Abstract

A telecommunications service controls and monitors telephone calls by storing at a service control point (SCP) restricted telephone numbers and priority telephone numbers. Upon receiving call data relating to a call between a subscriber telephone number and an outside telephone number, the SCP determines whether the outside telephone number matches the restricted or priority telephone numbers. When the outside telephone number matches a restricted telephone number, the call is terminated and the SCP stores the call data. When the outside telephone number does not match a restricted telephone number, or matches a priority telephone number, the call is connected. The SCP transmits stored call data to a service management system, which is accessible by the subscriber via the Internet or an interactive voice response, for generating reports. The service further includes time schedules for implementing call restrictions and personal identification number for bypassing call restrictions.
