Voice over Internet Protocol (VoIP) is the reality of future telephony provided over the Internet. In the process it is claimed that, voice and data networks are converging into one network. However, such claim only introduced new protocols for telephony on the Internet which are not truly interoperable with existing protocols. Thus the authors propose a service oriented VoIP architecture, Service Oriented VoIP (SOVoIP), which not only ensures inclusive convergence of Internet and telephony but also ensures Quality of Service (QoS), Enhanced 911 (E911), Communication Assistance for Law Enforcement Act (CALEA), NAT and firewall traversal issue.
