Busy Lamp Field (BLF)

A BLF is a special module that is connected to a SIP phone to view the availability status of other employees. The BLF displays a list of employees and their availability status.

There are also SIP phone models that come with a built-in BLF.

The cloud PBX works with all popular vendors that produce consoles, such as Yealink, Grandstream, Cisco, Escene, and others.
