Kamailio IMS

Extending PCSCF of the Kamailio IMS platform with NAT traversal

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.

Extending IMS base platform with simple Presence service build over Kamailio AS

In this article we describe how to extend the base Kamailio IMS platform (as is described here) with simple presence service realized over Kamailio SIP server.

Testing IMS interdomain session

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 .

Kamailio IMS - Base configuration testing

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.

Installing base Kamailio IMS platform on the debian squeeze - 32bit

This install guide is based on the official install guide from http://www.ng-voice.com/our-solution/installation/

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

Deployment OS is debian squeeze, 32 bit (because only 32 bit packages are available, 64bit have to be compiled).
