Abstract: The invented method and system for enabling and controlling telephony over existing networks, e.g. ATM networks, the Internet or other data networks, uses essentially distributed control processing employing intelligence in the typical end-user devices, e.g. workstations or personal computers. Parallel use of a real-time channel (to provide the needed direct voice communication) and a control channel (for basic services like connection buildup and termination and for supplementary services) essentially established by and from the users's workstations (and in principle excluding the PBXs) allows implementation of practically any imaginable function.
