Internet Service Provider since 1995

Pioneer in Cloud Communications
CNT adopted Voice over IP as early as 2001, before SIP became an established standard.

History
1995: The Beginning of Commercial Internet Use
At a time when the commercial use of the internet was still in its infancy, CNT, in collaboration with IBM, provided internet access via leased lines and site networking for business customers across Germany. Just a few months later, CNT took over the support of IBM AS/400 partners in Southern Germany as well as renowned clients like Daimler – a true pioneer in this field.
