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 6735i, 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.
Configuring a BLF Key
Use the following procedure to set a key to function as "BLF". The procedure shows the softkey screens as an example.
Note:
The BLF setting is applicable to the Asterisk server only.
Note:
You can also use a BLF configured key to dial out. Contact your System Administrator for more information
