Administration
The various deployment combinations and settings within the Deployment Architecture affects the
administration of the system.
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 Using a Polycom DMA System as SIP Peer in the Polycom Unified
Communications Deployment Guide for Cisco Environments .
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 Direct Registration of Polycom Endpoints with the Cisco Unified Communications
Manager Participants in the Polycom Unified Communications Deployment Guide for Cisco Environments .

Telepresence Systems (CTS) Integration Solution Architecture.
Solution Architecture Components
Component Version Description
CISCO Equipment
CUCM 9.0.1 Cisco Unified Communication Manager:
• CUCM must be configured to route calls to ASR/SBC. CUCM must be
configured with a SIP trunk to the Service Provider’s SBC.
• All endpoints must register once with the CUCM
• SIP trunks from CUCM to Polycom system components (eg. DMA) should
be configured with Music on Hold disabled.
