Hi Jacky, looks like your rating engine is not running. Did u install and start it? I am using debian packages for cdrtool and it is automatically installed. If u used same, all u must do is edit the /etc/defaults/cdrtool to enable both ratingengine as well as memcached and then start cdrtool with /etc/init.d/cdrtool start. Hope that helps. Cheers, DanB
