Admin impact, Feature update
Updated October 09, 2020: To ensure the best possible experience for our users, we are delaying some of our deployments to reduce the amount of change flowing into the services. Please see the updated roll-out timeline below
With MC209349 (April 2020) and MC217648 (July 2020), we added a level of privacy for participants who call in to a Teams meeting via audio conferencing (PSTN) by automatically masking any PSTN participant phone number to users from outside of your organization who might be on the call.
We are now adding an admin control for this feature.
This message is associated with Microsoft 365 Roadmap ID 67091.
When this will happen
We will begin rolling out this out in mid-October (previously early September) and expect the rollout to be complete by mid-November (previously end of October) .How this will affect your organization
There is no direct impact or change on your users; the default setting will continue to mask participant phone numbers only for external users.
With this control, you can disable masking or you can mask phone numbers (PSTN) from all meeting participants (both internal and external).What you need to do to prepare
You will initially be able to change this setting via a PowerShell cmdlet. We will update this post with those details when they are available.
