Voice over Internet Protocol (VoIP) is one of the most prominent communications technologies today. The introduction of VoIP has resulted in a number of VoIP specific protocols those are not interoperable. Thus the next logical step is to make these and other existing protocols on the Internet talk to each other to bring about true convergence between voice and data. Naturally middleware that connects different software, platforms and protocols comes into the picture. In this paper we introduce a middleware based VoIP architecture, Service Oriented VoIP (SOVoIP), which ensures protocol convergence while addressing many critical issues related to VoIP such as: NAT and firewall traversal. We compare our solution with widely used existing VoIP solutions.
