[OpenSER-Users] CDRTool help?

Hi, can anyone provide any advice on getting CDRTool to work? I have installed CDRTool 6.0 on a Debian Linux system 2.6 Kernel with Apache/2.2.6 (Unix) PHP/5.2.5 I am attempting to get it to work with OpenSER only (I have commented out the Asterisk and sip_trace sections in global.inc) and I am recieving the error: Error initializing CDRTool datasource It seems that in callsearch.phtml "$cdr_source" is not being set, but I dont understand why not and I am not sure how to get more debugging info out of the whole thing (Im not used to PHP), I dont see any errors in the syslog :( With regards global.inc, I believe all database usernames and passwords are setup and have successfully tested connecting to all databases with this data - and I believe all db_class sections have the corresponding sections as required (the username, password, tablename etc). thanks for any help! Andy.
