Реферат: Providing Voice Over Internet Protocol networks includes attempting to authorize a call from a user made to a number, routing the call, after the call is authorized, to a remote location (108), and setting up call signaling at the remote location between the user (114) and a destination of the call (112) so that media content of the call flows between the user and the destination but not through the remote location (134).
