# Viewing CDR Reports
Below is a screenshot of the CDR Call Reporting page.
You can change dates, and change the amount of detail shown with the simple view of the CDR records, and the advanced view of the CDR records.
# Changing the CDR Date Range on the Report
By default, the page will load the last 7 days history of Cisco Callmanager CDR records. You can change the date range to view older records.
# Suspected Spam or Robocaller Report - Low Duration CDR Calls Report
Call Accounting data can help you find suspected robocallers and block those callers. You can filter by low duration calls over a time period. Let's say the same number has called your system 30 times in the last 30 days, but the average call duration is only 5 seconds. That is a good indicator of a robocall, spam or unwanted caller.
Once you see these patterns, you can expand the record to see the full details of the call, and take action like blocking that calling number.
# Live Streaming of Cisco CDR Call Data
You can also view live streaming of CDR records as they come in. This can be useful for debugging or monitoring purposes.
