[SR-Users] Kamailio as SBC / LB Media-Servers farm

[davy van de moere]

If you want to have your Asterisks on only private IPs, you will need to
use some sort of RTPProxy, the standard config examples typically work for
that setup.

On the other hand, some people are starting to come back from that topo,
and just use Asterisk (or freeswitch) as the RTPProxy. And perhaps you can
just have your asterisk on a public IP. As the extra security you might
think you have because it has a private IP, is much less then what the
diagram says.

Anyhow all is possible, the beauty of flexibility :)
