IP Austria’s flagship: IP Voice

As the first RTR-certified provider of Voice-over-IP services in all of Austria, we believed in a flourishing future 25 years ago. Today we stand exactly where long-established market players would like to take our place. Our network comprises a fully redundant VoIP infrastructure that connects all of Europe and large parts of the world.

In Austria itself, we have succeeded in returning a previously uncontested former state monopoly market to the people. We have formed partnerships with visionaries, technology enthusiasts and network experts to bring proven Austrian telephony quality to end users – that is exactly our mission at IP Austria.
