Introduction 
This guide describes deployment options for the Polycom CX5000 Unified Conference Station when used 
in conjunction with other Polycom video systems. As a Polycom-branded version of the Microsoft® 
RoundTable™ collaboration and conferencing device, the CX5000 is optimized for use with Microsoft® 
Office Live Meeting 2007 and Microsoft® Office Communications Server 2007. Because of integration 
between the Office Communications Server environment and a variety of Polycom visual communications 
environments, the value of the CX5000 may be extended beyond a pure Microsoft environment to a 
number of scenarios involving Polycom video systems and endpoints. 
This document identifies and illustrates several key scenarios for interoperability between the Office 
Communications Server environment and the Polycom visual communications environment and the 
Polycom CX phones for Office Communications Server.  The scenarios range from basic with audio only, 
to advanced with a mix of audio, video, content and escalation (seamless transition) from audio to video. 
This document does not attempt to address all possible options; once the basic scenarios are described 
and understood, they may be used as building blocks upon which more complicated scenarios may be 
built.   
Scope 
This document is intended to be a descriptive guide. The successful integration of Microsoft and Polycom 
products relies on a variety of skills and knowledge of both companies’ products. There is a vast amount 
of material available that describes the implementation details of Office Communications Server and its 
associated applications. This document assumes that all basic setup and deployment of Microsoft 
systems is described in Microsoft materials, and is not the subject of this document. 
Polycom CX5000 and Microsoft RoundTable Equivalence 
The Polycom CX5000 is functionally identical to the Microsoft RoundTable device. In this document, any 
comments about the CX5000 apply equally to the Microsoft RoundTable device. For any environments 
that may contain legacy Microsoft RoundTable devices, these may be treated as CX5000 devices for the 
purpose of integrating with Polycom systems.
