Calling The Dma Via Gateway Ivr - Polycom RMX 1500 Administrator's Manual

Calling the DMA via Gateway IVR

Manual Dial String Entry
Example:
Figure 1 shows the call flow assuming the following parameters:
First Dial-in Number
Last Dial-in Number
Use Dial-in Numbers as Destination ID
DMA Meeting Room ID
Destination Prefix (DMA prefix in Gatekeeper)
Number of Rightmost Digits to Append
PSTN participant dials
Number that will be used by RMX to forward
the call to the DMA
Audio PSTN/ISDN calls can be routed to Polycom DMA 7000 via the
RMX. ISDN Video endpoints connect using their audio channels (but
consume video resources). 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 or ISDN endpoint dials the virtual
Meeting Room on the DMA via the Gateway Profile on the RMX.
Both the RMX and the DMA must be registered with the same gatekeeper.
The dialing string of the destination conference on the DMA must be
communicated to the dialing endpoint and used during the connection to
the Gateway Profile on the RMX. There are two options available for
doing this:
• Manual Dial String Entry
• Automatic Dial String Generation

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.
