  • Predictive Dialer Software

    Predictive dialer software is designed to automatically dial the correct number of telephone calls to match the pattern of available call center personnel.

    Without predictive dialing software, an outbound call center will have to wait between phone calls until another person answers the phone. This can be quite expensive in terms of lost productivity. With a predictive dialer, a new phone call should be available as soon as the call center agent hangs up with the last phone call.

    Predictive dialer software accomplishes this by forecasting how many telephone calls need to be placed. If the predictive dialer software does not place enough calls, the agents will sit idle waiting for a call. If the predictive dialer software places too many calls, no agent will be available to speak with the person who answers the phone. If you have ever received a telephone call and heard a recorded message that said something like “Please hold the line for the next available agent”, you have experienced a predictive dialer failure.
