As mentioned on GH, you have 1) rtpengine running on a private IP=20
address, so is not directly reachable from the public internet, and 2)=20
an offer from a WebRTC client using trickle ICE, which doesn't provide=20
any ICE candidates, and so that client isn't reachable from rtpengine.=20
Either give rtpengine a public address so that it can be reached from=20
outside, and/or (preferable "and") make sure the trickle ICE fragments=20
being sent by the WebRTC client (usually as SIP INFO) are passed to=20
rtpengine (and hoping that one of the candidates are a public address=20
that is reachable by rtpengine).

Cheers
