RMX Integration into the Microsoft Lync Server 2010 and
Lync Server 2013 Environments
From Version 7.8, the 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, RMX 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.
Configuring the Polycom-Microsoft Solution
See the Polycom Unified Communications Deployment Guide for Microsoft Environments ,
“Deployment Process for Polycom RMX Systems” for detailed steps on how to deploy a
Polycom RMX system for use with the video conferencing solution in Microsoft Lync Server
2010 environment.
Call Admission Control (CAC)
Microsoft Call Admission Control (CAC), a protocol that enables bandwidth management
via the Policy Server in federated (ICE) environment, is supported on the RMX.
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 RMX. 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.
Guidelines
• 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
— RMX 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 RMX 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 RMX when running Video
Switching conferences.
Non-Lync endpoints connected to the same CP AVC-based conference as Lync endpoints running
on the Collaboration Server, cannot participate in the desktop sharing session initiated by Lync
participants.
