kamailio installable on stretch?
by David Villasmil Govea 14 Sep '18

14 Sep '18

Hello guys, is kamailio from deb http://deb.kamailio.org/kamailio51 stretch main deb-src http://deb.kamailio.org/kamailio51 stretch main Installable on debain stretch? I'm getting: # apt-get install kamailio kamailio-xmlrpc-modules kamailio-mysql-modules Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'kamailio-xml-modules' instead of 'kamailio-xmlrpc-modules' Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: kamailio : Depends: libreadline7 (>= 6.0) but it is not installable kamailio-mysql-modules : Depends: libmariadbclient18 (>= 5.5.36) but it is not installable E: Unable to correct problems, you have held broken packages. # but libreadline7 is not avaiable on stretch.

Forward SIP request between two Kamailio servers
by Nathanael Eneroth 14 Sep '18

14 Sep '18

Hi,? I have a simulation setup of 4 VMs in Virtual Box - two UAs and two Kamailio servers. The first UA will register to KAM1, and the second UA will regsiter to KAM2. See the Figure below. UA1<--->KAM1<---->KAM2<---->UA2 int1 int1 int3 int3 int2 int2 I would like KAM1 to forward all SIP requests destined to int3 via KAM2 and vice versa. I am aware of the routing logic in 'kamailio.cfg', but i find rather excessive. Pseudo code of what i'm trying to achieve: if (is_method("INVITE")) { if(dst_ip == int3) set_next_kamailio_server(KAM2) } Or: if (is_method("INVITE")) { if(callee is unkown) ask_kamailio_server(KAM2) } Thanks for all the help

SIP traffic is not processed because TCP socket is died. When i core is generated i can force restart process. But i cannot parse logs to catch such event. May exist other way? Sergey

by Aleksandar Sosic 14 Sep '18

14 Sep '18

Hi all, is there anyone here that has done a performance testing measurements between native kamailio config file and full python kemi instance of kamailio? I've read somewhere that the python kemi code was 30% slower. Why is that and are there any plans on trying to improve the performance of python kemi? Thanks, -- Aleksandar Sosic linkedin.com/in/alexsosic/ mail: alex.sosic(a)evosip.cloud

Crashed drouting
by Евгений Голей 12 Sep '18

12 Sep '18

Good evening. I have errors on the server (kamailio v 5.1.0) "kamailio [30529]: segfault at 0 ip 00007f9c00c29cfb sp 00007fffa9808310 error 4 in drouting.so [7f9c00c26000 + 39000]" which cause the service to stop. Although the drouting module has been used for a long time, this has never happened. This was done after adding the functions of the dispatcher module. What could be the reason ? Example error in system kamailio [20728]: segfault at 0 ip 00007f32c1c8fcfb sp 00007fff78430d00 error 4 in drouting.so [7f32c1c8c000 + 39000] in the logs of kamailio 018-09-08T22: 30: 29.0448 "ALERT: <core> [main.c: 746]: handle_sigs (): child process 10556 exited by a signal 11" 2018-09-08T22: 30: 29.0452 "ALERT: <core> [main.c: 749]: handle_sigs (): core was generated" 2018-09-08T22: 30: 29.0456 "INFO: <core> [main.c: 771]: handle_sigs (): terminating due to SIGCHLD" -- B.R.

remove_hf("Bla") for all requests
by Sergiu Pojoga 12 Sep '18

12 Sep '18

Hi there, Say I need to remove_hf("User-Agent") for all requests, back and forth. So I add it at the top of *request_route *section. However, replies don't seem to be affected by it. Do I really need to arm a *t_on_reply route* for this simple purpose? "Problem" with that is that *route[RELAY]* already has some *onreply_route* block doing things like *NATMANAGE *for some methods and as far as I know - only one* onreply_route* can be armed for a request? route[RELAY] { ... if (is_method("INVITE|SUBSCRIBE|UPDATE")) { if(!t_is_set("onreply_route")) t_on_reply("MANAGE_REPLY"); } t_relay(); } onreply_route[MANAGE_REPLY] { ... route(NATMANAGE); } Any suggestions? Thanks.
