I have been testing CDRTool and get the following message in the log files when browsing to www.example.com/scripts/ratingEngine.php: Cannot instantiate non-existent class: ratingtables in /var/www/CDRTool/scripts/ratingEngine.php Is this because the non commercial version of CDRTool does not provide rating or is it something I have done wrong in the setup? Any advice would be appreciated. Regards Cameron
