Hi,<div><br></div><div>Kamailio is definitely the exact tool for this purpose, I have exactly the same setup running as yours and for scalability we started using Kamailio in front of our asterisk servers. Long story short, read these articles.</div>

<div><br></div><div>Once after setting up the environments you don't need Public IPs on your asterisk servers. Just only for Kamailio server(s)</div><div><br></div><div>Regards,</div><div>Sammy.<br><br><div class="gmail_quote">

Hello,<br>
<br>
We have been using Asterisk for sometime and over the last year have started hosting instances for our clients on a vmware platform. These virtual pbx are located on public ip addresses and each customer has their own SIP trunk arrangements with various providers. We have decided to pool our resources and would like to start aggregating traffic.<br>
