Who called from 8013700000

JUST fell asleep and this number calls-no one there-no message-just silence-AT 9:20 PM!!!!!!!!!!!!!!!!!!!!

This number called an employee on 4/17 beginning at 3:45, called 4 times every 6 minutes and when they picked it up the phone rang. I tried to call the number and it said you have reached a number that has been disconnected. In a googld search it said the number came from Provo, Utah.

Same thing as others above

Same as above, has called in middle of night, middle of day, etc., always fax beep.

recieved call from the Provo UT #
just beeping--is it hackers-scammers?
Called local phone Co--no help
