This number keeps dialing me and doing the classic prank phone call hang up without saying anything over the line.  The phone calls persist repeatedly even after getting ignored 6 or 7 times.  When I try to return the call I get sent to voicemail.  When I try to return the call from another phone, this number then started prank dialing the other number.

I too have been receiving prank calls and text messages from this number. They will call multiple times between midnight and 9 AM PT. If I answer, I only hear silence on the other end.
