DTMF

Acronym for Dual Tone Multi-Frequency, also known as Touch Tone. It is a method, used by the telephone system to communicate the pressed keys when dialing. Each key represents a digit or a character and generates two distinct tones - a high frequency tone and a low frequency tone – when pressed. DTMF allows navigation of voice menus and other advanced calling services. It is also used for control purposes, such as an automatic bill-paying service, or remote control of appliances, such as a telephone answering machine.
