If you notice, ALL calls from this number have been on SUNDAYS.  Likely someone who is MOONLIGHTING as a scammer!

Caller ID said A.F.P.O.  Didn't answer.  Sunday, 1148.  I could imagine that families with military members overseas could jump at the call, thinking it a Christmas call from an APO or FPO area.  Absolutely despicable.

This old coot doesn't want to answer their calls, either.  Just got a call from this number, but no one on the line.

Caller ID shows
V21415291500049
607-203-5573
Whenever there is no name, (or my name and number spoofed as the caller) I normally just don't answer.
Received this call Sunday 15:29 EST, and I decided to answer.
There was a click, then an electronic sounding voice said, "hello, this is Joe, how are you today?"
That's when I hung up.

I received 3 calls today,  1 that came up as A.F.P.O.   607-203-5573 and 2 from the # 518-649-9923 all on sunday 12/14/14  4:18 pm & 4:25 pm ET.
