Abstract
Telephone call routing in networks is provided by forwarding routing data other than origination identification and destination identification in-band with calls, and using the in-band data at call destinations to do further routing. In some embodiments negotiation is accomplished between routers at different points in the network based on the in-band routing data. Practice of the invention extends to intelligent telephony networks and as well to simulated telephone calls between computers in wide area data networks, such as the Internet and Intranets.
