This object sets how frequently the chassis performs intermediate accounting collection, finalizing and writing out interim CDRs, whether hourly, every two hours, every three hours, and so on. An admin balancing billing-data timeliness against system/collection overhead would choose a shorter interval for more real-time billing visibility, at the cost of generating and transmitting more frequent accounting files. A carrier wanting near-real-time revenue visibility might set this to hourly(4) rather than a longer interval, accepting the extra file-generation overhead for fresher billing data.
