CDRcombine Module

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 the called party. Cdrcombine module unifies the information about the call and the 2 call legs and writes a single entry. This entry can be written in a file or in the database.

Using this module makes it easier to follow the call logs, but it's only recommended for simple setups.

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

Configuration

There is no configuration file for cdrcombine module. In order to use set combine option to true in cdrfile.conf or set query_combined in register module [call.cdr] section.

How to use

Writing call logs to a file

• Make sure the cdrcombine, cdrbuild, and cdrfile modules are loaded.

• In cdrfile.conf set:

[general]
; 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
file=/var/log/yate-cdr.csv

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

; 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}"

Writing call logs to the database

• Make sure the cdrcombine, cdrbuild, and register modules are loaded.
• In register.conf [call.cdr] section uncomment cdr_combined or set your own query:

cdr_combined=INSERT INTO cdr VALUES(TIMESTAMP 'EPOCH' + INTERVAL '${time} s','${chan}',\
 '${address}','${caller}','${called}',INTERVAL '${duration} s',INTERVAL '${billtime} s',\
 INTERVAL '${ringtime} s','${status}','${reason}','${out_leg.chan}','${out_leg.address}',\
 INTERVAL '${out_leg.billtime} s',INTERVAL '${out_leg.ringtime} s',\
 INTERVAL '${out_leg.duration} s','${out_leg.reason}'
