Hi,

I'm sure there are a lot of discussions about it here, so don't shoot me 
on this.

What must be Contact address if SIP client is behind NAT and it uses TCP 
or SSL ?
The problem i see:
SIP server never can't establish connection to SIP client, so server 
must use active TCP connection. No problem with that, but again  Contact 
here turns to be useless in that case.

With UDP simple, you STUN public IP end point and use it in contact ... .

Any comments are welcome.
