AT&T/BellSouth/Cingular Mega-Merger Is All About IMS

he importance of the IP Multimedia Subsystem (IMS) architecture has never been more abundantly clear than when AT&T recently disclosed its mega-merger plans to combine forces with BellSouth and Cingular Wireless. Many analysts, in fact, think the prime motivator for the $67 billion deal was the promise of convergence (i.e., wireless bundling, integrated offerings, etc.) as opposed to the billions of dollars in potential savings that could be squeezed out in operating efficiencies.
