6.2 Functions of the Line Button
The Line buttons represent the available lines. You can assign a number to every line to be used for incoming and outgoing calls. Furthermore, you can define a time period for each line in which this line is blocked for further incoming calls (
6.1.7 Disabling Lines (Wrap-up Time)).
Example:
If you assign the number “100” to line 1, the number “100” will be transmitted when outgoing calls are made on this line, i.e. the person being called will see the number “100” on his telephone display. If you are being called on “100”, then you will receive the call on Line 1.
