Busy Lamp Field (BLF) Key
The BLF feature on the IP phones allows a specific extension to be monitored for state changes. BLF monitors the status
(busy or idle) of extensions on the IP phone.
For example, a Supervisor configures BLFs on his phone for monitoring the status of a co-worker’s phone use (busy or idle).
If the co-worker’s phone is in an idle state, the
BLF
key’s LED on the Supervisor’s phone is off. If the co-worker is on a call or
when the co-worker picks up his phone to make a call, the
BLF
key’s LED on the Supervisor’s phone turns on and is solid,
indicating that the worker’s phone is in use and busy.
