14.4 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.
14.5 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.
