Abstract

See full text

A call processing and billing method where the two billing records generated for a redirected call are transmitted to the same billing center or to the same network of interconnected billing centers, and where the two billing records are correlated to generate a single billing record for use in billing the call. The method is extensible for calls that are redirected more than once.
