8 Live signal and notification management
8.1 Introduction
Your handset offers services such as live calls, notification calls, event keys or status calls. These services
must be activated and configured by your administrator. Please contact your admnistrator before using
these services.
Only notification and event calls can be initiated by the user. Live signals and status calls are transparent to
the user as these calls are automatically made by the handset.
• Live signals:
Live signals are calls that are made automatically (every 90 seconds by default) by the handset to
the notification server. The information sent to the notification server allows the server to confirm

• Notification calls:
Notification calls are initiated by the user of the handset. They are used to notify the server of
emergencies such as injuries or material damage when specific keys are pressed. Refer to the
'Notification calls' chapter in the user guide for information on how to initiate a notification call.
• Key event calls:
Key event calls are also initiated by users when pressing particular keys on the numeric keypad.
These are designed to notify the server that certain tasks have been completed, for example, 'room
is ready' in the case of a hotel application.
• Status calls:
Status calls are automatically established by the handset each time the handset is plugged into or
removed from the charger and each time the handset is switched on and off.

situations involve injuries or material damage and have highest priority among all other alarm events and

depend on your system configuration.

user may receive an acknowledgement or in conference message.
