Hello,
it is still one IP from point of view of signaling (SIP). Do you want to
provide single IP also for media (RTP)? If you have lot of calls, then
it can result in a bottleneck for bandwidth as all voice/video streams
end up on the same server.
Cheers,
Daniel

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.

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.
