It is Big Brothers Big Sisters auto dialer to find valid phone #s within their pick up area and to determine when you are home so a rep can contact you. It is legit but annoying. Also if you call back (I did) it rings once then goes silent then logs you # (I think that is what it did it sounded like my # on touch tone). This also lets them know it is a valid # and that you are home. You can call 413-785-5306 or the Hartsprings center at 413.732.7111 (toll-free 1.888.413.2227). Depending on your phone service provider you may be able to block the call if they are annoying or offending you that much.
