Estimated generated call revenue


The table below explains in detail the steps of a Splunk Enterprise or Splunk Cloud Platform search to help estimate a total daily call revenue stream. For more information, review the use case monitoring key telecommunications service metrics.

Some commands, parameters, and field names in the searches below may need to be adjusted to match your environment.  In addition, to optimize the searches shown below, you should specify an index and a time range when appropriate.

Splunk recommends that customers look into using data models, report acceleration, or summary indexing when searching across hundreds of GBs of events in a single search. The searches provided here are a good starting point, but depending on your data, search time range, and other factors, more can be done to ensure that they scale appropriately.   

Splunk Search Explanation
| sourcetype=<call detail records> Search only your telephony data.
| eval _time = start Extract the timestamp and put it in a field called "start".
| lookup <cdr disposition mapping file> disposition

Enrich the search results with clearer descriptions of the dispositions.

If your lookup file does not contain the disposition column, adjust the search to match the names in your lookup.

| search disposition="ANSWERED" OR billable > 0 Search for billable call events, identified with a disposition of ANSWERED or where the billable field has a value greater than 0.
| rex field=dst "(?<dstCountry>\d+)(?=\d{10})"

Extract the destination (dst) country code.

This example assumes that the country code is what precedes a 10 digit number.

| lookup <country code to name mapping file> phoneCode AS dstCountry OUTPUTNEW countryName as dstCountryName ISO2 AS dstCountryCode rateFirstMinute rateMinute

Enrich the results by adding a country name, iso code, and billable rates. based on the dstCountry field extracted.

If the column names in your lookup file differ from those shown here, adjust the search to match the names in your lookup.

| fields _time accountcode src billable dstCountryCode rate* Return only the fields shown.
| convert dur2sec(billable) AS calculatedBillableS Convert the value in the billable field to a numerical value in seconds without replacing the original values.
| eval billableMinutes = calculatedBillableS / 60 Calculate billable minutes by dividing calculated billable seconds by 60.
| eval billableMinutes = ceiling(billableMinutes) Round billable minutes to the next highest integer.
| eval billableMinusOne = billableMinutes - 1 Subtract 1 from the total billable minutes.
| eval totalBillable = rateMinute + (billableMinusOne * rateMinute) Calculate the total billable rate per call
| stats sum(totalBillable) AS CallRevenue Sum and display the total billable revenue.
