Seems like the NAT traversal is just broken. just some basic rules:
- Call fix_nated_contact only for request from the clients (although it shouldn't hurt if you call it for all requests) - Whenever a message contains a session description call force_rtp_proxy(). Make sure to provide proper flags regarding the direction of the message. E.g. start rtpproxy listening to internal and external IP and provide the flags "ie" for requests from internal->external and "ei" for requests from external to internal.

Thanks Alex for actually finding the thread for me- I'm reading these thoroughly and let me try these. Klaus, mhome=1 is a good tip let me try it now: The problem is that when I set-up the scenario as I mentioned using Private IPs the end user starts sending the media to the private IP of asterisk (which is of-course not found anywhere near UAC) - The Asterisk Server on the other hand sends media to the Public IP of the Client(fixed by the NAT route and RTPproxy route automatically.) What I've figured out theoretically is that i need to do the NAT address fixation in on-reply route from Asterisk servers. By fixing the c= header in Kamailio for the 200OK back to the client will make the Client software send media to the Kamailio/RTPproxy port and not on some private IP. I hope I made some sense in what I wrote, do let me know if any clarification is required. I'm just this one step away from publishing the setup on blog to benefit the community so any help from experts will be much much appreciated.
