Paper Abstract

With rapid development of computer network and a wide application of Internet, IP telephony has been realized. Currently, one of the most important research areas of IP telephony system is to develop the IP telephony gateway. In this paper, a new idea of design on an Integrated IP Telephony Gateway is proposed, and the hardware of Integrated IP Telephony is discussed in detail. The software architecture of the Integrated IP telephone gateway is studied, and this paper focus on the voice compression module and SPOX schedule module. In addition, Stochastic Petri Net Model of an Integrated IP Telephony Gateway is set up, and its performance analyzed through the Stochastic Petri Net model. Array of Petri Net Model is computed, and educes the mathematical relationship of CPU efficiency and structure parameters of the IP telephony gateway.
