Problem with 4.0 nightlies and IMS - sem_post undefined
by Barry Flanagan 21 Nov '13

21 Nov '13

Hi I am trying to run the Ubuntu nightlies from http://deb.kamailio.org/kamailiodev-nightly and loading the p-cscf config files. Things were working fine while I was on the 20130110 nightlies, but when I upgraded to 20130122 I get the following errors. Any have an idea why sem_post is undefined and how to fix this? 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/ims_registrar_pcscf.so>: /usr/lib64/kamailio/modules/ims_registrar_pcscf.so: undefined symbol: sem_post 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/cdp.so>: /usr/lib64/kamailio/modules/cdp.so: undefined symbol: sem_post 0(1980) ERROR: <core> [sr_module.c:572]: ERROR: load_module: could not open module </usr/lib64/kamailio/modules/ims_qos.so>: /usr/lib64/kamailio/modules/ims_qos.so: undefined symbol: sem_post Thanks -Barry Flanagan

Hello List.

pkg mem problems. Leaking?
by Jon Bonilla 08 Apr '13

08 Apr '13

Hi all I have two different kamailio servers running in a single machine. The first one is a sl proxy and the second one acts as stateful proxy/registrar. From time to time the stateless one goes out of pkg mem. It has 8MB (also tried with 16 in another setup). The sl proxy listens the public interface for external connections and the loopback interface for conecting to the stateful proxy. As I have seen since I installed a mem debug kamailio 3.3.2 version there 6 days ago, the internal socket children have grown on mem usage while the external ones remain more or less stable. As example one uf the external udp receivers uses less than 1MB while one of the internal ones uses almost 6MB. I'm attaching the mem dump of one of those internal udp receiver processes via "ngcp-sercmd lb cfg.set_now_int core mem_dump_pkg 25437" command. I see several tens of thousands of lines like these ones: N address=0x7fd1207383c0 frag=0x7fd120738390 size=56 used=1 alloc'd from <core>: parser/parse_param.c: parse_params(539) start check=f0f0f0f0, end check= c0c0c0c0, abcdefed I have no idea about how to continue debugging this. I'm pasting some more info regarding the process list, mem status and kamailio version/flags.

Kamailio not increasing cseq
by Camila Troncoso 19 Mar '13

19 Mar '13

Hi all, I’m working for a while with Kamailio+Freeswitch as SBC. I have this structure: * * * * * * * * * * * * * * * * * * When I make a call from one client connected to LCR, it is route to my SBC and afterwards to his destiny in the cloud passing though a gateway. When the destiny is unreachable, the LCR reroutes the call to another gateway. Sometimes the LCR send this retry again to the SBC , because the second gateway is also in the cloud, but when this happens, FreeSWITCH answer with : “482 Request merged” because it detects that is the same call. This is because the second INVITE has the same Call-ID and same Cseq. Kamailio *is not* increasing CSeq. Is there a way to resolve this? Regards, *Camila Troncoso **|* Ingeniero de Desarrollo RedVoiss *|*ctroncoso(a)redvoiss.net Santiago - Chile *|* +56 2 2408535 www.redvoiss.net

Kamailio only allowing traffic with machines in the dispatcher.cfg?
by Benjamin Henrion 16 Mar '13

16 Mar '13

Hi, Does someone know/uses a simple rule so that Kamailio only exchanges traffic with machines in the dispatcher? Best, -- Benjamin Henrion <bhenrion at ffii.org> FFII Brussels - +32-484-566109 - +32-2-3500762 "In July 2005, after several failed attempts to legalise software patents in Europe, the patent establishment changed its strategy. Instead of explicitly seeking to sanction the patentability of software, they are now seeking to create a central European patent court, which would establish and enforce patentability rules in their favor, without any possibility of correction by competing courts or democratically elected legislators."

Need help understanding/separating signaling from media
by Grant Bagdasarian 13 Mar '13

13 Mar '13

Hello, I want to separate signaling and media in our architecture but I'm not entirely sure if the following will work (note that it is still in a design phase and these kinds of constructs are still new to me): User Agent 1-------------- Kamailio -------------- User Agent 2 | | | | | | -------------- Media Server Cluster -------------- The signaling will go through Kamailio but the media stream should pass through one of the media servers in the cluster for each call. Is it possible to achieve this by having Kamailio instruct the media server which ports to open and alter sdp information? I think that the RTP Proxy module does precisely this, but what I still don't understand is how the rtp stream is passed between these two agents for each call. Also, is RTP proxy the best way to do this or are there any other third party media servers which I could use? I don't need any fancy functionality, just basic media handling/pass-through. Regards, Grant

Send Bye to all calls in one profile
by Camila Troncoso 13 Mar '13

13 Mar '13

Hi, I have a kamailio proxy server that´s controlling the limit of calls that clients can make with profile grouping. In other side I also limit clients call duration base on users credit ( DATABASE) and *timeout *feature . Before the calls get answer I calculate how much time the client has left for this call and set the timeout variable. When the time is reached the proxy sends BYEs two both sides of this call. I want when the call timeout, as before explain, all other calls in the same profile end too, because the client has expired his credit. Is there a way to achieve this?
