22Converged Office component overview

Remote Call Control with SIP CTI (TR/87)

The CS 1000 and OCS 2007 integration feature allows clients of the two systems (Microsoft OCS 2007 and Nortel CS 1000) to communicate with each other. You can associate an OC Client, which connects to the OCS, with a CS 1000 line. You can perform operations on the CS 1000 line through the OC Client using Remote Call Control (RCC) often referred to as Phone-Mode. This feature allows for consistent access to RCC, service control and configuration and telepresence functions across different endpoints supported by the CS 1000.

The Nortel Converged Office Solution is implemented through an open interface to ensure that any CS 1000 feature supported through OC 2007 is also accessible to applications from other vendors and application developers who support these interfaces.

The SIP CTI (TR/87) protocol is on the CS 1000 Signaling Server. OC 2007 uses the TR/87 specification to implement phone integration throughout the suite of Microsoft Office applications. You cannot use Office Communicator to invoke a feature that is not supported by the phone.

Example of RCC with SIP CTI (TR/87)

Figure 5 "Remote Call Control with SIP CTI (TR/87)" (page 23) shows an example of a CS 1000 call to a mobile client. The following steps correspond to the numbers in the figure:

1.A user selects Call to Chris’ mobile phone number from the CS 1000 telephone.

2.The Office Communications Server 2007 sends a call request to the CS 1000.

3.The CS 1000 sets up a call from the user’s phone to Chris’ mobile phone number.

4.Chris answers his mobile phone and a media path is established between the two phones.
