Abstract
A call management system is provided to manage the use of specified wireless telephones in order to limit or manage their use for unofficial calls and to report on official as well as unofficial uses. Calls originated from or directed to a controlled wireless telephone are routed to a call management center from a wireless central office. The call management center determines whether the call is approved by consulting a database of approved telephone numbers. If the call is approved it is completed normally. If the call is not approved, the caller is prompted to provide an access code. The call is completed if the access code matches a predetermined security code. Customizable exception reports are generated to reflect unofficial usage, incorrect access attempts, and other detailed information concerning the use of the specified wireless telephones.
