Also, before I talked to the messages I would pick up the phone and remain silent, that too ended the call, I knew it was a scammer from the caller display. After doing that for a while I would answer the call with a grunt, then the recorded message would kick in, one of many, so that's when I had the thought that somebody was waiting for an answer so they could press a button to start the recorded message. When I started "talking" to them and the call would come to an abrupt end mid message, sometimes with the click of a receiver I knew I wasn't being mad talking back to them.
