What is a predictive dialer?

A predictive dialer is an outbound auto dialer software that dials numbers ahead of time and only connects answered calls to free agents. It skips bad, unanswered, busy numbers and even answering machines. This helps increase the efficiency of agents in a call center campaign exponentially.

How does predictive dialer software work?

The predictive dialer connects a call to an agent as soon as they are free by dialing numbers ahead of time. The algorithm works by calculating the dialing ratio based on stats like answered calls, dropped calls, and number of active agents and predicting the appropriate dial rate for the next round.
