 I've worked in the telecommunications business for 7 years now. I noticed there wasn't any discussion on third party billing since the time of divestiture.  The latest incarnation of placing third party charges onto a bill has been the notion of allowing digital content purchased in an eCommerce fashion (real time authentications, authorizations, etc) to appear on the telephone bill.  In this article, there are references to the three providers of this core service and a brief history as to how this came about. 

 Comments are welcome.
