Details:

Microsoft Teams will soon support noise suppression for dial-in participants. This feature automatically filters out background noise (e.g., traffic, typing) for users who join meetings via phone (PSTN). It enhances clarity and reduces distractions for all meeting participants. The feature will be rolled out gradually. However, if you'd like to enable it yourself, you will be able to do so via the Teams Admin Center: 1. Go to Meeting policy 2. Navigate to the Audio & video section 3. Set Noise suppression for dial-in participants to Enabled or programmatically with MicrosoftTeamsPowerShell by setting NoiseSuppressionForDialInParticipants setting inside of CsTeamsMeetingPolicy to "Enabled".

Imagine you're in a busy coffee shop trying to have a conversation with a friend over the phone. There's the sound of espresso machines, people chatting, and cups clinking. It can be quite difficult to focus on what your friend is saying. Now, imagine if you had a special filter that could block out all that background noise, allowing you to hear your friend clearly. This is similar to what Microsoft Teams is introducing with its noise suppression feature for dial-in participants.

In the context of a Teams meeting, participants who join via phone often bring with them the ambient noise of their surroundings, whether it's traffic, typing, or other distractions. This can make it challenging for everyone else in the meeting to concentrate on the discussion. The new noise suppression feature acts like that special filter, automatically reducing unwanted background sounds for those who dial in. This means clearer communication and fewer interruptions during meetings.

For those managing Teams settings, enabling this feature is straightforward. Think of it like adjusting the settings on your car's GPS to avoid toll roads. You simply go into the Teams Admin Center, find the meeting policy settings, and turn on noise suppression for dial-in participants. Alternatively, if you're comfortable with using scripts, you can enable it programmatically using MicrosoftTeamsPowerShell.

This feature will be rolled out gradually, but if you prefer to have it sooner, you can enable it yourself through the admin settings. It's like getting early access to a new tool that makes your daily operations smoother and more efficient. Whether you're in a bustling office or working from home with background noise, this feature aims to enhance the clarity of your meetings, making them more productive and less stressful for everyone involved.
