Visual Indicators
The phone system can notify the end user the hook status of the monitored extension by changing the icon
color and status.
For example, the screenshot below shows the BLF indicators’ status when the extension 1014 places a
call to the extension 1025. While the extension 1025 is ringing, the caller 1014’s indicator is blinking green
and the callee 1025’s indicator is blinking red. On the account widget, the indicators’ status is same as the
ones on the Programmable Key widget.
Figure 6: BLF Indicators Status
The following table shows the BLF indicator status in different scenarios, it requires the monitored

Directed Call Pickup
Directed call pickup feature allows the GXV34XX phone system to be able to answer the calls to the
monitored users. This feature is very useful for the attendant to help the specified callees to answer the call
if the callees are not available to answer it.
For the BroadWorks system, it requires to dial the specified prefix ahead of the monitored extension to
directed pick up the call. Thus, the end user must configure the prefix to GXV34XX to implement this
feature.
The following screenshot shows the *97 is configured as the prefix under the Programmable Key General
Settings page:
Figure 7: Configure BLF Call Pickup Prefix
Then, when the monitored user’s indicator is blinking red, namely there is an incoming call, the GXV34XX
phone user should tap the “Busy Lamp Field” icon to answer the call for the monitored user.
