DTMF Tone Length
The tone you hear when you press a key on your keypad is
called a “DTMF” tone. Most phone services and answering
machines require the phone to transmit this tone when a digit
key is pressed. This menu setting allows you to shorten or
lengthen the time the tone is emitted. DTMF tones are
transmitted even when key tones are turned off.
