Hi :
 
I have a flow     UE  -> gateway (use openser and runs  proxy mode) ( ip : 192.168.1.2) -> SIP Proxy ( ip: 192.168.1.3),
                         
if i have two user , UE1(192.168.1.5) and UE2(192.168.1.6) send REGISTER request to SIP proxy through gateway,
 
but our gateway add a   maddr = "192.168.1.2"  string in contact header,so the contact in REGISTER becomes  <username@ host ; maddr="192.168.1.2">.
 
now , if UE1 send INVITE message to UE2,  how does sip proxy to do if receive INVITE message?  it will send invite message to UE2 through  gateway ( maddr parameter) ?
and  does openser  has support maddr in contact or not  . thx.
