We need someone to create a simple CDR analysis tool that will show graphs of usage (with variable time-scales we specify) so that we can import customers data into MySQL and see minimum, average, and peak activity for the given time frame. Usage should be found at all times, not just in 5-minute slices (if 30 people call in for 30 seconds, this needs to register in some fashion on the graph).
Data will be a simple table of start times and end times of each call.
Something like this should just have a start and end date field from which the graphs are made (minimum in the X-minute slice, average, & max). Something that looked similar to Cacti output would be good (though I'd guess that RRDTool may not be the best tool due to its data loss over long periods).
