        questions:<br>
        1. to hide the network topology from the users (can be used
        dialog module, function: topology_hiding?)<br>
        2. hide RTP traffic to MGW for Opensips-server (can be used
        MediaProxy or rtpproxy)?<br>
        Please, give examples opensips.cfg-file ?</div>
