The Sonic Telecom GmbH was founded as an european branch of the Sonic Telecom Ltd./Virginia USA at the 8th of September 2000 at Frankfurt/Main. This happened together with the branches in France, Great Britain and Singapore under the roof of the Sonic Telecom Holding in Ireland. A goal was it to create an international selling and support structure for the world-wide to be developed H.320 video over ATM network (= VIDEO1). More and more the German GmbH was thereby established as the development and support center. Thus the until today singular VIDEO1 Dial-In procedure, based on an own developed Dial-In plattform, was developed here.
