Asternic CDR Reports will let you run reports over your Asterisk PBX call detail records, but with a different twist. Instead of a big pile of unorganized records, you will see them grouped by user and call direction. You will know how many calls each of your users/extensions made or received, with call durations, ring times. There are several distribution reports: per day, week, month, day of week. There is also a detailed report that you can export or search for particular records. You also will have a link to download or listen to recordings if they are available in your system. All from your web browser, without the need to install anything on the client side. Development edition includes full source code and can be installed in up to 5 within your organization.
