Touch Tones
Touch tones, or DTMF tones, are the tones that sound
when you press the keys on your device keypad. You can
use touch tones for many automated dial-up services such
as banking and airlines, or for entering your voicemail
number and password.
Touch tones are sent during an active call. You can send
them manually from your device keypad, or send them
automatically by saving them in your device.
