In this day and age Voice over Internet Protocol (VoIP) has turned out to be a revolutionary technology in the field of telecommunication. Because of the escalating number of users of VoIP, it is essential to intend for a reliable VoIP system providing good quality of service. In this paper a stochastic model based on continuous time Markov chain is developed to analyze the reliability of a server based VoIP system comprising of significant components only. The concurrent breakdown of more than one component is taken into modeling concern. Redundancy at the component level is used with the purpose to boost the system reliability of VoIP. As a defensive course of action, software rejuvenation is implemented to avert or suspend software failures. And an optimal software rejuvenation strategy is proposed which leads to increased system reliability. Numerical results are presented for the quantitative examination of the suggested model.
