JaiNir has developed very low coast software based IVRS solution based on Microsoft TAPI concept. TAPI provides access to a variety of telephone network services. Although these services may use different technologies to establish calls and transmit voice and data, TAPI makes these service-specific details transparent to applications. This means you can create applications that can take advantage of any available service without including service-specific code in your application. We have delivered this solution to Indian Railways..
