Try to remove the public IP from your Asterisk Box, this will even provide additional security. Then install RTPEngine, configure the RTP Engine accordingly, setup NAT to your Kamailio configuration and try. the following URLs are very good info on how to integrate everything: http://www.evaristesys.com/blog/server-side-nat-traversal-with-kamailio-the-...

Hello I'm trying to run Kamailio in front of an asterisk server due to security issues. Both servers have a public ip address. It works fine but the RTP voice traffic goes directly from the VOIP client to the asterisk server without going through the kamailio server. I want to shut down the asterisk server so that it only talks to the kamailio server.
UA -> Kamailio public IP addr <-> Asterisk public ip addr
How do I force RTP traffic to go through kamailio. Apparently I don't have NAT so I don't need rtpproxy. But you need something that relays RTP traffic? If anyone has an idea I'll take it. Thank you for your help. Hugues.
