Hi<br><br>A quick question, when I apply a fix_nated_register() to a remote user when he/she registers, how can I know later on if this user is behind NAT ?<br><br>All my calls go through a B2BUA: <br><br>Caller ------&gt; kamailio/rtpproxy ------&gt; B2BUA ------&gt; kamailio/rtpproxy ------&gt; Callee<br>

<br>When my B2BUA calls a user, I want to know if this user is behind NAT or not. For now all the calls go through rtpproxy but I would like to apply this path only when user is behind NAT.<br><br>Regards,<br>Pascal<br><br>
