;
; Asterisk Call Detail Record engine configuration
;
; CDR is Call Detail Record, which provides logging services via a variety of
; pluggable backend modules.  Detailed call information can be recorded to
; databases, files, etc.  Useful for billing, fraud prevention, compliance with
; Sarbanes-Oxley aka The Enron Act, QOS evaluations, and more.
;

[general]

; Define whether or not to use CDR logging.  Setting this to "no" will override
; any loading of backend CDR modules.  Default is "yes".
;enable=yes

; Define the CDR batch mode, where instead of posting the CDR at the end of
; every call, the data will be stored in a buffer to help alleviate load on the
; asterisk server.  Default is "no".
;
; WARNING WARNING WARNING
; Use of batch mode may result in data loss after unsafe asterisk termination
; ie. software crash, power failure, kill -9, etc.
; WARNING WARNING WARNING
;
;batch=no

; Define the maximum number of CDRs to accumulate in the buffer before posting
; them to the backend engines.  'batch' must be set to 'yes'.  Default is 100.
;size=100

; Define the maximum time to accumulate CDRs in the buffer before posting them
; to the backend engines.  If this time limit is reached, then it will post the
; records, regardless of the value defined for 'size'.  'batch' must be set to
; 'yes'.  Note that time is in seconds.  Default is 300 (5 minutes).
;time=300

; The CDR engine uses the internal asterisk scheduler to determine when to post
; records.  Posting can either occure inside the scheduler thread, or a new
; thread can be spawned for the submission of every batch.  For small batches,
; it might be acceptable to just use the scheduler thread, so set this to "yes".
; For large batches, say anything over size=10, a new thread is recommended, so
; set this to "no".  Default is "no".
;scheduleronly=no

; When shutting down asterisk, you can block until the CDRs are submitted.  If
; you don't, then data will likely be lost.  You can always check the size of
; the CDR batch buffer with the CLI "cdr status" command.  To enable blocking on
; submission of CDR data during asterisk shutdown, set this to "yes".  Default
; is "yes".
;safeshutdown=yes
