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.

Abstract: A method of evaluating automatic message accounting records associated with telephony calls that originate at a local exchange carrier telephony office and that are routed over an inter-exchange carrier telephony facility is disclosed. The method comprises collecting originating automatic message accounting records associated with the originating local exchange carrier telephony office, and collecting terminating automatic message accounting records that correspond to the originating automatic message accounting records. A first portion of the terminating automatic message accounting records have a terminating access code and a second portion of the terminating automatic message accounting records have a local termination code.
