public interface for clients and a private interface for media servers and database), using rtpproxy to handle the relaying from public to private network.</div><div><br></div><div>The only problem I got is that called client get the call as it was originated by one of the media server (the call contact is some like <a href="mailto:ext@media.server.ip">ext@media.server.ip</a>), which is wrong in my opinion.</div><div><br></div><div>Here it is the configuration,</div><div>can you help me dealing with this?</div><div><br></div><div>Thank you
