There is a known bug and a known patch to fix it. I can't remember right now which one it is. Hello I would like to use nibblebilling for fraud prevention on international and premium numbers ( national or emergency calls should never be blocked and should still working even if the billing database is unavailable ) Unfortunately that never hangup my calls using standard dial plan *nibblebill.conf.xml* <configuration name="nibblebill.conf" description="Nibble Billing"> <settings> <!-- See http://wiki.freeswitch.org/wiki/Mod_nibblebill for help with these options --> <!-- Information for connecting to your database --> <param name="db_dsn" value="pgsql://hostaddr=127.0.0.1 dbname=xxxx user=xxxx password=xxxx"/> <!-- The database table where your CASH column is located --> <param name="db_table" value="accounts"/> <!-- The column name where we store the value of the account --> <param name="db_column_cash" value="cash"/> <!-- The column name for the unique ID identifying the account --> <param name="db_column_account" value="id"/> <!-- Default heartbeat interval.
