Setting a "Busy Lamp Field"
(BLF) Key
The BLF feature on the IP phones
allows a specific extension to be
monitored for state changes. BLF
monitors the status (busy or idle)
of extensions on the IP phone.
Note: The BLF setting is applicable to
the Asterisk server only.
Example
A Supervisor configures BLFs on
his phone for monitoring the status
of a worker’s phone use (busy or
idle). When the worker picks up
his phone to make a call, a busy
indicator on the Supervisor’s
phone shows that the worker’s
phone is in use and busy.
On the 9133i, the busy and idle
indicators are the LEDs next to
each BLF programmable key. The
LED illuminates steady to indicate
the monitored line is off-hook or
unregistered. The LED goes off
when the line is idle.
You can set BLF on the
programmable keys using the
Aastra Web UI only. BLF is not
configurable from the IP phone UI.
Note: You can also use a BLF config-
ured key to dial out.

Setting a "BLF List Key"
(For use with the BroadSoft
Broadworks Rel 13 or higher
platform only)
The BLF\List feature on the IP
phones is specifically designed to
support the BroadSoft Broadworks
Rel 13 Busy Lamp Field feature.
This feature allows the IP phone to
subscribe to a list of monitored
users defined through the
BroadWorks web portal.
Note: Your system administrator must
have BLF List enabled on the
BroadWorks Server. Contact
your system administrator for
more information.
In addition to monitoring the idle
and busy state, the BLF\List feature
also supports the ringing state. On
the 9133i phone, the LED lights
next to each BLF programmable
key illuminate steady to indicate
the monitored line is off-hook or
unregistered. The LED goes off
when the is idle. When the
monitored extension is ringing, the
LED flashes.
The Broadworks BLF feature is not
the same as the Broadworks
Shared Call Appearance (SCA)
feature and does not permit call
control over the monitored
extension.
