gaspar, maybe we should start over and find out what you actually need help with.
Is your switch outputting data, is the software collecting it, is the data readable, or do you just need help interpreting it?
If you're not getting data into the software, have you checked the settings on the PBX, is the cabling ok (the old "is it plugged in and turned on"), are the call accounting software settings correct, especially the type of switch data it's set to read?
If you are getting data into the software, are you able to retrieve information? From this specific extension or from any extension?
Are you looking for info the switch doesn't output? CDR data usually includes at a minimum start time and duration, and the source and destination, but it won't tell you if a call was actually made by someone who "borrowed" another user's desk.
It's difficult to know where to look next without more information. What problem are you having and what have you tried so far?
