I received a call at 2.15 am from this number, when I answered they asked for "Mike"; I asked who was calling, but there was no response. I hung up and called the number 12+ hours later, to find out who had been on the other end of the line; the call went to vm but I did not leave a message. A few minutes later a call came in from this number; I answered but there was no sound from the other end, until someone began pushing buttons and blaring noise in my ear.
