Blocking numbers CAN help. I regularly block numbers on my land line. My landline frequently displays the message "Blocked call" in the caller ID section. One of the numbers that I had already blocked tried again. If it was blocked because of the call screening, it just displays "Missed call."

This. I also pay Verizon monthly for use of their Call Filter app. Not the most effective out there vs T Mobile's or AT&T from what I've read, but it's definitely made a difference in the volume of garbage calls I receive.
