CDR Processing

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:

  • Collects call records from your carriers automatically
  • Works with 85+ CDR formats from UK carriers
  • Smart rating that applies the right prices every time
  • Finds errors and unusual patterns before they reach invoices
  • Creates detailed pre-billing and post-billing reports

How CDR Processing Works

  1. 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.

  2. 02

    Standardisation

    Each carrier uses its own file layout. SAFE converts them all into one common format before rating begins.

  3. 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.

  4. 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.

Common Questions

What is CDR processing?
CDR processing turns raw call detail records from your carriers into customer invoices. The system collects the files, converts each carrier format into one common shape, applies your tariffs, checks for errors and produces ready-to-send bills.
Which UK carriers does SAFE support?
SAFE reads 85+ CDR formats from UK carriers and wholesalers, including Gamma, BT Wholesale and the major VoIP providers. New formats are added when a customer needs one.
How does the platform spot billing errors?
Every call is checked against your tariffs and against the customer’s previous usage. Anything that looks unusual, mis-rated or out of pattern is flagged for a quick review before invoices go out.
How often are CDRs processed?
On higher packages, files are collected and rated as soon as they arrive from your carriers, so your team and the customer portal see the latest usage continuously. The Startup package runs a single monthly processing cycle, which suits resellers billing on a clean month-end pattern.
Does this help with Ofcom and tax obligations?
The platform produces UK-compliant invoices and a full audit trail. Rated data supports your reporting duties to Ofcom as a communications provider and to HMRC for VAT.
