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.
13.5
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.
13.6
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.
