Abstract:
1. A system for simulating connection-oriented telephony functions in an Internet Protocol (IP) network, comprising: a first IP router in the network coupled to a first Internet-capable call appliance and to a second IP router; a second Internet-capable call appliance coupled to the second IP router; and software executing from a digital storage medium, the software enabled to control specific functions of the first and second IP router; a call waiting server connected to the second IP router; wherein a first call placed from the first Internet-capable call appliance is connected to the second Internet-capable call appliance managed by the software creating and joining separate and distinct intermediate call legs between the first call appliance, the first IP router, the second IP router and the second Internet-capable call appliance and a second call placed to the second Internet-capable call appliance, when the second Internet-capable call appliance is in use with the first call, is redirected from the second IP router to the call-waiting server by the software creating a distinct and separate call leg for the second call from the second IP router to the call-waiting server, the call-waiting server and the IP router cooperate to provide an indication at the second Internet-capable call appliance that there is a call waiting and upon completion of the first call, the end node call leg associated with the first call to the second Internet-capable call appliance is destroyed, and a new end node call leg is established from the second IP router to the second Internet-capable call appliance, the new leg associated with the second call, thereby completing the second call to the second Internet-capable call appliance.
