Daniel Thanks a lot for your response, in my case i don't want to provide so many ips to carriers acl because aws elastic ip are not consistent, that is the reason i wanted to proxy everything trough kamailio, here it is my setup i wont be doing any registration because of my setup does not required it, on hardware i had kamailio forwarding to freeswitch then distributed to asterisk and finish to a sbcswitch which i will be virtualizing on aws.
again thanks a lot for your advice you're the best.

Can anyone please point me on a configuration example for kamailio when it is behind NAT, i need to change the contact ip from internal to external on sdp
you should not need that. Kamailio should do record routing, advertising the public IP, so the signaling from the other side is sent to Route headers, not to Contact address.
Use:
listen=udp:_internal_ip_:5060 advertise _external_ip_:5060
and proxy all media from outside to internal asterisk farm.
Asterisk has support for external IP, so it can advertise that IP in SDP and the media will go directly to the asterisk. Makes no sense to make a user space forwarding with rtpproxy.
Cheers, Daniel
Please any help will be appreciated. most of documentation available is when client is behind Nat but not when Server behind Nat like is the case with Amazon aws vpc instances.
Again thank you before hand.
