Telephone
To send DTMF tones during a call
Dual tone multi-frequency tone system is used by all touch-tone telephones. DTMF
assigns a specific frequency, or tone, to each key so that it can easily be identified
by a microprocessor. DTMF tones allow you to communicate with voice mailboxes,
computerised telephony systems, etc.
To send DTMF tones during a call, you have two methods.
Either,
Tip: Besides the numbers 0 - 9, you can also use the characters p, w, *, and #
when sending DTMF tones. For information on these characters, see ’To store DTMF
tones’ on page 77.
Type the digits with the communicator keyboard. No menu or command button
selection is needed before starting to enter the digits. Each keystroke generates a
DTMF tone which is transmitted while the call is active.
Alternatively,
1 Press Send DTMF. The DTMF sequences you have stored in the contact card of
the person you are talking with are shown. For information on how to store
DTMF sequences, see page 77.
2 Select a DTMF sequence. You can edit the sequence. If there are no stored
sequences, you can enter a new DTMF sequence into the input field.
3 Press Send tone.
Note: You can send DTMF tones during a conference call by typing the digits
with the communicator keyboard, but you cannot access stored DTMF
sequences.
