PSTN Call Statistics via Microsoft Graph API or PowerShell

We also need this information for call reports and stats. Unlike many other missing features, this doesn't seem to be acknowledged in any roadmaps. It's a requirement to provide metrics and analytics on call information, and the reports that you can download from the old SfB admin panel are pretty much unusable - you have to manually download, unzip, convert the document from tab delimited and then try to make sense of it. For a weekly call report it's just not plausible.
