no voice when the call goes through, when I call it back it says the number has been disconnected

think it is University of Delaware soliciting for donations.  did you go there?  I remember them owning all of 302-831-xxxx when I was a student

Received a call from this number on 1/5/10.  I didn't pick up, they didn't leave a message, and when I called back it said that the number has been disconnected.  The exchange makes me think this is a University of Delaware number.  831 numbers are usually office numbers there.
