Suppress DTMF Display
This feature allows the suppression of DTMF display when a number is dialed during
an active call. When the Suppress DTMF Display is disabled, and you press number
keys during an active call, the IP phone displays each digit as dialed in the LCD
interface. When the Suppress DTMF Display is enabled, the IP phone will display “*”
instead of dialed digits immediately in the LCD interface during the call. In addition,
you can enable the Suppress DTMF Display Delay to display “*” for a dialed digit with
a 400ms delay.
