This is a call detail recording (CDR) module for asterisk and is used to store records to any database yada supports (currently MySQL, Oracle, PostgreSQL, SQLite3). If the database is not available, it can queue records to both memory and disc for later playback without worry of losing records.
Version 003 adds userfield parsing, sponsored by voipGATE. Using this feature you can add custom columns to the database schema and populate them via column=value pairs passed to SetCDRUserField. See the README for more information and examples.
Current version is 008 released on 01/15/08 (signed by).
