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.
To set DTMF tones to be long, short, or off:
Short
sends a short fixed-duration tone for each keypress.
Long
sends each tone for as long as you depress the key.
Short DTMF tones work with most automated systems.
Some systems (such as home answering machines) may
require long tones for proper activation.
