Export Microsoft Teams Direct Routing Calls

Summary

This script exports the log of direct routing calls for a given duration.

Permissions

The PowerShell version of the script requires Microsoft Entra ID App Registration with the Application Permission as follows:

1. CallRecord-PstnCalls.Read.All
2. CallRecords.Read.All

Note: You can skip this step, if you are planning to use CLI for Microsoft 365.

Implementation

• Open Windows PowerShell ISE
• Create a new file
• Copy the code below
• Save the file and run it

• PowerShell
• CLI for Microsoft 365
