A specialized phone system for handling many incoming calls. Typically used by airlines, rent-a-car companies, hotels, etc., an ACD has four functions. First, it will recognize and answer an incoming call. Second, it will look in its database for instructions on what to do with that call. Third, based on that database’s instructions, it will send the call to a recording that “somebody will be with you soon, please don’t hang up.” Fourth, it will send the call to one operator of a group of operators as soon as that operator has completed their previous call and/or the caller has heard the canned message.
