I have upgraded PBX to Asterisk and now CDR files are not created. It looks that such logging is disabled:

Connected to Asterisk currently running on pbx2 (pid = 5824)
Verbosity is at least 3
pbx2*CLI> cdr show status
Call Detail Record (CDR) settings
    Logging:                    Disabled
    Mode:                       Simple

Asterisk shows that CDR modules are loaded:

pbx2*CLI> module show like cd
Module                         Description                              Use Count

How to enable creating CDR csv files?

We had to follow some more steps.

We needed some CDR logging ASAP and our AsteriskNOW server did not have modules for MySQL CDR logging. We would not install new packages in a running, highly requested production server, so we relied on CSV logging.

To enable it is easy. First, we edit /etc/asterisk/cdr.conf (if it does not exist, we create it) adding a [csv] section. We added some more configuration on it as below, but apparently the important thing is to create the section.


Then, we edited /etc/asterisk/modules.conf for loading the cdr_csv.so module:

; Loading cdr
load => cdr_csv.so

For enabling the logging immediately without restarting Asterisk, we called asterisk -vvvr and loaded the module:

voip*CLI> module load cdr_csv.so

Now every call is logged in /var/log/asterisk/cdr-csv/Master.csv.

It took us some time to get it working. This page proved itself as a useful reference.


It seems there was bug in Asterisk Now. It needed /etc/asterisk/cdr.conf which was absent.
