Patent
CA 2311897
An apparatus and methods enforcing network-centric control over access to a selected destination point in a switched telephone network are presented in which, a user seeking access to the selected destination point is authenticated in the network on a separate telephone connection prior to authorizing the user to access the selected destination point. An on- the-fly generated authorized calling line identification is associated with an origination point from which the user initiates the call completion request to enforce access control. The call completion is monitored end-to- end and the resulting telephone session is audited at the signaling and payload levels providing management support personnel with information substantiating the release of the call in case of misuse or intrusion.
