[Serusers] Running multiple instances of rtpproxy? How to set up in SER?
by Frank Durda IV 01 Apr '09

01 Apr '09

I have reached the point where a single instance of rtpproxy is about maxed-out, showing that its single process is comsuming 85% or so and climbing of the CPU available. That works out to about 600 standing calls, the bulk of which are G.711. This is a multi-processor/core system and I have several other CPUs not really doing anything, so I would like to start up multiple instances of rtpproxy, which rtpproxy says it can do, controlling them via AF_INET sockets instead of the default AF_UNIX. How you set up rtpproxy for multiple instances seems reasonably straightforward, but what you do on the SER side to let it know that these additional copies of rtpproxy exist and how you or SER divides call load between them is less clear. Is there any documentation or examples showing this done, or better still, someone with a working ser.ctl file who would be willing to show at least that part of their configuration? Ideally, I'm looking for a case where calls are divided among rtpproxies regardless of where they came from or where they are going, as I have one particular call source/destination pair that is absurdly large compared to all others, and that so it in particular has to be distributed across across multiple rtpproxies. Thanks in advance!

[Kamailio-Users] Force core dump
by catalina oancea 01 Apr '09

01 Apr '09

Hello Can anybody please help me on how to force a core dump if a child crashes? I see this: /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: child process 12379 exited by a signal 11 /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: core was not generated /usr/sbin/kamailio[12328]: INFO:core:handle_sigs: terminating due to SIGCHLD /usr/sbin/kamailio[12393]: INFO:core:sig_usr: signal 15 received And if I run with gdb, it says 'Program exited normally' Has anybody managed to make a core dump in this case? Thanks Catalina

[Kamailio-Users] sanity module trouble
by kokoska rokoska 31 Mar '09

31 Mar '09

Hi all, due to malformed INVITEs I'm receiving from clients I like to use sanity module. But after few test I'm affraid I don't understand correctly how it works :-) 1. I try to load the module: loadmodule "sanity.so" modparam("sanity", "default_checks", "999") and kamailio rejects config with the: ERROR:core:set_mod_param_regex: parameter <default_checks> not found in module <sanity> 2. When I comment out "modparam", kamailio starts successfuly, but: All INVITEs (from all clients) are reject through this snippet of code if (method=="INVITE") { if (sanity_check("128")) { xlog("L_ERR", "bad INVITE SDP body length from $si:$sp\n"); exit; } else if (sanity_check("1024", "7")) { xlog("L_ERR", "malformed INVITE from $si:$sp\n"); exit; } } I don't think that all of them could have bad length on SDP body (about 120 diffenet UAC types), so I assume I use "sanity" wrong way... Could you, please, shed some light to proper usage of sanity module? Thank you very much! Best regards, kokoska.rokoska

[Serusers] Network Monitoring
by Bill McNamara 31 Mar '09

31 Mar '09

We are running SER 2.0.0 under RedHat 4.5 (kernel 2.6.9). Anyone have any recommendations for network traffic analyzers, hardware or software, so we can monitor SIP traffic? We would like the solution to be able to detect dropped calls, generate statistics and possibly debug active connections. A Google search returns many hits, but I'd like to get some recommendations from folks actually running the monitors before I start looking at trial versions. Thanks, Bill

[Kamailio-Users] Issue with Carrierroute in 1.4
by Uriel Rozenbaum 30 Mar '09

30 Mar '09

Guys, I'm getting this error on the logs for failure route but just for some of the calls I pass. If I call afterwards to that number it rings OK, so it is a random event: ERROR:carrierroute:cr_load_next_domain: during set_next_domain_recursor, prefix '1054111547533610', carrier 2, domain 1 I'm filling carrierfailureroute with an empty string when I want taht route to be the final one; is it OK to do that? Thanks in advance, Uriel
