Dialing To Polycom® Dma™ 7000 - Polycom RMX 1500 Administrator's Manual

Chapter 17-Gateway Calls
Dialing to Polycom® DMA™ 7000
Calling a DMA Direct with Automatically Generated
Destination Dial Strings
17-28
Two dialing methods are available to ISDN/PSTN participants calling the
DMA:
• Direct with automatically generated destination dial strings from
dial-in strings. This option is available only from version 7.1 and only
to RMX with MPM+ and MPMx cards.
• Via Gateway IVR.
In addition, PSTN participants can dial the Gateway IVR and can use the
MCU or DMA prefix in the gatekeeper together with the conference ID/
endpoint alias as the destination string to simplify the input. This is one of
the methods for PSTN participants to connect to a virtual Meeting Room
on the DMA. For more details, see "PSTN Dial-in Using GK Prefix" on
page 17-10.
In this configuration, the gateway session initiator enters one of the dial-in
numbers assigned to the gateway profile. This number is truncated by the
RMX gateway and the truncated digits are replaced by a prefix that
corresponds either to the DMA prefix in the Gatekeeper.
