Looks like a call from North East, Maryland. Most likely spoofers.  No one other end.  When you call back you get a recording that says "your call is very important to us" an to press 1 "for a representative."  I don't know what they are representing but it can't be good.  They put you on hold and force you listen to hideous muzak.   After exactly 2 minutes the line goes dead.    Spammers, Scammers and/or Spoofers.
