Introduction

Starting from v15.5 SP1 the provisioning of BLFs for IP phones has been extended to configure Line keys as well as BLFs. From the management console, going through an extension’s properties →  BLF tab, one can set BLFs of various types which are then provisioned.

Line Keys

The Line key button is self-explanatory and allows to create a new call/line from the phone. It also blinks on inbound calls. There used to be two line key buttons enforced by the provisioning template for all supported phones. Now it is no longer mandatory, you can have none or as many as you wish. Note that when the 3CX Client is used in CTI mode (legacy CTI), BLFs set as Line keys are mandatory on position 1 and 2! If you are using the Web client they may be placed anywhere or omitted. Snom Note: It is advised to have at least 2 BLF keys set as Line keys to make attendant transfers easy for the device user.

BLF

The Busy Lamp Field (BLF) has three functions: when pressed it dials someone’s extension and can also be used to ease transfers, color and flashing status changes according to the supervised extension (idle, ringing or busy) thus providing call information, and when the extension is ringing you can pickup the call.

To be able to pick up someone’s call see Managing Call Pick-Up Permissions for more information.

Speed Dial

Speed dials are used to dial extension numbers only, no presence information will be displayed on the light indicator.

Custom Speed Dial

Custom Speed dials are used to dial any external number or dial code. When adding a Custom Speed Dial, the user must dial the number,  and a First Name and Last Name that will be used in the label is displayed on screens. No light indicator will be used.

Profile Status

Profile Status BLFs allows to change the extension’s status to the one specified: Available, Away, Do Not Disturb, Lunch, or Business Trip. No light indicator will be used.

Queue Status

The Queue Status BLF allows to change the extension’s global queue  Logged In status to the one specified, either Logged In or Logged Out. No light indicator will be used

Shared Parking

The Shared Parking BLF allows to park a call to the shared park slot specified, or to unpark a call from this slot. Light indicator is used to represent call parked.
