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.

Collaboration	8.1.1 and up	MCU:
Server		• 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.

		to DMA.
		• Collaboration Server must be configured to send and receive RTP
		streams to and from the Service Provider's SBC.
