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 9143i, the busy and idle indicators are the LEDs next to each BLF key. The LED illuminates steady to indicate the
monitored line is off-hook or unregistered. The LED goes off when the line is idle.
You can set BLF on the programmable keys using the Aastra Web UI only. BLF is not configurable from the IP phone UI.
Configuring a BLF Key
Note:
BLF feature availability is dependant on your call manager. Contact your System Administrator for more information.
