14.2 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.
14.3 Authorization Code
The authorization code is used for applying a certain authority level or
class of service to the phone. Without such a code, the phone can be
used only at the lowest level of the system.
