The cdrcombine module enables the writing of a single CDR entry per call instead of multiple entries, one for each call leg (one for the incoming leg and one or more for outgoing leg(s)).
This module was added in SVN revision 5394.

By default yate writes a CDR entry for each leg of a call. You usually have two call legs: one between the caller party and yate server and the other one between yate server and called party. This module enables you to write a single entry in the CDR log file/database table.


Operation on CDR

This modules catches the call.cdr messages for operations "initialize", "update" and "finalize" and emits call.cdr message with operation "combine" at the end of the call.

Format for information

Unified information for call

Fields identifying a call:

  • time
  • billid
  • caller
  • called
  • status

Call leg specific information

The following fields are call leg specific:

  • chan
  • address
  • billtime
  • ringtime
  • duration
  • reason


There is no configuration file for cdrcombine module. In order to use set "combine" option to true in cdrfile.conf.

How to use

  • In cdrfile.conf set:
; file: string: Name of the file to write the CDR to
; You should check that this file is log rotated - see /etc/logrotate.d/yate

; combined: bool: Use combined CDR for all legs of a call

; comma-separated (.csv), combined=true
format=${time}, "${billid}", "${chan}", "${address}", "${caller}", "${called}", ${billtime}, ${ringtime}, ${duration}, "${status}", "${reason}", "${out_leg.chan}", "${out_leg.address}", ${out_leg.billtime}, ${out_leg.ringtime}, ${out_leg.duration}, "${out_leg.reason}"
