A free online tool to determine maximum concurrent calls in an CDR dump file

Simply submit your CDR file in csv format. Our servers will analyze the data and send you a report. You data is always kept private, never shared and is deleted right after the report is sent. You can submit an CDR file without names, numbers or any other identifiable private data.


Plese enter your email for the report. Select your .csv file with either a 'Start DateTime and Duration', or 'Start DateTime and End DateTime' columns. The first line should contain column headings. You will receive your report when it is processed in the order received, typically within several hours. The service is entirely free as a trial while we continue to build our advanced CDR Analytics tools.
