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.
