We all get pesky robocalls and each one presents a problem. If we do not recognize the number, should we answer? Ignore? Block the number?
Apparently, the answer is that none of these actions make much of a difference.
To better understand how these unwanted callers operate, we monitored every phone call received to over 66,000 phone lines in our telephone security lab, the Robocall Observatory at North Carolina State University. We received 1.48 million unsolicited phone calls over the course of the study. Some of these calls we answered, while others we let ring. Contrary to popular wisdom, we found that answering calls makes no difference in the number of robocalls received by a phone number. The weekly volume of robocalls remained constant throughout the study.
