Polycom RealPresence 1800 Administration Manual page 424

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.

Description
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.
The Cisco Aggregation Services Routers (ASR) Series includes Cisco IOS
XE Software Internetwork Operating System - Gatekeeper.
It controls and manages real-time multimedia traffic flows between IP/SIP
network borders, handling signaling, data, voice, and video traffic.
Polycom Distributed Media Application
• DMA is an optional component but is essential if Content sharing is to be
enabled.
• All SIP endpoints register to DMA as a SIP Proxy.
• DMA should be configured to route SIP calls (with CTS destination) to
CUCM.
• DMA can be configured with a VMR (Virtual Meeting Room). Incoming
calls are then routed to the Collaboration Server.
