This Suppress DTMF Display feature allows the IP phone to suppress the display of
DTMF digits. When enabled, the digits you dial using the keypad or a DSS key display
as ―*‖ on the LCD screen. This feature is disabled by default (displays DTMF digits). You
can enable the Suppress DTMF Display Delay feature on the IP phone to display the
dialed digits for a short period before displaying as ―*‖. This feature is disabled by
default (directly displays as ―*‖).
Note The Suppress DTMF Display Delay feature works only if the Suppress DTMF Display
feature is enabled.
