>> I think in your situation, it can be that your phone first will send RTP to mediaproxy-relay first, then it decides to make a P2P connection and success, then it will uses the P2P and don't send anything to relay anymore, that make relay release the session and close your call. The solution is not using engage_media_proxy, instead using use_media_proxy/end_media_session

I managed to catch (and hopefully fix!) the bug. We tested it and it works, but some extra testing would be nice. You can find the patch attached, which can be applied against the 2.6.0 release.
