Abstract :
This paper outlines the call routing in the current H.323-based VOIP network, analyzes the drawbacks of the theoretical architecture of softswitch , and presents three call routing models of softswitch in the migration form existing public switched telephone network (NGN). One of its key aspects is the introduction to the concept of TRIP, which can be the standard routing protocol in the future NGN.
