Multiple calls per day from this number.  Haven't answered.  No message has been left.

Second day in a row this number has called and not left a message. Just says Missouri Call on caller I.D.

Repeated calls from this number; silence on the other end whether I answer or let the answering machine answer. Presumably this is a robocall machine identifying active numbers for future scam calls.

1 call from this number the day before yesterday, 3 calls yesterday, and 3 already today (and it's only 12:45pm)! Caller ID says "Out of area". I don't answer any calls when I don't recognize the number or the caller ID and no messages were left. If they're that desperate to reach me and they're legit, they'll leave a message. But I'm pretty sure (99.999%) these losers are spammers!
