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.<br clear="none">
<br clear="none">
If you have any particular questions on the setup, I will try to
help you.<br clear="none">
