A data analyzer incorporating an expert system is provided for call records which cannot be validated. The data analyzer can apply default or amended data, or can output invalid data to a suspended process awaiting updated reference information. Unfixable data is output to a sump for management purposes. A pricing and charging engine processes data already sorted according to billable entity and incorporates further data analysis for dealing with data invalid by reason of pricing and charging related information.
