service is active. To do so, repeat the procedure, selecting 
a different type of background music.
You can control the volume level for the background music.

Hot Line Call to Attendants
According to a specific right assigned to your extension, you may 
also be allowed to take advantage of the hot line call to attendants 
service.
In this case, whether in handset or handsfree mode, a call to your 
facility’s attendants will be placed when your phone has been off 
the hook for a typical delay of 0.8 seconds, without any action 
required on your part.
You still have the option of calling any internal or external party by 
dialling a number (or any other equivalent action) before this time-
frame expires.
