I receive regular calls from this Number everyday, however most of them are when I am not at home, and although my answering machine always gives the caller an opportunity to leave a message the caller always hangs up.  I do not take calls from unknown callers even businesses.  I go on the principle that if they want to speak with me they will leave a number and I will call back on my nickel.  The number this caller leaves on my caller ID never seems to work.
