The audio session is established on your phone.
Busy Lamp Field
With the Busy Lamp Field (BLF) feature, you can monitor the call status of other phones
connected to the same network.
Important:
BLF lines are not call appearance lines and cannot be used to make calls.
In the Broadsoft environment, you can add a BLF user from the Phone screen.
In the Asterisk environment, the system administrator adds the new BLF user.
Depending on the configuration, you can use BLF lines to the following tasks:
• Monitor the activity status of the phone.
• Receive incoming calls for another user that is Directed Call Pickup.
• Speed Dial of a BLF user in an idle state.
• View outgoing call status.
• Barge-in on an active call.
• Unpark a call in the Broadsoft environment.
The administrator configures the action of the BLF line key. Depending on the configuration, when
you press the BLF line key, the phone does one of the following:
First soft key is the key on the bottom left corner of the phone screen.
• Performs the action of left-most soft key on the phone screen.
• Highlights the corresponding line.
• Does not take any action if the corresponding line is already highlighted.
However, in this case you can use the OK button on the phone to perform the action of the
first soft key.
