Next Generation Unified VoIP Telephony Developer

The VoIP Telephony is entering a new phase of evolution. The spread of participatory information-sharing over the world, combined with recent improvements in lower cost internet access in developing countries, has opened up new possibilities for Next Generation VoIP Telephony Applications and Unified Communications. However, most people in the VoIP industry would agree that VoIP now focuses on several major themes, including multimedia, video, fax, presence, collaboration and media sharing. While the innovations and practices of VoIP will continue to develop, they are not the final step in the evolution of the VoIP. In fact, there is a lot more in store for the VoIP. We are starting to witness the convergence of several growing technology trends. These trends have been gestating for a decade and will soon reach a tipping point. At this juncture the next generation of the VoIP will start. So now VoIP apps should be developed and deployed as prepared for up-coming technology.
