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

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.

DMA™ 7000”.
