DTMF tones
The numeric keys of the phone (0 to 9, * and #)
always transmit DTMF tones (Dual Tone
MultiFrequency) also known as “ touch tones ”. DTMF
tones are used by certain telephone services such as
answering machines, pagers, etc.
Rather than keying in a separate code after each of a
series of requests, you can carry out complex operations
in one go.
