Introduction: Appearance Buttons/Menu
1.11.6 Line Appearance Buttons
Line appearance buttons allow you to make and receive calls on a specific telephone line connected to your telephone
system. The button also allows you to see when the line is in use by other users.
For incoming calls, the telephone system still determines the destination for the call. That may be a user or group.
However, if you have a line appearance button for the line, you will see that there is a call alerting and can answer it if
required.
· Private Lines
Special behaviour is applied to calls where the user has both a line appearance for the line involved and is also the
Incoming Call Route destination of that call. Such calls will alert only on the Line Appearance button and not on any
other buttons. These calls will also not follow any forwarding.
Line Appearance Button Lamps
The following lamp states are used by appearance buttons configured to be line appearance buttons.
Alerting
The line is ringing at it incoming call route destination. This is accompanied by ringing. If the
user is already on a call, only a single ring is given.
