Asterisk cdr.conf how to set up simple billing

i have asterisk16 on openwrt 19.7 everything works good but i need simpliest billing (Call Data Records).
what shood i put in cong in order to make it work?
i tried to install all the cdr pokets but there is still no file

So actually all you need to do is install
opkg install asterisk16-cdr asterisk16-cdr-csv
dont forget to delete cdr.conf befor instalation cause it will wright new one
now all the calls in /var/log/asterisk/cdr-cvs/Master.cvs

But now i am thinkin about sqlite3 and dont know how to configure that one , also is there any free client for windows for sqlite3 ?
