Hi,
I'd like to ask whether my situation is normal. During kamailio restart calls are dropped from mediaproxy. Those two programs are connected using kamailio.sock. Why RTP strem is dropped when SIP proxy is restarted? I would expect just undelivered BYE or something.
Thanks for answer,
Efelin

Hi Efelin,
i'm not an expert with mediaproxy, but does the kamailio hold some state that mediaproxy need to proper route the RTP packets? This would explain the behaviour that you observe, as this would probably lost during a restart.
Cheers,
Henning

no, kamailio does not need to maintain any state unless use the engage mediaproxy command in which case i think dialog module is needed. i would stay way of that mode (as well as the buggy dialog module).

even if it needs details from SIP signaling, then it is a bug IMO that media proxy kills the calls. Kamailio recovers the states of active calls upon restart when dialog module is loaded, nothing is lost.
I never used media proxy, but restarts of kamailio when using rtpproxy to relay the rtp does not impact at all the ongoing calls.
Cheers, Daniel
