<p>A call detail record (CDR) compare tool compares CDRs by a switch or other system providing billable telephone services to subscribers with billing system records to identify potential billing errors. For example, switch-generated CDRs that cannot be matched to a billing system record may represent a billable transaction that no subscriber was billed for. The compare tool reads some or all of the billing system’s records and, in turn, tries to match a CDR generated by a billable service system to one of the billing system records. If no match is found, the CDR represents a possible billing problem. Counters are maintained to count a number of matching records, non-matching records and the total number of records processed.</p> |
