A feature on the 6757i 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 

expansion module 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 softkey, 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.

Use the following procedure to configure the display of DTMF digits on the IP phone.

1. Click on Basic Settings->Preferences->General.

Note: "Display DTMF Digits" is disabled by default.
