CDR File Module
Cdrfile is a module that receive a "chan.cdr" message (maybe from cdrbuild) and is writing the CDRs into a file.

List of available variables that could be used to construct a CDR record
Note: in order for a parameter to be available in the cdr, it has to be enabled in cdrbuild.conf.
The cdrwrite parameter is special, a boolean value of false will prevent the CDR from being written. This is to avoid generating CDR records for utility channels while still being able to track them.
- ${time} - UNIX time
- ${billid} - billing record id
- ${chan} - channel used
- ${address} - destination address
- ${caller} - username/number of the device that initiated/received the call
- ${called} - destination number
- ${callername} - caller id
- ${billtime} - billable call duration, starts from the point when the remote party actually answers the call
- ${ringtime} - total time of the call
- ${direction} - has a value of outgoing or incoming
- ${status} - disposition of the call
- ${reason} - reason for call disconnection
Configuration
cdrfile.conf:
[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
; Example: file=/var/log/yate-cdr.tsv
;file=
; tabs: bool: Use tab-separated instead of comma-separated if format is missing
;tabs=true
; format: string: Custom format to use, overrides default. Each ${parameter}
; is replaced with the value of that parameter in the call.cdr message
; tab-separated (.tsv)
;format=${time} ${billid} ${chan} ${address} ${caller} ${called} ${billtime} ${ringtime} ${duration} ${direction} ${status} ${reason}
; comma-separated (.csv)
;format=${time},"${billid}","${chan}","${address}","${caller}","${called}",${billtime},${ringtime},${duration},"${direction}","${status}","${reason}"
Set CDR billing
In many real-life situations CDR billing is done in seconds.
It's useful to set:
cdrbuild.conf
[general] resolution=sec
Converting call time
If you need a human and machine readable representation of the time column you can use the following AWK script:
awk 'BEGIN{FS="\t";OFS="\t"} {$1=strftime("%Y%m%d%H%M%S",$1); print $0}' /var/log/yate-cdr.tsv
The above assumes TAB separated format, the ${time} parameter is in the first column (the $1 positional parameter) and the CDR file is in its usual place.
Adapt the script as needed. You can make the date/time more readable by inserting separators in the time format.
