Actually i own this server and the software there is opensips :). For the media
relay (audio) i'm using 'rtpproxy' which ineracts with opensips using a socket.

  Not really. You need to ask the people that own that SIP proxy because only
  they can answer you why they do not relay your media. According to the logs
  you sent, their proxy added itself in the path as a media relay, so it should
  be responsible for forwarding your media traffic.

  The only thing you could try is to disable ICE on both ends see if it helps.
  Sometimes the proxy might be dumb and get confused by ICE and do the wrong
  thing. From your logs that proxy didn't handle ICE signaling correctly. In
  the end blink detected that and didn't use ICE, but the proxy/media relay
  might still be confused by its mere presence.

  I believe it to be a problem with your media relay, which seem to be on the
  same system as the sip proxy. Only the owners of that relay can debug your

  As a note, when you're in a call, you can open the chat window and in there
  you have a session info panel that has a traffic graph. In that you can see
  both sent and received traffic. If you see received missing it means the
  traffic is not relayed. If you see received traffic but do not hear anything
  it might be an audio device issue.
