Abstract
The present invention is directed to a method and apparatus for accessing a packet node or device through a circuit-switched network. Circuit-switched technology, such as local number portability techniques, and packet-switching technology, such as soft switches, are integrated in a network. As such, calls may originate from a circuit-switched network and terminate in a packet-switched network.
