ABSTRACT:
A network of processing devices is arranged to communicate by packets having an addressing header and a data portion. Within the network, audio telephony is implemented. A signaling packet is sent from a source processing device to a central location identifying a destination processing device. A signaling packet is sent from the central processing location to the destination processing device identifying the source processing device. A packet is supplied from the central location to the sourcing processing device identifying an address for the destination processing device, whereafter packets containing digitized audio signals are transmitted over said network directly between the source processing device and the destination processing device.
