Additional Features
Display DTMF Digits
A feature on the IP phones allows users to enable or disable DTMF (dual-tone multi-frequency)
digits to display to the IP phone when using the keypad to dial, or when dialing from a
programmed key.
DTMF is the signal sent from the phone to the network that you generate when you press the
phone’s touch keys. This is also known as “touchtone” dialing. Each key you press on your phone
generates two tones of specific frequencies. One tone is generated from a high-frequency group of
tones and the other from a low frequency group.
If you enable the Display DTMF Digits parameter, the digits you are dialing from the keypad or or
from a programmable key display to the IP phone’s LCD display. This parameter is disabled by
default (no digits display when dialing).
You can enable the "Display DTMF Digits" parameter using the Aastra Web UI.
