CS 1000, OCS, and SR4134 call flows
Figure 2: CS 1000, Microsoft OCS, and SR4134 sample call flow: OC client to TDM port
The following figure shows the flow for an OC client call to an Avaya UNIStim phone. In this
case, the OCS server policies are configured to route calls between the branch OC client and
the branch IP Deskphone through the Mediation Server at the main office. As all media from
the branch traverses the WAN, this is not a recommended scenario.
