Hi Bogdan,
Can you give us some example? 
I use opensips with rtpproxy. but when I use the topology_hiding(), dialogs not matched and OK with SDP not received to the call party and media path not established.
Thanks so.

Best Regards,

The best options for you is to use dialog module with topology
        hiding. This can be easily combined with any of the media relays
        (rtpproxy or mediaproxy) for hiding the media path.

If you have any particular questions on the setup, I will try to
        help you.

Best regards,

Hi. Please help.
We have:
1.One server consists of: CenOS6.5 + Opensips1.7 + MediaProxy2.5
2.One MGW: Cisco AS5350
3.UserID=telephone number and registration on OpenSips through MySQL
4.Call to PSTN pass through MGW with prefix 9999:
route[4] {      prefix("9999");
      rewritehostport(" 5060");
      if (!t_relay()) { sl_reply_error(); };
 Now, such a scheme works:

(UAC       )---->sip----->Opensips 1.7--->SIP--->MGW
------------------------------ -->MGW Cisco-------->PSTN

In this topology visible

It's not safe, it's necessary to build a new wiring diagram:
(UAC      )--->sip,RTP---->(Opensips--- >rtp,SIP------>)----->MGW

        Cisco--->PSTN                    (   

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