Testing Voice Functionality
When testing voice it??™s important to understand how OCS will process a call coming from a
Communicator client to the PSTN. In Figure 6.36, you can see how the components connect
and what protocols pass through the OCS environment to complete a call.
Figure 6.36 Enterprise Voice Component Diagram
When you place a call from your voice client to the PSTN, the call will travel through
the OCS environment as follows:
1. The user will place a call from the Communicator client.
2. The server will normalize the number and will check for routing rules based on the
location profi les and the user policy, and then will send the call to the appropriate
Mediation Server.
