Hi, I have a ASA 5505 (S/N JMX1314Z2S4) version 8.2(1) and behind it a third vendor conference server and mcu.
I have configured NAT to the server and mcu with the default inspect feature.
The system doesn't work with sip and h.264. When the server receive the call with h.264 codec, he negotiates to h.263 with the client. The vendor says that the asa doesn't do transversal nat with the sip and h.264, so the server negotiate to h.263 because the fw doesn't support h.264.
Is this true?, my question is, asa does support nat inspect for sip with h.264?, if so, how can I configure it?
