Conference Manager
The Polycom RealPresence DMA system’s Conference Manager facilitates multipoint video conferencing.
A multipoint video conference is one in which multiple endpoints are connected, with all participants able to
see and hear each other. The endpoints connect to a media server (Multipoint Control Unit, or MCU), which
processes the audio and video from each and sends the conference audio and video streams back to them.
Traditionally, such multipoint conferences had to be scheduled in advance, reserving ports on a specific
MCU, in order to ensure the availability of resources. Conference Manager makes this unnecessary.
Conference Manager uses advanced routing policies to distribute voice and video calls among multiple
MCUs, creating a single virtual resource pool. This greatly simplifies multipoint video conferencing resource
management and uses MCU resources more efficiently.
The Polycom RealPresence DMA system integrates with your Microsoft® Active Directory®, automating the
task of provisioning users with virtual meeting rooms (VMRs), which are available for use at any time for
