Abstract:
A method of enforcing network-centric control over access to a selected destination point in a network adapted to complete calls through a switched telephone network to the selected destination point in response to a call completion request from an origination point in the network, comprising the steps of:a) establishing a first connection between a user at the origination point and an authentication server in the network; b) authenticating the user in an authentication session over the established first connection; c) selectively authorizing the user for access to the selected destination point; d) substituting an origination calling line identification CLID with an authorized CLID in a call completion request associated with a second connection, and enabling a destination SSP to selectively complete a second connection to the selected destination point only if the authorized CLID is included in the call completion request; and e) preventing network elements from completing a subsequent connection to the selected destination point unless a user is authenticated and authorized anew.
