Busy Lamp Field
Check your colleagues’ availability and answer calls at the click of a button
What is a Busy Lamp Field?
Busy lamp field, or BLF, is a light on your IP phone which will tell you whether or not an extension number on your phone system is busy or available to take a call.
By using BLF you can visually see whether your colleague is on a call before transferring allowing you to better serve the caller. This feature also allows you to answer incoming calls to other extensions via one click of your BLF button, preventing missed calls while your colleague is away from their desk.
