If you do not want to be reached, you can use the call protection feature to block your tele-
phone for internal and external calls (e.g. because you don't want the phone in your nursery
at home to ring at night). You can of course still make calls from your telephone in this status.
(As-delivered, call protection is deactivated.)
Activating/deactivating call protection:
An external subscriber cannot reach an extension that has initiated call protection. Internal
subscribers, on the other hand, can get around call protection in case they have to pass on
important information.
If you hear an engaged tone after punching in an internal extension number and you still
want to reach the extension, punch in another digit to initiate a priority call.
Initiating a priority call:
If your modem or your answering machine, for example, answers a call that is intended for
you, you can take this call by punching in the calling number of the corresponding device
and then another digit to connect to the calling party. You can of course also take a call from
any other extension if you think this is sensible. Once you have picked up the call, the sub-
scriber at this extension hears the engaged tone. The other party must have allowed call
pick-up (see Chapter Setting Up Various Pieces of Equipment (Quick Configuration) on
page I-40 in the Installation and Configuration Manual and in the user program).

By means of a priority call, an internal subscriber can still call a call-protected exten-
sion.
For general information on programming by telephone and the tones that are issued in
this connection, refer to Page B-5.
When you call a call-protected extension, you hear the engaged tone.
