by Will Ferrer 22 Dec '14

22 Dec '14

Hi All We recently discovered that our dispatcher boxes have this error constantly at the end of our calls. ERROR: dispatcher [dispatch.c:1402]: ds_load_remove(): cannot find load for (<callid goes here>) We aren't seeing any issues arising from it that we can notice but wanted to see if any one knew what it meant and what it might cause. Thanks much in advance. All the best Will Ferrer Switchsoft Inc

rtpengine stats
by Marc Soda 22 Dec '14

22 Dec '14

Does anyone know how a can get stats from rtpengine? I see the $rtpstat pseudo variable in Kamailio, but from the documentation it looks like that will only give me stats on a particular call. I'm looking for overall stats like concurrent calls, bandwidth, etc... Thanks, Marc

Hi there, We haven't used gdb on Kamailio yet but some time soon we'll most likely will. Obviously I'll post our findings. Thanks again! Cheers, Kees On 17-12-14 12:00, sr-users-request(a)lists.sip-router.org wrote: > did you get a core dump file? If yes, send the full backtrace taken with > gdb.

kamailio dispatcher module stops processing REGISTER
by José Seabra 22 Dec '14

22 Dec '14

Hello there, I'm doing stress testing against kamailio (sip load balancer role) sending sip registrar, my stress test software is sending 50 registrations per second, after 30 seconds and 1000 registers processed the function ds_select_dst (I'm using algorithm 4) returns null for all registers sent from my software, and all registrar sip servers are available and in active mode, if I reduce the software to send 20 registrar's per second, the issue only happens after 60 seconds and kamailio (sip load balancer role) process 4000 registrers, after this, function ds_select_dst starts returning null Anyone has any idea why it is happening? My kamailio version is 4.2 Best Regards -- Cumprimentos José Seabra

Initial REGISTER request/response in 3rd Party Register
by jyaim 19 Dec '14

19 Dec '14

Hello, I'm using Kamailio with a SIP Application Server, when a user registers on the IMS Core a 3rd Party REGISTER request is sent to the application server to start some logic. I'm trying to add in the 3rd party register request body the initial REGISTER request sent by user device, and the 200 OK response sent back by Kamailio. Do you think it is possible to configure Kamailio to get this behaviour ? Thank you!
