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 DMA/Resource Manager system are not required.
For more information see Polycom Unified Communications Deployment Guide for Cisco Environments,
Using a Standalone Cisco IOS Gatekeeper.
Neighbored Cisco IOS and Polycom Resource Manager/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 Polycom Unified Communications Deployment Guide for Cisco Environments,
Neighbored Cisco IOS and Polycom Resource Manager Gatekeepers.
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 Polycom Unified Communications Deployment Guide for Cisco
Using a Polycom DMA System as SIP Peer.
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
Direct Registration of Polycom Endpoints with the Cisco Unified Communications Manager Participants.
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 DMA/Resource Manager Gatekeeper and the CUCM
for reporting and billing purposes.
Cisco Equipment
To configure the various Cisco entities the following procedures are required.
