How the Ring Central counting inbound and outbound calls ?

I am getting company log data using below Callout URL

https://platform.ringcentral.com/restapi/v1.0/account/~/call-log?view=Simple&dateFrom=2020-05-06T00:00:00.000Z&dateTo= 2020-05-06T23:59:00.000Z&page=1&perPage=1000

I am counting the inbound calls based on the agent phone number and Extension number and outbound calls based on the agent phone number.

but the count is not matching with live report inbound and outbound count.

In which criteria ring central is counting inbound and outbound calls count in a live report.
