Perform this step only if you are deploying Communications Server with Private Branch Exchange (PBX) integration.

Enabling users for PBX integration means that their calls are managed by both Office Communications Server and their legacy PBX. They can send or receive phone calls using either their desktop PBX phone or Office Communicator. Calls originating in one system are forked to the other, so that all user endpoints are rung. For details about planning for PBX integration, see Communications Server-PBX Coexistence in Select a Deployment Option in Office Communications Server .

To enable users for PBX integration

  1. Click Start, point to Programs, point to Administrative Tools, and click Office Communications Server 2007.

  2. Expand the Enterprise pool or Standard Edition server node where your users reside.

  3. Expand the pool or server where your users reside, and then click the Usersnode.

  5. On the Communicationstab, next to Telephony Settings, click Configure.

  6. If the user is not yet enabled for Enterprise Voice, click Enable Enterprise Voice.

    This activates Enable PBX integration.
