Getting one call a day after business hours.  Who is this is?

Calling daily, never leaves message. Anyone know this #?

Also calling daily after business hours and never leaves a message.

The number belongs to Edgewood College in Madison, WI.  I think they use this number for fundraising drives - I'm an alumnus of Edgewood College.  I've gotten six calls over the past week leading up to May 1, 2013, all between 5 PM and 8 PM.  They must be raising money right now.
