Appendix I - Polycom Open Collaboration Network (POCN)

Solution Architecture Components

Component	Version	Description
Collaboration Server	7.6 and higher	MCU:
		• Functions as the network bridge for multipoint calls between H.323,
		SIP and TIP endpoints.
		• The Collaboration Server can be interfaced to CUCM using a SIP
		trunk, enabling CTS to join multipoint calls on Collaboration Server.
		Signaling goes through the CUCM while the media in TIP format
		goes directly between the CTS and Collaboration Server.
		• The Collaboration Server must be configured to route outbound SIP
		calls to the DMA.
		• The H.323 Network Service of the Collaboration Server should
		register it's dial prefix with the DMA gatekeeper.
		• When the DMA is not used an Ad-hoc Entry Queue, designated as
		Transit Entry Queue, must be pre-defined on the Collaboration
		Server.
MLA	3.0.3	Multipoint Layout Application
		Required for managing multi-screen endpoint layouts for Cisco CTS
		3XXX, Polycom TPX, RPX or OTX systems.
Endpoints		Telephony, desktop and room systems.
		• H.323 endpoints must register to the IOS gatekeeper.
		• Polycom SIP endpoints must register to DMA as SIP Proxy when
		DMA is used.
		• H.323 endpoints must register to the IOS gatekeeper.
