Chapter 4-Entry Queues, Ad Hoc Conferences and SIP Factories<br />

Gateway to <strong>Polycom</strong>® Distributed Media<br />

Application (DMA) 7000<br />

4-12<br />

Gateway to <strong>Polycom</strong>® Distributed Media Application (DMA) 7000<br />

enables audio only PSTN, ISDN (video endpoints using only their audio<br />

channels), SIP and H.323 calls can connect to the <strong>Polycom</strong> DMA 7000 via<br />

gateway sessions running on the <strong>RMX</strong>. Each <strong>RMX</strong> conference acting as a<br />

gateway session includes one connection to the endpoint and another<br />

connection to the DMA. The DMA 7000 enables load balancing and the<br />

distribution of multipoint calls on up to 10 <strong>Polycom</strong> <strong>RMX</strong> media servers.<br />

As part of this solution, the <strong>RMX</strong> acts as a gateway for the DMA that<br />

supports H.323 calls. The PSTN, ISDN or SIP endpoint dials the virtual<br />

Meeting Room on the DMA via a special Entry Queue on the <strong>RMX</strong>.<br />

For more information, see Appendix H, “Gateway to <strong>Polycom</strong>®<br />

DMA 7000”.
