Hi @UtauyoNASE
If you’re an admin, you could open the Teams Admin Center, and go to Analytics & reports. Then select Usage reports and run the call reports for the last three months.
Besides, you could use Office 365 eDiscovery, you need to first configure the feature. You can then retrieve and export call history data. You can use this tool to retrieve data from chats and meetings, as well. For more information, see:
