Who called from 6072544408

This caller never leaves a message. When I call back, I get a recorded messages that says "We're sorry, your call cannot be completed as dialed." Caller ID indicates that it's from Cornell University, but Cornell's directory doesn't include this number. Also, same drill with calls from 607-254-4438.

Alumni office, perhaps, looking for donations? They tried me, too, and I'm a Cornell alum. They didn't leave a message, though.

I am an alum too and I got the message. I would guess that it is the annual donation drive.

Same here.  I think it is for the annual fundraising.  It is getting pretty annoying.

It must be Cornell.  I'm also an alum.  Strangely, nobody answers when I say hello.
