Dialling options
The KEYPAD function allows you to control certain services by entering sequences of
characters and digits.
The KEYPAD function must be set when connecting your Gigaset CX203/253isdn to an
ISDN PABX or to a telephone exchange (e.g., Centrex) which uses the KEYPAD protocol
for control. The digits/characters 0–9, *, # are sent as keypad information elements.
Please inquire of your service provider about which information and codes you can
transmit.
If your Gigaset CX203/253isdn is integrated in a Centrex system, the following
performance features can be used.
Setting options
You can switch between the settings Standard dial (factory setting), Auto keypad and
Dial * and #
.
Standard dial
Once Standard dial has been activated, * and # are not transmitted during dialling, and
if * and # are entered it is not possible to switch to the keypad.
Auto keypad
Once * or # has been entered, this setting automatically transfers ringing during dialling
to the keypad. This automatic switchover is needed for giving commands to the
exchange or PABX.
Dial * and #
Once Dial * and # has been activated, the * and # characters are transmitted during
dialling as commands to the exchange or PABX.
Regardless of the setting options above, after dialling or during the conversation, the
phone switches automatically to tone dialling (DTMF), e.g. for remote control of an
answering machine.
