I let the phone ring, and they did not leave voice mail. I called the number back. "All of our representatives are busy at the moment. Press 1 if you do not want to be on our "Do not call list." It may be insurance sales.
Called twice, I did not answer since I didn't recognize the number. They just hung up, did not leave a message. Very annoying. The only protection we have from these bogus phone calls is to not answer if we don't recognize the name or number. Thought the "Do Not Call" List was going to solve this problem, but it appears the scammers have found a way around it.
