Abstract

A system of evaluating automatic message accounting records associated with telephony calls is disclosed. The system includes correlation logic to collect originating AMA records having an originating call code to identify a record of an originating long distance call and further to collect terminating AMA records that correspond to the collected originating automatic message accounting records. The system also includes evaluation logic to determine when a call may be by-passing terminating access charges by identifying calls that have been correlated with an originating AMA record having the originating code and with a terminating AMA record having a local termination code.
