CDR Reports working, but no file


I had a problem with CDR reports to get working, and I solved it by disabling digium module. Now I have a problem with the actual CDR file, I can get the CDR report in the FreePBX, Reports -> CDR reports, but there is no file in the var/log/asterisk/cdr-csv ??

FreePBX is not configured to send to the CDR log files. You will have to set that up yourself.

Okay, can you help me with a link or something to start with?
