A telephone call control system includes a database (20) containing user identifiers and call control limitations assigned to the user identifiers. Call control limitation may include budgetary, time, geographic (e.g. area code or city and/or country codes), and other limitations to a call. A telephone line (17, 19) is subscribed to the system, and users of the line are provided user identifiers which may have one or more of the call control limitations. When making an outgoing call, the telephone network (14) communicates with a server (12) which requests the user to enter the user's identifier, e.g., a dialling code or voice print. It is then determined which, if any, call control limitations, are placed upon the user and whether and for how long the call can be connected. In addition, the system has call logging features. The disposition of calls are recorded in a log preferably accessible via the Internet. |
