I got this call while I was at work. I discarded it since I did not recognize the number and it had no caller ID. Then I looked it up and found that this is a presumptive advertising call for someone working a scam. I have a National Do Not Call number. Obviously, it means nothing since these lame brains do not check to see if they can legitimately call someone they do not even know.
I received a call 5 minutes ago and just let it ring, 5 or 6 rings, before the caller disconnected. Caller didn't leave a voicemail. Blocked and forwarded number to FTC.
