More Features of Your Extension

Your extension may also offer you, depending on your user rights, 

other services that are geared toward improving your productivity, 

securing the use of your telephone, or just making its use even 

more enjoyable.
Within this context, the following services are offered:
•

Locking service: You may lock your extension when you are 

absent, preventing any third party from using it.

•

Appointment reminder service: You may request that the system 

call you at a specified time, in order to remind you of a meeting, 

etc.

•

Background music service: Depending on your user rights, you 

may request that background music be played over your idle 

extension’s loudspeaker.

Other specific services may also be offered, depending on the 

rights assigned to your extension, or your facility’s configuration.
More specifically, your extension may also provide you with the 

means to control your external ISDN call costs. 

Locking Your Extension

When you are absent, you can lock your extension, restricting its 

use by any third party.
When your extension is locked, it is impossible to access the 

external network. Only the external emergency numbers may be 

dialled – typically 15, 17, 18, and 112.
It remains impossible, however, to place internal calls and/or 

receive any type of call whatsoever.
Your personal data – your extension’s programming data and call 

log file – cannot be accessed. Access to the services usually offered 

by your extension may also be restricted.
