Microsoft Teams 1:1 PSTN (Public Switched Telephone Network) recording does what it says on the tin!
At the time of testing the recordings are placed in the user’s OneDrive “Recordings” folder as a MP4 file. As I mention in the video below this allows the recording to be easily shared, marked for retention or even be linked to a Power Automate flow.
This feature is is intended to support user initiated On Demand use cases, for Compliance recording Teams provides robust Policy Based Recording functionality.
Check out this 90 second video that shows 1:1 PSTN recording in action:
Note: 1:1 PSTN Recording is not on by default and has to be enabled via the Microsoft Teams PowerShell module. The command I used to enable recording for my demo tenant’s Global calling policy was:
Set-CsTeamsCallingPolicy -Identity Global -AllowCloudRecordingForCalls $True
