Zusammenfassung:	VIRTUAL PBX CALL PROCESSING METHOD A virtual PBX capability is provided to a group of user packet stations served by a packet switching system. The system establishes a virtual circuit between each distinct pair of stations in the group. The stations exchange signaling packets via the virtual circuits and respond to such packets by coordinating the initiation and disconnection of voice, data, or image calls. All call processing, including the provision of features such as call forwarding andautomatic callback, is accomplished by the stations without the aid of the switching system. A fraud prevention mechanism is included in the switching system to prevent unauthorized stations from communicating as part of the virtual PBX group.
