Local Usage Details (LUDs) are the logged records of local calls generated by a telephone switch. Unlike toll or long-distance records which have always been itemized for billing, local calls were traditionally billed at a flat rate, making LUDs a specialized report. Telecom investigators and law enforcement request these records to trace local communication patterns during criminal investigations.
