Busy lamp field indicators

Last Updated : Nov 21, 2014 |

Busy lamp field (BLF) indicators show when a button or associated feature is active.

Digital and IP phones have programmable buttons which can be assigned to various features. When those buttons include some form of BLF indicator, the button can also be used to indicate when the feature is active. For example, a button associated with another user will indicate when that user is active on a call. A button associated with a group will indicate when the group has calls waiting to be answered.

The directory entries in and the speed dial icons within the Phone Manager and SoftConsole applications also act as BLFs. When the icons are associated with internal users, the icons will change to indicate the current status of the users.

Avaya one-X® Portal for IP Office shows these conditions:
