• Checks calls are charged at correct rate.
• Checks for call cost sum errors.
• Checks correct discounts have been applied.
• Checks overall sum values.
• Flags a series of warnings, including zero use , unknown call types and no configured tariff.

The reports can be viewed on screen, saved to a .csv file or exported to Excel.
