CDR Processing for UK Telecoms Resellers
Turn call data into bills automatically. Support for 85+ UK carrier formats.
What is CDR processing?
A call detail record, or CDR, is the data your carrier records for every call, text or data session one of your customers makes. Carriers do not stream this per call. They batch it into daily or monthly files, which the billing platform then turns into something you can charge for.
The platform collects files from your carriers, converts each carrier format into one common shape, applies your tariffs and checks every call for errors before invoices go out.
For a UK reseller, that replaces hours of spreadsheet work each month with a billing run that takes minutes. SAFE supports 85+ CDR formats from UK carriers and wholesalers, including Gamma, BT Wholesale and the major VoIP providers, and flags unusual usage before it reaches your customer.
Accurate CDR handling also keeps you on the right side of UK telecoms billing rules. Ofcom expects providers to bill customers correctly for the services they actually used, and SAFE's checks make that auditable rather than something you have to take on trust.
No More Spreadsheets and Manual Work
Hand-processing CDRs is slow, and a single mistake can mean an under-billed customer or a query you have to chase. SAFE takes the whole job off your desk:

How CDR Processing Works
- 01
Automatic Collection
SAFE pulls CDR files from your carriers by SFTP, API or email wherever the carrier supports it. A few carriers only release CDRs through a manual portal, in which case files can be uploaded into SAFE once downloaded.
- 02
Standardisation
Each carrier uses its own file layout. SAFE converts them all into one common format before rating begins.
- 03
Rating and Checking
Your tariffs are applied to every call. The system flags unusual usage and pricing that does not look right, so you can spot problems before billing.
- 04
Reporting
Rated calls are prepared for invoicing. Detailed reports give you a clear view of revenue, margins and any flagged items before the run goes out.
Smart Error Detection
Processing CDRs is one job. Catching the records that look wrong before they hit a customer invoice is another. SAFE does both:
Unusual Usage Alerts
Flags call patterns that might indicate fraud or provisioning errors.
Rating Issues
Highlights calls where pricing may not have applied correctly.
Carrier Reconciliation
Compares processed calls against carrier invoices to find discrepancies.
Pattern Analysis
Compares with previous billing periods to spot unexpected changes.
Benefits of Automated Processing
Save Time
Free your team from manual CDR tasks so they can focus on more important work.
Better Accuracy
Reduce human error with automatic processing and systematic validation.
Protect Revenue
Catch and bill for every call. Unrated calls mean lost revenue.
