CDR -> Export CDR/CMR
Enter date range
Check CDR only
Export to file
Import text file into excel
Sort by comma delimited
delete columns that are not relevant
the time column will need to be converted
right click cell -> format cell -> select time format
convert time using formula =(A2-18000)/86400+date(1970,1,1) Where "A2" is the cell <-- this is the formula to convert to EST time
Good luck and a word of caution this is going to pull lots of data depending on your environment I wouldn't recommend pulling more than a couple of weeks.
HTH,
