I'm receiving repeated calls from this number.  If you call it back the number either rings busy or you get through, hear a few tones and they you're disconnected.  My unlisted number is on the Do Not Call list.  I'm sick of being harrassed by these people.  I reported them to the FCC and recommend that everyone else do the same:  http://esupport.fcc.gov/complaints.htm

Received same call... it came up as Massachusetts and then the number. No one answered and when I tried calling back, the line was busy.
