The UAC can now register to the sip server but obviously no audio connection can be established because RTP is over UDP (filtered by the firewall). Now I have to study if it exists an audio stream format over TCP...

I don't think you really want to use TCP for realtime traffic. But IMHO the more difficult part will be to find UACs/UASs which support this.

We have an user that is behind a firewall that blocks all UDP traffic so we had to use SIP over TCP.

For the audio streams, I don't know if there is a standard protocol over TCP, but anyway it must be feasible because Skype works for him...
