It seems very much like an RTP handling problem. Near the problematic place I see RTP sequence number wrap from 65535 to 0. This may be the cause of problem. I recommend you to look into MprDecode flowgraph resource - here is all decoding is done. It is located in sipXmediaLib in src/MprDecode.cpp. I could also recommend you to try patch I've posted to " Silence on Windows Minimise / SipXmedia MpdSipxPcma::decodeIn fun ction drops RTP Packets" thread recenty. -- Regards, Alexander Chemeris.
