Line Keys and Programmable Keys

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.

Note: The BLF setting is applicable to the Asterisk server only.

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 6731i, 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.

Note: You can also use a BLF configured key to dial out. Contact your System

Administrator for more information
