I got a call from 440-519-6763 at 10:17 am on April 2, 2016.  The caller did not leave a message even though my answering machine was on.  My caller ID said, "Out of area," which almost always means a telemarketer.  I have been on the federal Do Not Call list for over ten years.  Don't legitimate companies use their real name for their ID?  I would think so.  Why hide your name if it is a legitimate business call?
