DTMF Tones
You can use your phone to send DTMF (Dual Tone Multi Frequency)
tones. This feature can be used for a variety of purposes, such as
banking by phone or controlling an answering machine.
Automatic DTMF
You can send DTMF tones during a call. You can send the characters
0 - 9,
*, and # as DTMF tones by pressing the corresponding keys.
The DTMF Pause Function
If you wish to send a code, for example your personal access number, it
might be helpful to use the pause function. Before you make the call,
enter both the phone number and the code, separated by a pause
character.
