Introduction:
BLF is an acronym for Busy Lamp Field, which is a light on an IP Phone or a colored indicator next to a name in a Softphone or Web client, that tells you whether another extension connected to the same PBX is busy or not.This feature allows a Monitor Account/Extension to see the status of other extensions. By activating this function, the user will be able to:
- Check if another extension is currently on a call;
- See if there’s an incoming call to other extensions, and;
- If unanswered, User will be able to pick up the call of another extension.
