System Architecture - Toshiba STRATA CIX Remote Call Control Administrator's Manual

Overview

System Architecture

System Architecture
The Remote Call Control application enables the Microsoft Office Communications
Server 2007 to communicate with all models of Strata CIX systems. With this
configuration, Office Communicator (OC) users will be able to make and receive calls
via Strata CIX telephones and perform other useful telephony features directly from
the Office Communicator application, such as hold/transfer, etc. Telephony statuses of
Strata CIX users in your Office Communicator contacts are also added to the Office
Communicator to complete its enhanced presence presentation. For example, if one of
your contacts is talking on the telephone, then his presence status will be set to "In a
call" with the icon color red.
These features offer the benefits of Unified Communications and communications
enabled business process integration, resulting in increased employee efficiency and
productivity. Businesses can bring their business processes, team and workgroup
collaboration to a new level with the integration of the Remote Call Control
application with the Strata CIX and Microsoft OCS.
Remote Call Control was the PBX integration mechanism that initially shipped with
Microsoft Live Communications Server 2005 and Office Communicator 1.0.
Microsoft has now extended this integration to OCS 2007 and Office Communicator
2007.
In this RCC integration scenario users can issue commands (e.g. click to call) from
Office Communicator to the Strata CIX system for their telephone extension. Office
Communicator is not acting as a "soft phone" in this scenario, but sending commands
to Strata CIX to carry out actions on the calls routed to the user's extension and
telephone device. The Telephone state is also added to Office Communicator presence
so the status will be set to "In a Call" when the user is busy in a call.
The protocol used for this integration is the CSTA over SIP standard TR/87 supported
by the RCC application. The advantage of CSTA as an integration mechanism is that it
enables a powerful addition to user functionality without having to affect Strata CIX
installation or configuration.
