Problem with signalling - RTP gets lost! Rtpproxy not working properly? I am absolutely stuck ... cause this happens in a live environement. I have the following situation A calls B over carrier 1 - number is not valid and I get back error 404 from carrier and now freeswitch should play a message saying: "number not valid". But from carrier 1 I get back an RTP stream that is useless [1] - and if the correct streams opens from freeswitch - this does not get back to A [2]. I tested with rtpproxy on Kamailio - and all the rtp streams arrive at the Kamailio - but they cannot be "connected" correctly. I guess the problem is the 183 I get back from carrier 1 - after whitch rtp is opened. Or there is a wrong sdp singallisation if the "correct" stream arrives [3]. Sorry - I cannot get a solution - but I could provide various tcpdumps and pcaps.
