Hi,All,
    This is my case:

UAC<--------------------------------------------------------------------------->SIP
Proxy<------------------------------------------------------->UAC
    INVITE
 INVITE
    From: <sip:123456 at 192.168.10.188>                      From: <
sip:123456 at 192.168.10.188>
    To:<sip:6543d21 at 192.168.10.188>                          To:<
sip:6543d21 at 192.168.10.188>
    Contact:<sip:333333 at 192.168.10.188:5060>            Contact:<sip:????@
192.168.10.188:5060>

   So, I want to ask what can my sip proxy can set in "Contact" header?
   and my sip proxy is statefull.

   Best Regards!
