[reSIProcate] Setting the contact?

[Christian_Gavin at logitech.com]

Hi,

I figured out how to use my own socket for resiprocate. Now how do I set
the Contact: field in all outgoing SIP messages to be my public IP and
external port discovered with STUN, instead of internal IP and local port?

If I access the contact header field and change it before sending the
REGISTER message, it works but only for the first message and not in
subsequent retransmissions (eg. registration with auth credentials).

What is the proper way to do this?

Thanks!
