Who called from 9251647558

Called and when I picked up the phone the caller started making beat-box sounds and then hung up after 3 seconds or so.

left no message

This is the second time I got a call from this number.  No one is on the line, then I get an electonic voice that says "Good Bye" at about the 3 second mark.  Very annoying since the calls come in after 11pm. Hope they catch these creeps.

They called us tonight as well.  Same thing happened to us after midnight.

Called twice today - no one on the line when I answer; didn't wait long enough for recorded "Goodbye."
