It is Dual Tone MultiFrequency, also known as a Touch Tone. The tones generated by touching the keys on the phone are used for a variety of purposes including voice mail systems and voice messaging. when u call an automated service and a voice responds "press 1 for menu, 2 for operator", ur key press signal is transmitted because of DTMF.
