In this article we extend the Kamailio IMS platform (as described here) with the NAT traversal capabilities with the help of the PCSCF and RTPproxy server. The RTPproxy will be installed on the same machine as the PCSCF is running. From the performance point of view you may install rtpproxy on any machine which is reachable over IP.
In our labs we have two IMS domains installed, one is OpenIMScore based, another is using Kamailio IMS components. We are trying to make interdomain sessions to test basic reachability. We provide call flows captured for interdomain call session establishment and the call flow established during sending of a file .
Testing the basic Kamailio IMS setup, as it is described in Installing base Kamailio IMS platform on the debian squeeze - 32bit. We are using test1.local zone, where pcscf.test1.local, scscf.test1.local, icscf.test1.local and hss.test1.local are used.

This guide describes the base component installation only. The platform is using four virtual machines, one for each IMS component (PCSCF, SCSCF, ICSCF, HSS).
