PSTN Dial-in Using GK Prefix

When connecting to an Collaboration Server 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 Collaboration Server whether the Collaboration Server 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 Modifying System
The following table summarizes the PSTN participant's DTMF input depending on the flag value.
