<P><FONT face=Verdana size=2>Right, in the "200 OK" request the Contact as the private IP address.</FONT></P>
<P><FONT face=Verdana size=2>I register with a domain name so I guess the same domain name as to be set in Contact so I was expecting :<BR>- > Contact: <sip:778@10.0.1.71:33802;rinstance=8572c408a8cc28e3>.<BR>should be replaced by :<BR>- > Contact: <sip:778@osip.dev.com:33802;rinstance=8572c408a8cc28e3>.</FONT></P><FONT face=Verdana size=2>
<P><BR>I have fix_nated_contact(); both in ROUTE and in REPLY_ROUTE the make sure it is always executed, I understand it correctly<BR>1.6.1. fix_nated_contact : "Rewrites Contact HF to contain request's source address:port" </P>
<P>In my case Opensips will need a domain name to find that the target is registered localy, how should I handle this, register with an IP ?</P>
