DMA
The DMA system can be configured as a SIP proxy and registrar for the environment as well
as a Gatekeeper for dial in H.323 calls. When configured as a Gateway for dial in H.323 calls, it
enables H.323 endpoints to connect to the same VMR as SIP clients.
When used as a SIP peer, the DMA system can host video calls between Cisco endpoints that
are registered with the CUCM, Lync Clients that are registered with the Lync Server and
Polycom 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”.
Microsoft Lync Server
Microsoft Lync Server manages Presence for each registered Polycom endpoint and enables
video calls between Lync Clients and Polycom endpoints allowing Lync contacts to be called
without needing to know their addresses.
RTV video, MS-ICE and Lync-hosted conferencing are supported when Polycom endpoints
are registered to Lync Server. Polycom endpoints use H.264, while Lync Clients use the RTV
protocol.
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 the Polycom Unified Communications Deployment Guide for Cisco
Environments, “Direct Registration of Polycom Endpoints with the Cisco Unified Communications
Manager Participants”.
