Premium Call Features
Busy Lamp Field (BLF)
(SIP/SP only.) BLF is a common collaborative feature for a user to monitor the extensions of other users from their
phone. BLF is a feature of the monitoring phone, The monitored extension usually does not do anything special to be
monitored. The detection and notification of events occurring at the monitored extensions are carried out by the soft-
switch.
When BLF is supported by a specific SP service on the OBi1000, the BLF function can be assigned to a feature key bound
to that service to monitor an extension in the context of that SP service (That is another extension on the same hosted
voice service or PABX system). We refer to a feature key that is assigned the BLF function as a BLF key. One BLF Key
monitors one extension only. The administrator can assign as many BLF Keys as there are feature keys available, to
monitor as many extensions. The following table lists the typical events that are monitored with a BLF Key. The table
also shows the operation that can be invoked when the respective event occurs, and the LED pattern indicating that
particular event.

Single Versus Multiple BLF Event Notification
There may be multiple events happening on the monitored extension for multiple concurrent calls (in various states).
For example, the monitored extension may be on a connected call while an incoming call is ringing. Under these
circumstances, some soft-switch implementations may only notify the monitoring phones of just one event that it
