If you don't already have it... getting something else that is more SIP centric is always a better move.

Do you think/know if the newer Cisco phones 7941/7961 etc are better or are they same cr**?

Ok, I took a look at the logs and I finally found what was wrong. Nowadays, when I look at traces I tend to assume that the fundamentals of SIP are sound and focus my troubleshooting efforts on the trickier parts of the protocol but every once in a while there comes a sad phone implementation that reminds me that I shouldn't make such foolish assumptions... The Route: header that Cisco puts in its ACK is truncated. It must contain the entire Route as set by the Record-Route: header it gets in the 200 OK but Cisco chooses the silently chop it which causes vital information to be missing from the message. The call is then treated as a stale call and the NAT traversal cleanup routine sweeps the media part of the call away after 5 minutes or so. I suggest you use a real phone if you have one.
