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 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.
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 handset in DTMF profile.
