Called once on my OFFICE phone, and twice on my cell phone today. Didn't recognize it, and glad now I didn't pick-up. On my cellphone, I just added the number to my "SCAM" contact to which I've assigned a barking dog ringtone. That is my cathartic relief hearing that ringtone, imagining a pit bull barking at an intruder - otherwise I would assign a ringtone of "silence".
For home phones, I recommend screening all calls through an answering machine. If it's important, they'll eventually leave a message. I've taken-on the additional process of recording the telephone company's 3-tone "disconnected" signal at the very beginning of my outgoing message. When the robot dialers encounter that, eventually the number is dropped from their "dial" list. Eventually...
But, because these phone spammers sell each other their phone lists, it will take many months before there is a noticeable reduction in the calls, but it does work.
