This is a nice tool for searching through and filtering the CDR's and present the results. I'd like to offer a some suggestions to improve it's functionality.
1 - export the results of a filtered, or non-filtered, search to a txt, csv or xml file format. This is big: sometimes we need to present the results to others.
2 - add a print function
3 - add a time zone offset
4 - either include the Cisco termination description and code or include a link to the Cisco doc listing the CDR code descriptions
btw: I had an initial problem similar to the "No CDR data returned" thread. Successful connectivity test followed by that error message. Waited a day, tried it again and bam, the data appeared. Timing is everything.
