Received a phone call from this number today.
I did not answer the phone, and they did not leave a message on my answering machine.
My caller ID reads this phone number as "CLAREMONT UNIVS."

Some research via the internet has identified this number to be from a professor at Harvey Mudd College (in the greater Claremont Colleges campus area). I have no connections to this college, what-so-ever.
Not sure if the professor actually tried to call me, or if some scammers are using (spoofing) the number for their own mischievous purpose.
