Delator is a telephone/PBX call accounting system. It works with a PBX Lucent Definity G2 and a serial connection to store information in a PostgreSQL database. It has a Web interface which can give monthly reports of the use and cost of each call, from what extension each call was made, what number was called, etc.

Delator (plural Delatores) is Latin for a denouncer, i.e. who indicates to a court another as having committed a punishable deed.
