Automatic Call Distribution (ACD) is the basic building block for call center applications. ACD offers you a method for distributing incoming calls efficiently and equitably among available agents. With ACD, incoming calls can be directed to the first idle or most idle agent within a group of agents. ACD and Call Center Elite provide a very feature rich complement of routing and call handling capabilities. For more information about Automatic Call Distribution, see the Avaya Aura® Call Center Overview and Avaya Aura®Call Center Feature Reference guides.
