What is BLF?

BLF stands for Busy Lamp Field. BLF is a feature in which unused line keys on your desk phone monitor the status of other phones on your account.

This feature is useful for the receptionist of a 10 person company who sees everyone's status, or it could be a personal assistant who monitors their boss' line.

The monitoring line blinks green if the target is receiving a call and goes solid red if they are currently talking on the phone.

See why 100,000 companies trust Nextiva for VoIP service.
