Starting December 18 2020, Microsoft are changing how 1:1 Call recording is enabled in Teams.
Currently, 1:1 Call recording is controlled by the -CsTeamsMeetingPolicy / AllowCloudRecording attribute. Microsoft are now changing it so that 1:1 Call recording can be controlled by its own policy. This means that after December 18, 1:1 Call recording will be controlled by the -CsTeamsCallingPolicy / allowCloudRecordingForCalls attribute.
By default, this new policy attribute will be set to false, so 1:1 call recording will not work unless you change this attribute to true.
Follow this Wave 9 Guide to enable 1:1 recording.
