I get a call from this number at least once a day.  It's been happening for weeks.  Let it go to voicemail, as it appears to be some kind of telemarketer.  The guy talks to the answering machine like it is a real person, "hello, hello, is Matthew there??" and then hangs up.  Reported to donotcall.gov.  This is getting to be a real nuisance.  Thinking of buying a fax machine to connect to the landline permanently.  That might fix the problem??
