Phone rang, but soon as I answered it the other end hung up. I pulled up the number on display and pressed talk. It rang, then a recorded message came on telling me to press 2 to be added to their "do not call list." I pressed 2 and a recording asked for my 10 digit phone number. I did and the last recording said my number had been placed on their "do not call" list. I've no idea if this was a spam phone call to verify my phone so they can continue to send phone spam. My number is unlisted and I'm sure it was an autodial situation.
