CDR Processing

Overview

CDRs (Call Detail Records) are the usage records used to calculate call charges. Correct CDR supply and matching are essential for accurate invoicing.

Core Process

1. Import CDR files from carriers/providers.
2. Validate format and date windows.
3. Run matching against customer numbers and tariffs.
4. Review mismatches in billing errors.
5. Re-run checks before requesting bill production.

Common Issues

CDRs not matching

• Check the number exists and is active for the call date.
• Check tariff assignment and effective dates.
• Check provider format mapping rules.

Unexpected call charges

• Recheck tariff section and rate band.
• Confirm destination/type categorisation.
• Confirm discount plans are applied as expected.
