Who called from 3052849990

UM Bookstore calling to tell my husband a textbook he was waiting for came in.

Keep getting these on my cell phone every day. No message.  I called it back and it said it was a non-working number at UM.

This appears to be a main outgoing line that appears on caller ID, from University of Miami. It could be any department from UM, which in my case ended up being for my daughter's music class.
