The main difference is that a predictive dialer is a mass-call automation tool which dials several numbers at the same time, assigning a call to an available agent once it’s answered. The Power Dialer, however, dials numbers one after the other, ensuring the previous call is completed before dialing the next number. While the predictive dialer is used at the team level, the Power Dialer is a call automation tool managed at the individual agent level. A predictive dialer is properly designed to be used in large teams and is managed at the supervisor level. It enables the supervisor to optimize call productivity for the entire team. The Power Dialer is more adapted to small and medium teams.
