Alarm Extension

An extension can be programmed by your system administrator as
an Alarm Extension. A call to an Alarm Extension obtains automatic
Intrusion if the extension is busy. Up to seven calling parties may be
connected at the same time.
From an IP extension you can make calls to an Alarm Extension.
However, the IP extension itself cannot be programmed as an
Alarm Extension.
Emergency mode
In the event of an emergency the operator can set the exchange
into Emergency mode, during which only preprogrammed
extensions are permitted to make calls. If your extension is not
assigned with this category and you try to make a call, you will not
receive a dial tone.
