It's a home security sales call stating that you are eligible for the program. It does give you the option to push 8 to be placed on the Do Not Call list.
Did not pick up but when something like this gives you the option to be placed on a do not call list by pressing a button--don't do it. For all we know pressing 8 may actually give them access to our phone, and at the very least it gives them knowledge that someone is actively using that number and so they can sell the number to someone else
