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. 14.6 General Deactivation General deactivation enables you to cancel features using one single command.
