Here you can find the description how to use the BLF keys in a Broadsoft environment. (For security reasons we removed the URL's in the example below)

Broadsoft configuration

In Broadsoft management system go to: Users - Select the user - Client Applications - Busy Lamp Field

  • Define the URI for the BLF list, must be an unique name.
  • Add the Users you would like to have under the BLF keys to the Monitored Users list

Settings - Function Keys and add the BLF key.

For the Phone number you need to enter the same naming as in the broadsoft Monitored Users list








Subscribe is only send when BLF key is configured. When no BLF key is present then device will not send subscribe.
