Hello everybody, I installed and configured opensips with a residential configuration setting NAT Traversal and Multidomain options with the opensips configuration tool. When I try to make a call with two users, the ACK method of the caller party never reaches the called party.<br>
<br>This are the messages received in the called party:<br><br><br>INVITE sip:ralvarez@domain;transport=udp SIP/2.0<br>Via: SIP/2.0/UDP 10.151.199.52:45084;branch=z9hG4bK-d8754z-06f2fafe119979f6-1---d8754z-;rport<br>Max-Forwards: 70<br>

I need to fix the contact header value because the IP address is behind the NAT and is not reachable from the caller party location. I don't know how to do this, reading some answers in the users mail list i found that setting the global parameter "advertised_address" in the configuration file it will solved it but I'm not sure, can anybody tell me if this is correct?<br>
<br>Thanks for all.<br><br><br>
