The various deployment combinations and settings within the various Deployment
Architectures affects the administration of the system.
Standalone Polycom CMA System as a Gatekeeper
The Polycom CMA 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, “Using a Polycom CMA System as a Gatekeeper”.
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, “Using a Standalone Cisco IOS Gatekeeper”.
Neighbored Cisco IOS and Polycom CMA 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, “Neighbored Cisco IOS and Polycom CMA Gatekeepers”.
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, “Using a Polycom DMA System as SIP Peer”.
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 the Polycom Unified Communications Deployment Guide for Cisco
Environments, “Direct Registration of Polycom Endpoints with the Cisco Unified Communications
Manager Participants”.
