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.
Example
A Supervisor configures BLFs on his phone for monitoring the status of a worker's phone use
(busy or idle). When the worker picks up his phone to make a call, a busy indicator on the
Supervisor's phone shows that the worker's phone is in use and busy.
On the 9480i, the busy and idle indicators show on the IP phone screen display next to the key
programmed for BLF functionality. When the monitored user is idle, an icon with the handset
on-hook shows next to the BLF key. When the monitored user is on an active call, a small
telephone icon is shown with the handset off-hook.
