BLF\List Setting
(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.
In addition to monitoring the idle and busy state, the BLF\List feature also supports the ringing
state. When the monitored user is idle, there is a small telephone icon shown with the handset
on-hook. When the monitored user is in ringing state, there is a small bell icon shown. When the
monitored user is on an active call then a small telephone icon is shown with the handset off-hook.
On 3-Line LCD phones, 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.
You can configure a BLF/List key on the IP Phones using the configuration files or the Aastra Web
UI. You can also specify a BLF list URI that the phone uses to access the required BLF list. You
can specify a BLF List URI using the “list uri” parameter in the configuration files or the BLF List
URI field in the Aastra Web UI at the path Operation->Softkeys/Programmable Keys/Expansion
Module Keys->Services->BLF List URI
. For more information about the “list uri” parameter, see
Appendix A, the section,

Example
A receptionist has a 6757i running Broadsoft firmware that subscribes to a list of extensions from
the BroadWorks Application Server. Each monitored extension in the list shows up individually
on the 6757i screen next to a softkey button. The softkey icons on the screen change depending on
the state of the extensions.
On 3-Line LCD phones running Broadsoft firmware, the programmable key LEDs illuminate
either flashing, solid, or turn off depending on the state of those extensions.
Note:
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.
Note:
On the 6739i, you can configure a BLF/List softkey using the IP
Phone UI also. For more information, see the Aastra Model 6739i IP
Phone User Guide.
