You need to use a STUN server. The SIP part of things is just negotiates the connection. A SIP phone also uses RTP for the media stream and without a SIP-aware firewall you need to let your firewall know to let RTP packats through on the right port. That is what STUN does. Your description seems to match this scenario exactly. I managed to avoid STUN by using Asterisk and IAX (a TCP protocol) to connect SipXPBX through my firewall. So I can't help with the details. -- --gh _______________________________________________ sipxtapi-dev mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipxtapi-dev/
