Phone rang first at 6:27a, waking both of us, but scaring me out of my wits as I dread the middle of the night phone calls expecting the worst as I have an elderly/ill mother.  I answered without checking the caller ID (wouldn't have been able to see it anyway without glasses), but no reply.  Same number called again at 6:29, again no reply.  Repeat at 6:31.  Crappy way to start the day.
