Overview
The Converged Office feature provides interworking between Nortel and
Microsoft products. It addresses the market need of our customers who
want to use Microsoft client software for their multimedia needs while
continuing to use the Business Grade Telephony of the Nortel IP PBX.
The software component introduced to implement this functionality is the
TR/87 Front End application that resides on the Signaling Server.
The same TR/87 FE that supports the Office Communicator client also
serves as a core component of the SIP Contact Center architecture.
From the perspective of the TR/87 FE, all client types are transparent,
whether Office Communicator, a TR/87 session initiated by the Contact
Center Manager server (CCMS), or some other SIP UA.
Within the scope of Communication Server 1000 TR/87 supported services
and events noted in this document, all operations performed on the
telephone are directly reflected in the client and vice versa. Similarly, all
phone restrictions applicable to a physical TN also apply to the soft client
that is issuing commands on behalf of a controlled DN.
