Could I be so lucky to be first again!!! No message, so blocked!

Caller seems to be targeting our area today (2-17-17) as I see another posted about it just an hour ago. There was only silence on the line.  Likely a scammer or prank.

CallerID says "unkown name". Left no message.  First time I've seen this number.

No message left. Fake number. Not a 310 number.

Called landline at 10:44am; left no msg.
