Re: [Kamailio-Users] another instance of kamailio on the same machine >

Hello Juan, On Wed, 1 Apr 2009 06:35:35 -0700 (PDT) Juan Perez <jperezsip2008(a)yahoo.com> wrote: > > we will use a different machine but we are limited with hardware now so in the mean time [and not for production traffic] we need to use the same hardware for > more than one instance to test some stuff > thank you guys If you look at a clean way to have multiple kamailio instances in one physical server, you should look at linux-vserver which work great under debian (http://wiki.debian.org/LinuxVserver) This will allow you to have separate environment for each instance with different IPs and no overhead. We use it for a long time now without problem. Don't hesitate to contact me if you need more informations. Regards, -vma .

[Kamailio-Users] remove_uri_param(param)?
by jh＠tutpro.com 01 Apr '09

01 Apr '09

siputils has function uri_param that can us used to check if r-uri has a given parameter. how about a function remove_uri_param(param) that would remove from r-uri the given parameter? does any efficient (non regex) means exist to achieve it? -- juha

[Kamailio-Users] Processing ACK.
by Carlos A. Alvarez 01 Apr '09

01 Apr '09

I am having an issue while setting up Kamailio. I using the carrierroute modules to process calls between carriers. The configuration works great. However I have and issue. On the SIP messages We are forcing all the media through an RTP proxy, however my issue has to do with the Contact field on the Message Header. While I am able to use force_rtp_proxy to replace the contact and connection fields on the SDP part of the message, I can seem to modify the Contact on the Header part. I tried using subst to change the Contact:, and while I was partly successful, it seems the ACKs going from one carrier to another are getting messed up and throwing Kamailio into a loop. We are trying to avoid providing Contact: information to our carriers. Basically keeping them from know about each other. Any ideas/help will be Greatly appreciated.

[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

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
