CINEMA: Columbia InterNet Extensible Multimedia Architecture

Singh, Kundan; Jiang, Wenyu; Narayanan, Sankaran; Schulzrinne, Henning G.; Lennox, Jonathan

We describe the architecture and implementation of our Internet telephony system (CINEMA: Columbia InterNet Extensible Multimedia Architecture) intended to replace the departmental PBX (telephone switch). It interworks with the traditional telephone networks via a PSTN/IP gateway. It also serves as a corporate or campus infrastructure for existing and future services like web, email, video and streaming media. Initially intended for a few users, it will eventually replace the plain old telephones from our offices, due to the cost benefit and new services it offers. We also discuss common inter-operability problems between the PBX and the gateway. This paper is intended as a design document of the overall system.
