Asterisk: The Future of Telephony

cdr.conf

The cdr.conf file is used to enable call detail record logging to a database. Storing call records is useful for all sorts of purposes, including billing, fraud prevention, QoS evaluations, and more. cdr.conf 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:

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.

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.

safeshutdown

Accepts the arguments yes and no. Setting safeshutdown to yes will prevent Asterisk from shutting down completely until the buffer is flushed and all information is written to the database. If this parameter is set to no and you shut down Asterisk with information still residing in the buffers, that information will likely be lost.

scheduleronly

Accepts the arguments yes and no. If you are generating a massive volume of CDRs on a system that is pushing them to a remote database, setting scheduleronly to yes may be of benefit. Since the scheduler cannot start a new task until the current ...
