Dec 11, 2020

BLF Introduction

BLF, or Busy Lamp Field show the status of other users' phones(busy,ringing, available) connected to your phone system. Required is that you have this user on one of your BLFs and that your phone has BLF in the first place. Most IP phones use multi color LEDs to indicate the status of another phone. BLFs can also be used to call other users by pushing the BLF button.

BLF and Pickups

Some phone systems also allow to do pickups of the phones of other users. This way you can pickup calls from your users when they are not available. Usually users need to be members of the same pickup group, in order to pick up each others phones. Pickups can be combined with BLF. When the phone of another users is ringing, this is indicated by a blinking BLF on your phone. If you and the other user are in the same pickup group, you can pickup the phone by pressing the BLF button on your phone.
