Balancing innovation and preservation in telephony

Telephony might become just another application on the Internet. To examine if this is a likely or even desireable future, is the topic of this article. Everyone used to know what telephony is but with the appearance of software applications like Skype it isn't that easy anymore. Telephony in the traditional sense is interactive voice conversation between two people connected to a global network. When we talk about connectivity to a global network today, we envisage the Internet and when we talk about telephony, it is mobile telephony. The technological platform for telecommunications seems to evolve towards a common data network for all applications. The service specific silo-like networks convert towards a layered network architecture. When the underlying technology changes it remains critical to entangle the telephony application from technology. This article tries to find a clear seperation between application and technology and explores innovations of the telephony application in the light of convergence of computers, media and telecommunications. Innovations should be balanced against society's needs to preserve a world wide network for voice communications.
