Who called from 3072743625

Not an 800 number!!  Hope they're charged for calling you folks (we never pick up our home phone unless it's a familiar no.).  How much fun can it be for pranksters in Cheyenne (1400 miles away)??  They'd probably find Jimmy Kimmel more entertaining on a Wednesday night.

Received a phone call from this number at 10:42 P.M AZ time.  They hung up as soon as I answered.

They called at 12:54am! Left a message that sounds like water running. Called back, rang 2 times, got busy signal. Wth is this?

Got a call at 12:32 A.M.
They waited until answering machine came on and didn't leave a message.

I received a call from this number at 2:21AM and woke me up. I tried to call them back at 6:35 (3:35AM Wyoming) time and there was nothing; no ring, no busy signal, nothing. My number is already on the Do Not Call list. I hate these calls.
