Chapter 4-Entry Queues, Ad Hoc Conferences and SIP Factories

Gateway to Polycom® Distributed Media Application™ (DMA™) 7000

Gateway to Polycom® Distributed Media Application™ (DMA™) 7000 enables audio only PSTN, ISDN (video endpoints using only their audio channels), SIP and H.323 calls can connect to the Polycom DMA 7000 via gateway sessions running on the RMX. Each RMX 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 the distribution of multipoint calls on up to 10 Polycom RMX media servers.

As part of this solution, the RMX acts as a gateway for the DMA that supports H.323 calls. The PSTN, ISDN or SIP endpoint dials the virtual Meeting Room on the DMA via a special Entry Queue on the RMX.
