This call says it's from the jail and to press 1 to help the person calling you.  Since I've already put up with the Grandma call and the Microsoft needs to connect to your computer call, I just hung up.  The number says it's from Ogden Utah, but the number does not match any numbers for correctional institutions in Utah.  I am on the Do Not Call List - how do we stop these?

They have called me a total of 8 times within the hour. When I pick up it says its a prepaid call and hangs up!
I'm on the DNC, knock this Bull [***] off.

It called me 2 times (so far today). I didn't respond. I hung up.
I called the number back and a message said "this phone is not available."
