No clue who they are, I won't answer it. Have seen posts from other people saying not to answer. Don't know how they got my number, but I am on the do not call list.
They called me today, too. But I doubt it was really Southern Methodist University. They woould have no reason in the world to call me. Next time, I'll answer and find out.
Received a call today, 27 Jan 15. I always refuse to answer unless a message is left, which it wasn't. I then checked and saw that it's a telemarketer. They ignore the do not call list!
