administration of the system.
Gatekeepers
Standalone Polycom CMA/DMA System as a Gatekeeper
The Polycom CMA/DMA system can be used as the only gatekeeper for the network. Bandwidth and call
admission control of endpoints registered with the CMA system is split between the CMA system and the
CUCM.
For more information see the Polycom Unified Communications Deployment Guide for Cisco Environments.
Standalone Cisco IOS Gatekeeper
The Cisco IOS Gatekeeper can be used as the only gatekeeper for the network if the management
capabilities of the Polycom CMA system are not required.
For more information see the Polycom Unified Communications Deployment Guide for Cisco Environments.
Neighbored Cisco IOS and Polycom CMA/DMA Gatekeepers
Neighbored gatekeepers make it easier to create a common dial plan and should be considered when
integrating an existing Cisco telephony environment with an existing Polycom network. Neighbored
Gatekeepers allow number translation while maintaining the existing environments.
For more information see the Polycom Unified Communications Deployment Guide for Cisco
Environments,DMA
The Polycom DMA system can be configured as a SIP proxy and registrar for the environment. When used
as a SIP peer, the DMA system can host video calls between Cisco endpoints that are registered with the
CUCM and Polycom SIP endpoints that are registered with the DMA system.
For more information see the Polycom Unified Communications Deployment Guide for Cisco Environments.
CUCM
When Polycom SIP endpoints (voice and video) are registered directly with CUCM you can take advantage
of supported telephone functions. CUCM may not support the full range of codecs and features available
on the Polycom equipment. CUCM supported codecs and features will be used in such cases.
For more information see Polycom Unified Communications Deployment Guide for Cisco Environments.
Configuring the Cisco and Polycom Equipment
MLA (Multipoint Layout Application) is required for managing CTS 3XXX layouts whether Polycom TPX,
RPX or OTX systems are deployed or not. MLA is a Windows® application that allows conference
administrators to configure and control video layouts for multipoint calls involving Polycom Immersive
Telepresence (ITP) systems.
Call Detail Records (CDR) are generated on both the CMA Gatekeeper and the CUCM for reporting and
billing purposes.
