CDR or CDR CUSTOM

Hello,

I configure my Asterisk to see the CDR, in / var / log / asterisk / cdr_csv it is OK
On the other hand I wish to modify the content Master.csv how do I then do?

OR

How to activate csv_custom because CLI tells me it’s OK:
Sip * CLI> cdr show status

Call Detail Record (CDR) settings

Logging: Enabled
Fashion: Simple
Log unanswered calls: No
Log congestion: No

  • Registered Backends

    Csv
    Cdr-custom

On the other hand nothing fits in / var / log / asterisk / cdr-custom
An idea ?

thanks in advance
