Voice over Internet Protocol (VoIP) is a new fancy and up growing technology. A major change in telecommunication industry is VoIP. The transmission of Real time voice data is not as easy as ordinary text data. The real time voice transmission faces lot of difficulties. It suffers from packet loss, delay, quality and security. These factors will affects and degrade the performance and quality of a VoIP. This paper addresses the security and packet delivery ratio of a VoIP using modified secret sharing algorithm over a single path with reduced packet loss. The simulation results show that higher security is achieved in terms of route request, route reply error, delay, and packet delivery ratio.
