How to Effectively Transition to VoIP and IMS - Big Bang or Phased Approach?

Cover
This white paper describes the key drivers motivating service providers to migrate to IPbased networks as well as the most effective first steps, including the network topologies involved in the transformation. A number of design and implementation issues can have a major impact on the transition as the service provider prepares its network as a platform on which to build IMS-based services and grow revenues. The problems associated with taking a "big bang" approach - a one-time full migration - are compared to a phased approach that includes implementing partial VoIP and hybrid solutions on the road to full IMS.
