Caller ID showed Unknown Name and they didn't leave a message.  Callback got a recording that said the party I was trying to reach was not available pleas leave a message.

same as Tom

Guy knew my first name. Said he was Steve, calling for Missouri State Troopers. I hung up and blocked the number. CID said Kansas City MO.

Annoyed~~~

So glad you posted.  I work in a senior's house I care for.  Two calls from that number (816-256-8249) yesterday....both times they were hangups.  I tried the number back a few times last night and it was busy each time.  Then sure enough, this morning we got a call from "Missouri State Troopers" wanting $20.00 from that number.
