from the display, the extension is unlocked
12.2.2.5 Changing the Authorization Code

To change the individual authorization code for an extension, do the
following:
1) Dial *74* previous authorization code * new authorization code #.
2) When you hear a verification tone, the individual authorization code
has been changed.

12.3 Alarm Extension
An alarm extension is assigned characteristics similar to an alarm
centre. All calls to such an extension are automatically granted intrusion
access if the extension is busy. Up to seven callers can be connected to
the alarm extension at the same time.
An alarm extension cannot be assigned to an IP phone, but it is possible
to call an alarm extension from an IP phone.
12.4 Direct In-dialing
Direct In-dialing is a feature that enables direct routing of incoming
external calls to predefined extensions or groups. Usually, the exchange
has a direct in-dialing feature, enabling external subscribers to call you
directly without having to go through the operator.
Note: A call that is not serviced by a predefined extension can be
rerouted to an operator or an alternate answering position.
