Chapter 4: CS 1000, OCS, and SR4134
integration
The SR4134 and the CS 1000 can interoperate with the Microsoft OCS solution to implement Unified
Communications in the network. Unified Communications provides integrated voice, instant messaging
(IM), enhanced presence, audio-video conferencing, and e-mail. By integrating the CS 1000 with the OCS,
you can add Unified Communications features to your voice network while maintaining your existing CS
1000 voice infrastructure.

The following figure shows a sample network topology. In this scenario, the CS 1000 is located at the

office.
Figure 1: CS 1000, Microsoft OCS, and SR4134 interoperation
From the perspective of the OCS server, the SR4134 is a Basic Media Gateway. To translate between
the proprietary Microsoft OCS network and the SIP and PSTN networks, you must install a Mediation
Server module on the SR4134.
The SR2330 does not support the Mediation Server module. The SR2330 requires an external Mediation
Server as it does not support medium modules.
