IP telephony integrates modern computer networks (Internet/Intranet) with voice transmission and develops these, if needed, into Internet multimedia conferences. The Internet Protocol, IP, so far primarily known for carrying email and the world wide web, serves as a focal point for the integration of different transportation technologies: from ATM and Ethernet to residential access technologies like ADSL and cable modems. Complex, expensive telephone switches are being replaced by IP routers; complex tasks move into end-to-end applications that evolve just as fast as other PC applications. Instead of two separate communication infrastructures for voice and data, carrier as well as enterprise networks will only need to maintain one. The packet switching technology driving the Internet allows a better use of existing capacities and automatically finds low-cost routes. Begun in the mid-90s, the development of the base technologies has led to stable standards. In their continued refinement, TZI is playing an important role as a transfer-oriented research organization. Many manufacturers now offer interoperable products, in particular all well-known producers of telephony systems have expanded their product portfolio accordingly. Powerful networks and routers are available—all requirements for stable and efficient production operation are met. Although universal deployment, including full integration of voice and data communication up to the endpoints, will continue to remain a vision for some time, there are already a lot of opportunities in its use today – not just for early adopters. Usage of IP as the "new" switching layer by the providers, the integration of voice and data in corporate networks or even combined internet/telephony services offered by ITSPs are only a few of those. They offer new potentials for lowering costs, enable new value adds, and provide avenues for qualitative differentiation.
