CDR Reporting Tools for Asterisk 1.4.0?

Are there any great CDR reporting tools available to use with Asterisk 1.4.0? I’ve really seen one on AsteriskGuru.com under Tools, but I seen mixed responses about the tool. Any info and URLs to any good CDR reporting tools would be great, where I can generate reports and know what a specific CALLING number (or CALLED number) has been doing. Thanks!

I am making one. The idea is to report information, not only from CDR but other sources as well I have a full reporting for people using Issabel call center based on Asterisk, but moving to go directly for Asterisk users. It is Open Source
