Development of NGN test-BED

Abstract

We have developed a test-bed for providing IP voice/video calling with voicemail facility in MCS. This setup is completely based on open standard solution to replace Cisco unified system which requires licensing cost for each service implementation and maintenance. Asterisk, which is an open source Private Branch Exchange (PBX) is a complete telecommunications platform and represents a highly valuable piece of software for providing network solutions using an open source environment by eliminating the cost of required licensing. This project is an initiative to provide a Next Generation Network (NGN) where one can test the desired modifications like PSTN connectivity, instant messaging, playback services etc.
