Contrary to popular usage, TOUCH-TONE and DTMF are not the same. TOUCH-TONE is what the keypad on your telephone produces. DTMF is used for sending call information from one central office to another. I guess, since DTMF is used correctly)ly) so frequently to mean TOUCH-TONE, that DTMF will become another Q-tip or Kleenix. By the way, the tones used for DTMF are not the same as the tones generated by your telephone 'dial'.
