[SIPForum-discussion] About Header Contact

[Francesco Paolo Landolfo]

Hi,
I have the following doubt.
Suppose that you have two client:

   - A (sip:a at mydomain.org);
   - B ( sip:b at mydomain.org).

Suppose you have a Sip Proxy Server too.

I want to setup a call session using Sip Proxy Server. (Please see the
attached file)

When B sends 180 RINGING back to the client A, does it writes in the Contact
header its sip address  (Contact: "B" < sip:B at mydomain.org>) or its address
of care (Contact: "A" <sip:B at 100.101.102.103>) ???

What is the standard method?

Thanks,
Francesco Paolo Landolfo
