We keep getting calls from this number and a number one digit lower. 508-409-6485.  I answer, the caller delays picking up and when they do it sounds like a lot of other people in the background (telemarketing warehouse.  They ask for my husband, when I tell them he's not home they say they'll call back later. I don't even get a chance to tell them to take us off their calling list.  I called back the number, a robot answering machine came on the line.  No company name given, just instructed to press 6 to be place on a do not call list.  Crossing my fingers and hope it works.
