What is BLF (Busy Lamp Field)?

Set up Busy Lamp Field (BLF) in sipgate – display colleagues’ phone status on your own device.

If you want to display the telephone status of colleagues on your own phone, the busy lamp field (BLF) is the feature of your choice. It is included in the business L and XL plans. To use the function, the users you have created must have an internal extension assigned. Once correctly configured on the device, the BLF shows these three statuses:

  • available: colleagues are not on a call, the busy lamp is off.

  • busy: colleagues are speaking, the busy lamp stays on continuously.

  • ringing: colleagues are currently being called, the busy lamp flashes.

The BLF configurations differ from model to model.

Instructions for this can be found on the manufacturers' websites and in the documentation that came with your phone.

We have tested BLF configuration on a whole range of phone models; here you will find the configuration instructions for Snom, the configuration instructions for Gigaset, the configuration instructions for Yealink, the configuration instructions for Tiptel, the configuration instructions for Grandstream.

As an alternative to BLF, in your sipgate account you will find under My Telephony the presence display. This shows you which users are currently available.

If a user is on a call, the corresponding tile with the internal extension is shown in red.
