We started Ozonetel in 2007 with a vision to build voice services . We have always been involved in voice services and even had a hosted VXML platform which we used to power voice services for the automobile industry. We also developed self service IVR applications for Telecom companies on Avaya. During this time, we were building our own platform. Our experience with different vendors led us to believe that the only way to approach this problem was to own the whole stack. So while we were doing services, we started designing our own PRI card, the hardware which receives the calls. Finally, in 2010, we had a good and stable hardware design. Building hardware is real hard work. There is very little scope for mistakes. In software, you make a mistake, some one raises a ticket, you checkout the source code, patch the code and check it back in and everything is fine. In hardware, you make a mistake, the whole batch of fabricated hardware is gone. There is no way to recover it....
