NATed solutions with no RTP proxies will depend on the client side, not on the server side like in Kamailio. Key things to notice: 1 - Private IPs (RFC-1918) will always be proxied if you don't change the basic template config;2 - Dual NIC servers require a little bit more knowleadge on Kamailio before you can get it to work properly;3 - Although you can use some tricky configurations, Kamailio is not a SBC like Asterisk/Freeswitch; Having said that, RTPproxy is just good. I mean, it is really good! If it is not working, then you probably have another problem. So the questions are: Are you running your system on virtual machines? What is your topology? How many NICs do you have? Your Kamailio server is connected direct to the Internet or behind a firewall? All the above questions can strongly affect the quality of your calls. Cheers!

Thanks All, Yes, please if you've an example using nathelper without rtp proxy let us know. now more than ten days I am trying to get kamailio up & running to bypass NAT & firewall blocking but I couldn't. After some research I might create a VPN. so please if you have any working example for NAT and Firewall let us know.
