Hello,<br>
<br>
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.<br>
<br>
Cheers,<br>
Daniel<br>

don't want to provide so many ips to carriers acl because aws

i wont be doing any registration because of my setup does not
required it, on hardware i had kamailio forwarding to freeswitch

<br>
</div>
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.<br>
<br>
Use:<br>
<br>
<div>listen=<a moz-do-not-send="true">udp:_internal_ip_:5060</a>
advertise _external_ip_:5060 <br>
<br>
</div>
<div class="im"> <br>
<blockquote type="cite">and proxy all media from outside
to internal asterisk farm.</blockquote>
</div>
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.<br>
<br>

<div>most of documentation available is when client is

the case with Amazon aws vpc instances.</div>
