Step 9. Enable Users for PBX Integration (Optional)
Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.
Perform this step only if you are deploying Communications Server with 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 information on planning for PBX integration, see Communications Server-PBX Coexistence in Select a Deployment Option in Office Communications Server.
To enable users for PBX integration
Click Start, point to Programs, point to Administrative Tools, and click Office Communications Server 2007. The Office Communications Server 2007 administrative snap-in shows your Communications Server 2007 topology.
Expand the Enterprise pool or Standard Edition server node where your users reside.
Expand the pool or server where your users reside and then click the Users node.
In the right pane, right-click one or more users whom you want to configure, and then click Properties.
On the Communications page, click Configure.
If the user is not yet enabled for Enterprise Voice, click Enable for Enterprise Voice. This activates Enable PBX integration.
Click Enable PBX integration.
If you want to enable RCC in addition to PBX integration, in Server URI type the URI of the RCC server.
If your PBX is unable to parse the Active Directory Line URI field, you also need to enter the extension associated with each user in the Telephone number box of the User Properties page.
