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.
