If you have any other model of Yealink handset, please see our other articles.

What is BLF?

BLF stands for Busy Lamp Field and is a great feature, particularly for teams working remotely. Have you ever found yourself in a position where you need to make or transfer a call to a remote colleague but you don’t know if they’re already on the phone? This is where the Busy Lamp Field comes in…

The BLF keys on your phone will allow you quickly see the phone status of that person. Each BLF key shows the status for an individual extension/user on the phone system so if you’ve got 5 people in your team, you’ll need 5 BLF keys.

GREEN means the person is available to take the call and RED means they’re not. Simple.

The below procedure will take you through setting up BLF keys on the following handsets: T53, T53W, T54W, T56A and T57W.
