I had recently completed a hobbyist PowerShell script that could retrieve the call records of a selected duration from your TollFreeForwarding.com account and create a peak hour pivot table report. Thanks to the API provided by TollFreeForwarding.com at https://tollfreeforwarding.com/api/
Source code and dependencies detail available at : https://github.com/argentolee/TollFreeForwardingPeakHourReport
