this is a magicjack, magic number that they use to route calls from different devices. I know this because my family called me from it, from their tablet. This is a random number that magicjack uses to allow anybody to make calls for free. it is not a certain persons number, it is everybodys number who uses magicjack.
At 4:51a.m. on April 25 Friday, a weird voice called from this number saying I'm going to get u p, in this sinister joker kind of voice. This is really weird and creepy.
