CID Tucson, AZ. No message. I like "dumb's" idea. I think I'll buy a loud whistle and start answering some of these calls. As soon as you know it is scam or ripoff, blow the whistle as loud as you can! Blocked #.
This number called today, a Saturday. Left a voicemail which consisted of a short mechanical shriek, a long pause, a man saying "hello?" another long pause, the same "hello?" voice-clip, and then click.
