This number is operated by Affinity Global Collections (AffGlo is their new current name they're going by) and is used as a "calling beacon" to determine if the number called is picked up by a Human or not.  Shortly after receiving and answering a call from this number and following the prompt to press 1 to speak to an operator, I was forcibly disconnected after briefly hearing Human voices in a call center on the other end.  Less than 15 minutes later, Affglo called looking for what I can only surmise is the previous owner of my cell number -- a battle I have been fighting for over a year since getting this new phone and manually choosing this number.

The man calling was actually very nice and easy to talk to, leaving me alone without any lip or attitude as has been the typical behavior of debt collectors.
