Who called from 2088850623

I received this call twice.  No message

This should be a University of Idaho number, but searching for it on campus yields no information.

I have received calls from a "208-885" prefix for the last four or five weeks.  The last four numbers of each call have been similar; but different each time.  This number called last night.  They never leave a message.  I don't answer because I don't know the number.

I have received a call from 208-885-0623 several time over the past few months.  I have never answered it and they don't leave a message.  The prefix is from Moscow, ID
