  • Method and apparatus for automatic inter-domain routing of calls
    Patent number: 7764618
    Abstract: A method and apparatus for inter-domain routing of calls in a network, where the network represents a first wide area network. A routing node of the network advertises its access to a range of addresses in a second wide area network and a cost for access to the range of addresses to all adjacent nodes in the network. Each of the adjacent nodes inserts an entry in its own routing table associating access to the range of addresses in the second wide area network with the network address of the routing node and the cost for access. Each adjacent node then modifies the cost for access by adding its own cost and advertises its access to the range of addresses in the second wide area network and the modified cost for access to all of its adjacent nodes.

  • Virtual private networks for voice over networks applications
    Patent number: 7120682
    Abstract: A method for providing virtual private networks for voice over data network users. A location server is provided that has more than one routing information database. A virtual private network is defined within that location server for each of the routing information databases. As registration information from gateways is received, they are associated with the appropriate virtual private network.
