24Converged Office component overview

With this solution, you can configure Personal Call Assistant (PCA) on the CS 1000 for each user with this functionality. The CS 1000 configured with the PCA provides number plan translations, Call Detail Recording (CDR) for outgoing calls, and enables telephony features, such as Call forward No Answer to Voice Mail, Attendant Recall, and participation as a client in a Group Call for incoming calls.

With the Telephony Gateway and Services component, you can configure the OC 2007 as a Multiple Appearance Directory Number (MADN) member for users with PCA on the CS 1000. With PCA , calls to a user’s phone number can be presented to both the desktop phone and to the OC 2007 client simultaneously. The user can then choose to answer on the most convenient device.

The ability to connect between computers and phones is not natively provided by Office Communications Server 2007; however, the Telephony Gateway and Services component enables this functionality using the SIP Gateway and Multimedia Convergence Manager (MCM) application. MCM directs calls from an Office Communicator user to the CS 1000 connected to their twinned telephone. Telephony Gateway and Services allows you to originate and receive SIP calls (for example, VoIP and Computer calls) from Office Communicator.

In Figure 6 "Dual forking example" (page 25), OCS Front End (FE) forks the call to the CS 1000. The twin phone rings once and does not send another invite. The same scenario applies to calls originating from the CS 1000, the OCS does not get informed to perform another fork. A new setting is introduced on OCS 2007 server that enables or disables dual forking for each user. Remote Call Control (SIP CTI) is available when dual forking is enabled.
