Middleware 2007 Works in Progress

We propose a Web-service-based P2P architecture for VoIP called service-oriented VoIP. SOVoIP provides interoperability between protocols from both telephony and data networks using the converging behavior of Web services while ensuring security, extendability, and mobility. We also address other critical issues related to VoIP such as network address translation and firewall traversal, Enhanced 911, and the Communication Assistance for Law Enforcement Act. SOVoIP also provides modularity and reusability, making client development easier. Extendability in the Web service architecture is transparent to the client, so frequent client updates aren´t required in order to consume new features. This reduces the time and money spent on upgrades.
