Rang twice and they hung up.  Googled it to see who it was.  Blocked it in my Blocked Call List.  Aggregating!

I used my desk phone at work to call the number back after it rang twice and they hung up. It just said in a Robo voice..THIS IS LISA CALLING FROM THE REWARDS REDEMPTION.  WE ARE CALLING YOU  BECAUSE YOU HAVE WON A GIFT REWARD OF 100 FROM ONE OF OUR RETAIL STORES LIKE WALMART (and it named a couple others I already forgot the names of).  STAY ON THE LINE TO BE CONNECTED TO SOMEONE WHO CAN TAKE YOUR INFORMATION TO SEND YOU YOUR 100 REBATE CARD. I hung up as I'm sure it was a scam of some kind or other.

Got a call, No message left. I am on a do not call list.

Don't call them back unless you *67 before dialing.  When you call back, they know they have a live phone number.  Probably selling your phone # to other spammers.

Unless things have changed, *67 is not guaranteed to block your number to all numbers that you dial. It depends on how their system is set up.
