Summary: Registration to Ekiga.net fails

Initial Comment:
The Ekiga.net checks during registration that both the Via and Contact headers 
contain a public IP address. The registation fails with 606 if the Via header 
contains a NATted address from the private address space.

Message:
It shouldn't be an interop problem to put the public transport address in
the client's Via. When the binding breaks, the proxy should signal it with
rport and received which will be different from the address in Via.

Sure, we do the latter, but the ekiga.net proxy rejects this REGISTER with
606 Not Acceptable.

Why do you think this is a sofia-sip problem ?
There is nothing wrong whit that.
Ekiga SIP server will end up sending the response to the udp-src address
ignoring the Via host address.

The UA application must take care of the contact address by:
-Using some kind of STUN mechanism
- Learning from the REGISTER response ( checking the Via parameters ) and
reusing a new REGISTER
- or not taking care at all and failing to get incoming calls.
