[SR-Users] Asterisk cluster with Kamailio for load balancing.

[Vitaliy Aleksandrov]

Indeed, this is a very good suggestion.

I can propose a little plan for the first step:
1. Learn how sip registration works
2. Configure kamailio as a sip registrar server.
3. Try to route calls between registered phones.
4. Read about in-dialog requests routing (record_route(), loose_route()) 
and configure calls between connected endpoint in a "right" way.

And if you want to learn mode:
5. Try to handle NAT issues at kamailio (symmetric sip / rtp relay)

Asterisk supports symmetric rtp pretty well, so if you want to route all 
calls through asterisk boxes you can skip rtp relay configuration step.
