Call Detail Recording is the log generated by a PBX or telecom switch for every phone call passing through it. It captures the metadata of the transaction, including the source and destination numbers, start time, duration, and the specific trunk used. Telecom providers and IT departments use these records for billing, capacity planning, and auditing abuse.
