Yes, good point. But it's really difficult an
scenario in which two
users behind the same NAT connect to different proxies.
In this case the media proxy would be enabled even if not necessary.
Not all relay work if several media proxy are used because some RTP
relay wait for RTP data before relaying and RTP is received on the
other relay....
* What if the
endpoint is detected as a non-symmetric NAT (most
probably, you detect this on SIP signalling port.) but becomes
symmetric on the RTP port?

It sounds really nice.
What I really like is the idea of non-replacing the "Contact" header
in the proxy (described in "outbound" proxy AFAIK).
UA can have correct contact even if not using outbound:
send OPTIONS
check received= and rport= parameter in answer.
send REGISTER with correct contact binding!
easy....
