In an Avaya Aura® environment, you can use the Bridged Line Appearance (BLA) call feature on Avaya Vantage™ Connect directly or through the Avaya Connect Expansion Module application. This section describes how to use BLA directly with Avaya Vantage™ Connect.

BLA is a unique primary extension number that multiple users can share among themselves. You can make, receive, and join a call on behalf of the owner of the primary extension by using the bridged line appearance.

A typical use case for BLA is a boss and secretary scenario. In this scenario, the primary number belongs to the boss. The administrator configures the call appearances of the primary number on the secretary’s extension. When someone calls the boss, either the boss or secretary can answer the call. If the secretary answers the call first, the boss can bridge onto the call. If a call comes to the extension of the secretary, the boss cannot see this call or bridge onto it.

On Avaya Vantage™ Connect, you cannot make a call on behalf of the boss using the BLA extension. You must connect an Avaya Connect Expansion Module application with Avaya Vantage™ Connect to make a call using the BLA extension.
