We would like to use the SBC, between customers and Kamailio. Since we have a few systems behind our kamailio where customers are routed with reverse routing, we want to shield our internal IP addresses.

Hi all,
We have a kamailio installation for our voip system and would like to add a SBC.
Where do you want to have the SBC? Between the customers and Kamailio?
SBC is a shortcut for various functions: NAT traversal, topology hiding,
enforcing security policies, ...
Depending on what you need the SBC for you can use different softwares in different setups.
There's a great tutorial for Kamailio / Freeswitch on the Asipto site:
http://kb.asipto.com/freeswitch:kamailio-3.1.x-freeswitch-1.0.6d-sbc
In this case Freeswitch is used as B2BUA, probably for topology hiding and session control, and also as media server, but not as a typical SBC which is located between the customer and the SIP proxy.
