Automatic Dial String Generation; Pstn Dial-In Using Gk Prefix - Polycom RMX 1500 Administrator's Manual

Automatic Dial String Generation

The administrator can now configure the Gateway Profile to automatically generate and
forward the dial string from the RMX Gateway Session to the DMA in order to connect to the
required DMA Meeting Room. When this configuration option is selected, the participant
does not need to interact with the IVR Service.

PSTN Dial-in Using GK Prefix

When connecting to an RMX that is standalone or part of a DMA solution deployment,
PSTN participants are prompted by an IVR message requesting the Destination Conference ID
followed by the # key to be entered using the DTMF input keypad.
Including the Gatekeeper Prefix in the DTMF input string enables PSTN participants to use
the input string when connecting to an RMX whether the RMX is a standalone MCU or part
of a DMA solution deployment.
Enabling PSTN dial-in using GK prefix
The feature is enabled by the USE_GK_PREFIX_FOR_PSTN_CALLS System Flag in
system.cfg. For more information see "System Configuration" on page 19-4.
