Busy Lamp Field overview
This feature indicates which phones on the system are in use by displaying a clear status on your phone display. Each BLF key on your phone also acts as a speed dial.
How Busy Lamp Field works
Busy Lamp Field supports up to 50 lines and allows you to display the phone status of other extensions on your phone, such as “idle,” “ringing,” or “on a call.” Each BLF key on your phone also acts as a speed dial, allowing you to press that key to dial the corresponding extension.
