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

How to hang up the call in xhttp routing
by mm e 21 Dec '23

21 Dec '23

event_route[xhttp:request] { if ($hu =~ "hangupCall"){ $var(body) = $rb; xhttp_reply("200", "OK", "",""); jansson_get_field($var(body), "callid", "$var(callid)"); jansson_get_field($var(body), "cseq", "$var(cseq)"); if (t_cancel_callid("$var(callid)", "$var(cseq)", "22")) { xlog("L_NOTICE", "t_cancel_callid============"); } exit; } xhttp_reply("404", "Not Found", "",""); exit; } According to this route, the answered call cannot be hung up。How should I hang up the answered call in xhttp routing, similar to freeswitch's uuid_kill。
