Asterisk: The Future of Telephony, 2nd Edition

cdr.conf

The cdr.conf file is used to enable call detail record logging to a flat file or a database. Storing call records is useful for all sorts of purposes including billing, fraud prevention, QoS evaluations, and more. The cdr.conf file contains some general parameters that are not specific to any particular database, but rather indicate how Asterisk should handle the passing of information to the database. All options are under the [general] heading of the cdr.conf file:

enable

Accepts the arguments yes and no. Specifies whether or not to use CDR logging. If set to no, this will override any CDR module explicitly loaded. The default is yes.

batch

Accepts the arguments yes and no. Allows Asterisk to write data to a buffer instead of writing to the database at the end of every call, to reduce load on the system.

Warning

Note that if the system dies unexpectedly when this option is set to yes, data loss may occur.

size

Sets the maximum number of CDRs to accumulate in the buffer before posting to the backend CDR storage systems. This setting only takes effect if the batch setting is set to yes. This setting defaults to 100 records.

time

Accepts an integer (in seconds) as its argument. Sets the number of seconds before Asterisk flushes the buffer and writes the CDRs to the database, regardless of the number of records in the buffer (as defined by size). The default is 300 seconds (5 minutes).

scheduleronly

Accepts the arguments yes and no. If you are generating a massive volume of CDRs on a ...
