A predictive dialer is an outbound dialing system that selects numbers from a list and dials them automatically. A predictive dialer dials numbers before detecting a link, at which point the call is transferred to a live agent. Dialers filter out busy signals, voicemails, no-answers, disconnected numbers, and so on. A predictive dialer helps sales agents do their job in the most effective, efficient, and productive way possible. They use an algorithm to dial numbers and connect with people.
