"Hello, this is Sandra from the National Student Aid Center offering you a chance to save 40% on your student loan payments." Gee thanks, since I've never had a student loan. Robocall, obviously a scam.
I was apparently in a part of the house where I couldn't hear the phone ring, but this number called around lunch time today. No message was left. Caller ID says "Out of Area". A lot of good Caller ID is...most of the numbers that call like this can't be ID'd.
