Automatic Call Distribution (ACD) is the feature that routes interactions based on an algorithm that determines the best available agent for the interaction. ACD is a system that distributes incoming calls (or other types of interactions) to agents or queues based on various criteria, such as agent skills, availability, priority, etc. ACD uses an algorithm that evaluates these criteria and assigns each interaction to the most appropriate agent or queue.References: https://help.mypurecloud.com/glossary/automatic-call-distribution-acd/ https://help.mypurecloud.com/articles/about-acd/
