With the fast development of IP telephony, there is a need to quickly provide more powerful and competitive multimedia services in the IP network. A natural choice is to integrate the intelligent network and IP network and exploit the mature capabilities of service creation and service deployment of the intelligent network in the IP network. This paper addresses a new call model between the intelligent network and the IP network for supporting the advanced multimedia service in the IP network using H.323. Firstly, the reason why the existing IN basic call state model is not suitable to model H.323 signaling are analyzed, then an enhanced call model based layered structure in order to fully exploit the advantages introduced by H.323 is proposed. Finally, we present an approach of the IP-SSP architecture based on the proposed model to fulfill the integration between the IN and IP
