Hi, This seems to be caused by an additional media stream (second m= line) appearing in the answer SDP, which is invalid according to RFC 3264.
I'd like to invite you to try the upcoming new version of mediaproxy-ng instead, which has been renamed to rtpengine: https://github.com/sipwise/rtpengine It's still being worked on (including finalizing the name change), but it should handle those multi-stream cases much better (especially when WebRTC clients are involved), even though I can't guarantee that it will fix your problem in particular, as it's an RTC violation. cheers On 04/02/14 06:27, Olli Heiskanen wrote: > > Hello, > > Thanks Richard, I made a new test and below is the output from > /var/log/messages. > > This is probably a relevant part: > Apr 2 14:10:52 u363id562 mediaproxy-ng[18742]: [oginba5h5r8h1hk3kngu - > ] Got LOOKUP, but no usable callstreams found > Apr 2 14:10:52 u363id562 mediaproxy-ng[18742]: Error rewriting SDP > > Looks like the whole call gets somehow messed up, there are several BYE > messages before I end the call from either side.
