12.8 Using DTMF Tones
You can send numbers to the network as Dual Tone
Multi-Frequency (DTMF) tones during a call. Use
DTMF tones to communicate with automated
systems that require you to submit a PIN code or
credit card number.
12.8.1 Activating DTMF Tones
You can set DTMF tones to Long, Short, or Off:
Short sends a short fixed-duration tone for each
keypress. Long sends each tone for as long as you
press the key. Short DTMF tones work with most
automated systems. Some systems (such as home
answering machines) may require long tones for
proper activation.
12.8.2 Sending DTMF Tones
Using the Keypad
Press the number keys to send the numbers as DTMF
tones during a call.
Note: When sending long tones, you may have to
enter a single short keypress first to put the phone in
DTMF mode.
