Gateway To Polycom® Realpresence Distributed Media Application™ (Dma™) System - Polycom RealPresence 1800 Administration Manual

Entry Queues, Ad Hoc Conferences and SIP Factories
on the MCU. Once an Ad Hoc conference is started, it becomes an ongoing conference, and is monitored
and controlled as any standard ongoing conference.
An external database application can be used for authentication with Ad Hoc conferences. The
authentication can be done at the Entry Queue level and at the conference level. At the Entry Queue level,
the MCU queries the external database server whether the participant has the right to create a new
conference. At the conference level the MCU verifies whether the participant can join the conference and if
the participant is the conference chairperson. The external database can populate certain conference
parameters.
For more information about Ad Hoc conferencing, see Appendix - Ad Hoc Conferencing and External
Database Authentication.
Gateway to Polycom® RealPresence Distributed Media
Application™ (DMA™) System
Gateway to DMA 7000 enables audio only ISDN-voice, ISDN-video (video endpoints using only their audio
channels), SIP and H.323 calls to connect to the Polycom DMA 7000 via gateway sessions running on the
Collaboration Server. Each Collaboration Server conference acting as a gateway session includes one
connection to the endpoint and another connection to the DMA. The DMA 7000 enables load balancing and
distribution of multipoint calls on up to 10 Collaboration Server media servers.
As part of this solution, the Collaboration Server acts as a gateway for the DMA that supports H.323 calls.
The ISDN-voice, ISDN-video or SIP endpoint dials the virtual Meeting Room on the DMA via a special Entry
Queue on the Collaboration Server.
Gateway functionality is not supported by Collaboration Server (RMX) 1800 with no DSP cards.
