ABSTRACT:
Call detail service is provided using a trigger that only activates after the disposition of a telephone call is known, for example, a T-Busy and/or a T_NoAnswer. When a telephone call encounters the T-Busy or T_NoAnswer trigger a terminating central office switch attempts to complete the call. If the call is not completed because it is busy or not answered, the information related to the call is sent to a service control point. The service control point creates a call information record. The call information record is sent to a service management system that used the call information record to create a call detail report. Using the T_Busy and/or T_NoAnswer triggers eliminates the need to collect data for every telephone call to determine which calls are not completed because they are not answered or busy. As a result processing complexity and storage requirements are significantly reduced.
