<div>Hi. Please help.<br>
<span lang="en"><span>We have:</span></span><br>
<span lang="en"><span>1.One server</span> <span>consists of:
CenOS6.5 + Opensips1.7 + MediaProxy2.5<br>
2.One MGW: Cisco AS5350<br>
</span></span></div>
<span lang="en"><span>3.UserID=</span></span><span lang="en"><span>telephone
number and </span></span><span lang="en"><span>registration on
OpenSips </span></span><span lang="en"><span>through MySQL<br>
</span></span><span lang="en"><span>4.Call to</span> <span>PSTN</span>
<span>pass through</span> <span>MGW</span> <span>with prefix</span>
<span>9999:<br>
route[4] { prefix("9999");<br>
rewritehostport("<a href="http://192.168.0.3:5060"
target="_blank">192.168.0.3:<wbr>5060</a>");<br>
if (!t_relay()) { sl_reply_error(); };<br>
exit;}<br>
</span></span> <span lang="en"><span><br>
</span></span> Now, such a scheme works:<br>
<br>
(UAC )---->sip----->Opensips 1.7--->SIP--->MGW
Cisco<br>
192.168.0.65 192.168.0.2 192.168.0.3<br>
RTP---------------------------
<div><wbr>------------------------------<wbr>-->MGW
Cisco-------->PSTN<br>
<br>
In this topology visible<br>
<br>
It's not safe, it's necessary to build a new wiring diagram:<br>
(UAC )--->sip,RTP---->(Opensips---<wbr>>rtp,SIP------>)----->MGW
Cisco--->PSTN<br>
85.85.85.85 (85.85.85.2 192.168.0.2)
192.168.0.3<br>
<br>
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>
