Calling the RealPresence DMA via Gateway IVR
Audio PSTN/ISDN calls can be routed to Polycom DMA 7000 via the Collaboration Server. ISDN Video
endpoints connect using their audio channels (but consume video resources). The RealPresence DMA
system enables load balancing and the distribution of multipoint calls on up to 10 Polycom 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 PSTN or ISDN endpoint dials the virtual Meeting Room on the DMA via the Gateway Profile on the
Collaboration Server.
Both the Collaboration Server and the RealPresence DMA must be registered with the same gatekeeper.
The dialing string of the destination conference on the RealPresence DMA must be communicated to the
dialing endpoint and used during the connection to the Gateway Profile on the Collaboration Server. There
are two options available for doing this:
Manual Dial String Entry
Automatic Dial String Generation
Manual Dial String Entry
Dialing String and Call Flow from ISDN Endpoint to Polycom DMA
The connection is done in two steps:
A PSTN/ISDN participant dials the dial-in number assigned to the Gateway Profile (5705555),
including the country and area code (if needed) and connects to the Gateway IVR.
When prompted for the target conference ID, the caller enters the string of the target meeting room
on the DMA followed by the # key.
PSTN participant dials (212)5705555
Number that will be used by Collaboration Server to forward the call to the DMA 265555
