Abstract
A system for providing and managing IP telephone calls establishes separate and distinct call legs between IP-capable appliances and routers and between routers, and creates calls, changes calls, and manages telephony functions by joining and disjoining calls legs. In some instances one or more call legs disjoined from an active call are maintained as established to be joined later to other call legs to create other active calls. By managing EP calls as separate and distinct legs functions of intelligent, connection-oriented telephony networks may be simulated in IP telephony systems. The management is provided by software running on processors coupled to routers in the IP network.
Claims17
A system for simulating connection-oriented telephony functions in an IP network, comprising:
- two or more IP routers interconnected with two or more call appliances on the network;
- and
- software managing setup and execution of IP calls between call appliances through the routers;
- wherein IP calls are managed by the software by setting up separate and distinct end node legs between call appliances and routers, and separate and distinct intermediate legs between routers, and then joining and disjoining legs to establish voice communication and to provide telephony functions.
A method for simulating connection-oriented telephony functions in an IP network, comprising steps of:
- (a) interconnecting two or more IP routers with two or more call appliances on a network;
- (b) setting up separate and distinct end-node call legs between call appliances and routers, and separate and distinct intermediate call legs between routers;
- and
- (c) joining and disjoining legs to provide telephony functions.
A method for establishing an IP telephone call from a first IP-capable appliance through first and second IP routers to a second IP-capable appliance, comprising steps of:
- (a) setting up a separate and distinct end-node call leg between the first appliance and the first router;
- (b) setting up a separate and distinct end-node call leg between the second appliance and the second router;
- (c) setting up at least one separate and distinct intermediate call leg between the first and second IP routers;
- and
- (d) joining the call legs to establish voice communication.
