13.3 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.
13.4 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.
13.5 Emergency
State
In case of emergency, the operator is authorized to put the exchange
into an emergency state. In this situation, the exchange properties and
rules as configured for emergency state prevail.
In emergency state, only extensions with the appropriate category will be
permitted to initiate calls. If you have not been assigned this category
and try to make a call, you will not receive a dial tone.
