CDR And CEL

GABPBX supports both Call Detail Records and Channel Event Logging.

CDR

CDR records call summary information. Modules live under:

cdr/

Module	Purpose
cdr_csv	Write CDRs to CSV.
cdr_custom	Custom text CDR format.
cdr_manager	AMI CDR events.
cdr_odbc	ODBC CDR backend.
cdr_pgsql	PostgreSQL CDR backend.
cdr_radius	RADIUS CDR backend.
cdr_realtime	Realtime CDR backend.
cdr_sqlite3_custom	SQLite3 custom CDR backend.
cdr_syslog	Syslog CDR backend.
cdr_tds	FreeTDS CDR backend.
cdr_adaptive_odbc	Adaptive ODBC CDR backend.
cdr_mysql	MySQL CDR add-on.

Choosing CDR Or CEL

Use CDR for billing-style call summaries.

Use CEL when you need event-level visibility:

• channel creation
• answer
• bridge enter/leave
• transfer behavior
• hangup cause flow
• user-defined events

Many deployments use both.
