Activating/deactivating DTMF mode
You want to be able to use your phone to control other equipment or to access certain
services, such as remote polling of an answering machine or telebanking. For these
services you need the DTMF mode.
In the DTMF mode each keystroke generates a tone. If for example you enter a call
number during a call, your call partner will hear the tone signals.
You can specify whether the DTMF mode should be generally activated or deactivated
(see chapter
, page
). DTMF is activated as the default
dialling mode.
If the DTMF mode is generally deactivated, you can activate it and deactivate it again
temporarily during a call.
Making a call on a third-party phone
You want to make a call on a third-party phone using your personal settings, for exam-
ple on a colleague’s phone or in a meeting room.
You can activate a third-party phone to make an internal or external call using your
personal settings, even if the phone is locked for external calls.
You can activate the phone for a business or private call.
Once you have activated the phone using a */# procedure and your PIN, dialling by
your private phone book is available.
The called party's display shows your personal phone number and not the number of
the phone from which you are making your call.
Any call charges incurred will be charged to you.
