Thank you for your response! If they are both using ICE, I'd like to do nothing but add a relaying candidate on-the-fly. But my question was related to clients doing nothing but STUN and "plain old SDP". There is STUN, STUNbis, RFC5389 - but I did not find anything saying "If you discover being behind a symmetric NAT, do XY". Regards, Thomas -- mail: [email protected] web: http://thomas.gelf.net/
