CPC Analytics should keep CDR data for 52 weeks without any settings.
In my lab i am not able to get the 52 weeks of data from CPC Analytics, I only get 5 weeks of data history.
I have attached a print screen.
Analytic has been installed for nearly 2 years, the strange thing is that 52 weeks of data seems to be there in the main Detailed Analaytis graph at the top but its not there in the bottom report. (see print screen)
I generated the bottom report by clicking on the links just bellow the graphs and theres no data before decembre 15.
However, when you look at the top Detailed Analaytis graph you see that theres data prior to december 15
I tried different types of report, for different directory number and I can never go before december 15 in the bottow report.
The Top Detailed Analaytis graph always has data well before december 15.
