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.
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 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.
Sending DTMF Tones
Using the Keypad
Press the number keys to send the numbers as DTMF
tones during a call.
To send numbers as long tones, make sure that DTMF is
set to
Long
. During a call, enter any single short keypress
to put the phone in DTMF mode, then send the required
numbers by pressing and holding each key in turn.
