fd_cache = yes tcp_keepalive = yes tcp_keepcnt = 3 tcp_keepidle = 30 tcp_keepintvl = 10 tcp_linger2 = 30 tcp_rd_buf_size = 80000 tcp_send_timeout = 10 tcp_wq_blk_size = 2100 tcp_wq_max = 10485760 tcp_reuse_port=yes /* tcp_connection_match=1 */ open_files_limit=63536 A quick tcpdump doesn't show outgoing packet during the error events.

Hello, Any idea about the crash below? I found a ticket regarding to this, I made some comments and backtraces there also: https://github.com/kamailio/kamailio/issues/3635 Now this crash is very frequently, 3-4 times every day. There is a timer mechnism, where kamailio refreshes registrations towards asterisk automically to ensure continuous availability for mobile users. The crash exists 3-5 secs after this refresh process, but not always. Sometimes this process runs fine only CRITICAL logs appears (mentioned below) after it, but sometimes kamailio crashes during writing these CRITICAL logs.

Crash of Kamailio when using module http_async_client - function http_async_query, if module "tm.so" is not loaded (Kamailio 5.7.3)
by Chaigneau, Nicolas 10 Jan '24

10 Jan '24

Hello, When using http_async_query function, provided by module http_async_client: https://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#… If module "tm.so" is not loaded, then immediately upon calling function http_async_query, Kamailio crashes: 9(3807541) CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 8 0(3807527) ALERT: <core> [main.c:791]: handle_sigs(): child process 3807533 exited by a signal 11 0(3807527) ALERT: <core> [main.c:795]: handle_sigs(): core was generated 0(3807527) INFO: <core> [main.c:818]: handle_sigs(): terminating due to SIGCHLD Of course, I now know that I must load the module "tm.so". But I think it would be better to catch the issue when Kamailio starts, rather than crashing later on when trying to call http_async_query. What do you think ? Regards, Nicolas.

Hi, Facing the following error after bumping Kam from 5.3 => 5.4 => 5.5 => 5.6, following instructions on each step about DB structure and module changes. These errors show up since. Any clue what they mean? A couple other modules are using the same DB MySQL connector. The data in the DB also seems to get updated properly.

webRTC Test Client?
by Andy Newlands 03 Jan '24

03 Jan '24

Hi, I have a Freeswitch installation, fronted by a Kamailio proxy I would like to configure Kamailio to bridge SIP between webRTC clients and Freeswitch. The first issue I hit is how to set up a test webRTC client to make calls into Kamailio/FS. Can anyone point me to a simple webRTC client I can use to make test webRTC/SIP calls into my setup? Thanks BTW: I'm not JS experienced (I work with Python, C#, C/C++). Kind regards, Andy
