The Busy Lamp Field (BLF) feature enhances support for a phone-based 

attendant console. It allows monitoring the hook status and remote party 

information of users through the busy lamp fields and displays on an 

attendant console phone.
In the SIP 3.1 release, the BLF feature is updated for the following:

• Visual indication when a remote line is in an alerting state

• Display of the caller ID of calls on remotely monitored lines

• Single button “Directed Call Pickup” on a remote line
For more information, refer to “Quick Tip 37381: Enhanced BLF“ at

.

Configuration changes can performed centrally at the boot server:

The phone’s user interface can be customized by changing the fonts and 

graphic icons used on the display and the LED indicator patterns. Pre-existing 

fonts embedded in the software can be overwritten or new fonts can be 

downloaded. The bitmaps and bitmap animations used for graphic icons on 

the display can be changed and repositioned. LED flashing sequences and 

colors can be changed.

Polycom recommends that the BLF not be used in conjunction with the Microsoft 
Live Communications Server 2005 feature. For more information, refer to

Use this feature with TCPpreferred transport (refer to

). You can also use UDP transport on SoundPoint IP 650 and 670 phones.
