I don't answer calls for numbers I don't recognize so listened to the message.  Male voice just said hello, then hung up.

One of many calls we get from totally spoofed numbers. I never answer unknown numbers. I just block them. As we get more and more calls from criminals using spoofed numbers it becomes apparent that more of us are aware of their tricks and forcing them to turn to more desperate measures. I pray that more and more honest hard working people continue to be alert to these criminals and all of their tactics and someday it will no longer be profitable for these no goods.
