These spammer scammers phoned before and at that time mentioned the Do Not Call list. That was a couple of months ago.
When they called today their call was blocked (thank you Panasonic cordless phone) and although the area code is the same as mine the caller ID showed "Out of Area".
The robodialer software can be set to automatically generate a caller ID which is a city close to the number it is calling in the hope that the target might think it is a legitimate call because it is local, and therefore answers the phone. I can always tell a robo call when the caller ID is a nearby city like Los Angeles or Malibu or Beverly Hills (real popular ones). No individual or business will have a city name as their caller ID.
Received calls from this number several times. I decided to answer, they asked if I was the homeowner and when I anwered yes, they hung up. I was concerned that I said yes and how they could use my voice response for some fraudulent purchase.
