This manual is designed to guide customers through setting up the BLF (Busy Light Function) feature on compatible Yealink phones. The guide will presume you have already configured the VoIP registration settings. If you still need to register the phone to upstream, please check the Setup Guides page or call upstream on 1300 366 165.
BLF keys on the phone can be configured in two ways, either using the web interface or directly on the handset. Each of these are broken out into their relevant section below.
