Many people wonder if turning off answering machine detection will hurt their productivity numbers. After all, isn't screening out answering machines the reason why we use dialers?
The speed advantage that comes with using a predictive dialer doesn't come from excluding answering machines. Using a dialer, your phoners do not have to dial numbers, listen to ringing and wait for calls to be answered, hang up on unanswered calls, busy signals, and recorded messages about disconnected numbers. With a dialer they handle only the answered calls, and that is true even when you turn off answering machine detection.
Yes, they will handle significantly more calls when you turn off answering machine detection. Those calls will be very short - a second or two to hear that it was a machine, a click on the "Answering Machine" button on the screen, and back into the queue to handle another call. The dialer will make up for the time spent on those calls, because the dialer is able to go significantly faster - shorter wait times between calls - when there are a lot of very short calls.
We have analyzed the productivity results of campaigns that tried phoning with answering machine detection both off and on, and the productivity numbers were basically the same. Campaigns that turned off answering machine detection also reported that once they got used to it, their phoners actually preferred working with detection off, because the pace of the work was faster.
