Call comes through several times per week.  I have answered but there is no immediate response, so I hang up.  I just called the number and got a recording.  The recording said they were contacting on behalf of one of their political or non-profit clients.  That explains lots of people getting calls from the number.

They called on 3/26/2008 at 5:20.
I answered but nobody was there.

Called about 4PM

I have also received several calls from this number which lists on the ID as a Peabody,MA number.  I believe this is a fax machine in that area.  The messages left on my machine are fax signals.

yup, it was political drivel.  That's one more canidate down I'm not voting for.  Phone spammers.
