Called at 12:17pm. Diverted by a service I subscribe to that intercepts robo-dialed calls (rhymes with SoNoHobo). I called back, using *67, and got a recorded message "All of our agents are busy. You will be called back shortly. Press 2 to be placed on our Do Not Call list."

Since I didn't make my number known (using *67), I didn't bother, nor would I, since they are obviously trying to get to me while hiding themselves.
