[OpenSIPS-Users] Contact list in REGISTER response

[Bogdan-Andrei Iancu]

Be careful about the expires value - the usrloc module will choose an 
expire value based on the received expire and the max_expire (module 
param). You need to send back to the UAC exactly the same expire as the 
own determined by usrloc, otherwise the server and client will be out of 
sync from expiration point of view. Like the uac will think it is still 
registered, will the proxy will expire the UAC's contact.

Bogdan
