Interpreting your Call Data Records (CDR’s)


From the Callroute portal’s reporting page, you can view your channel usage and historical calling information. You can also export your Call Data Records as a CSV file which is in a format based on the recommendations from the Federation of Communication Services.

This article explains the various fields shown in the CSV download, to ensure you can interpret your call data in a meaningful way.
