Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide

Polycom, Inc.

From Version 7.8, the RMX interoperability level with Lync 2013 is identical to Lync 2010. 

Lync 2013 is backward compatible with all RMX Lync 2010 features.
From Version 7.1, MCU systems can be integrated into the Microsoft Lync Server 2010 

(Wave 14) environment.
In the Lync Server 2010 environment, only the Matched URI dialing (using the SIP URI 
address) is available as the call routing method.

See the Polycom Unified Communications Deployment Guide for Microsoft Environments, 

“Deployment Process for Polycom MCU Systems” for detailed steps on how to deploy a 

Polycom MCU system for use with the video conferencing solution in Microsoft Lync Server 

2010 environment.

Microsoft Call Admission Control (CAC), a protocol that enables bandwidth management 

via the Policy Server in federated (ICE) environment, is supported on the MCU.
The Policy server functionality enables the Lync server to manage the bandwidth allocated 

to the Lync client when connecting to another Lync client or a video conference running on 

the MCU. The bandwidth allocated by the Policy server may be the same or lower than the 

bandwidth requested by the Lync client, which is based on the line rate of the conference.

•

Microsoft CAC is available only with:
—

A Lync server (Wave 14) 

—

Call Policy functionality enabled

—

The Call Admission Control enabled for the Lync Clients

—

ICE environment

—

Local network

—

MCU MPM+ and MPMx Card Configuration Modes

•

Microsoft CAC is applicable only to dial-in calls

•

Additional configuration on the Microsoft side is not required. It is based on the 

existing ICE environment configuration.

•

Additional configuration (setting a system flag) may be required on the MCU to modify 

the system behavior when CAC is enabled in a local network; closing the ICE channel 

or keeping it open.

•

Setting an additional system flag may be required on the MCU when running Video 

Switching conferences.

For more details, see "MCU Configuration for CAC Implementation” on page

.

Non-Lync endpoints connected to the same AVC-based conference as Lync endpoints running on 
the RMX, cannot participate in the desktop sharing session initiated by Lync participants.
