Touch tone dialling (DTMF tones)
DTMF (Dual Tone Multi Frequency) tones can be
sent once a telephone connection has been estab-
lished. You need this function to communicate with
touch tone-activated telephone systems (e.g. for
controlling your voice mailbox or when dialling in
remotely to your answering machine).
Touch tone dialling
1. Select "
Dial number
" in the call menu.
The numerical input menu is opened.
2. Enter the digits you want.
Each digit is immediately transmitted as a
DTMF tone.
Combining DTMF tones with a telephone
number
You can use the + and w characters in the numer-
ical input menu to combine DTMF tone dialling with
the entry of a telephone number.
The DTMF dialling digits are appended to
the digits of the telephone number without
any breaks.
+
û To enter the + character, touch and
hold the 0+ symbol in the telephone in-
put menu.
The digits of the telephone number are di-
alled first. As soon as the connection to
the telephone number dialled has been es-
tablished, the DTMF dialling digits must be
w
confirmed again.
û To enter the w character, touch and
hold the * symbol in the telephone input
menu.
The digits of the telephone number are di-
alled first. The PCM then waits until the
connection has been established before
p
dialling the DTMF dialling digits.
The p character cannot be entered in
the telephone input menu. It is, howev-
er, recognised by the PCM if it is
stored in a telephone number on the
SIM card, for example. In this case, the
behaviour of the PCM is the same as
the behaviour for "+" described above.
Establishing an additional call
You can establish an additional call while there is
another call active.
Some mobile phones do not support making
or accepting a second call. In this case, the
"
New call
" menu item is greyed out during an
active call.
