Additional Features
Display DTMF Digits
A feature on the 55i phone 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 softkey or programmable 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 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.
