Microsoft Teams Unmute Phone *6: Instant Audio Fix During Calls

I was mid-presentation when my phone muted itself during a Teams call. ✨ That’s when I discovered the 6 shortcut—a lifesaver that restores audio in under a second without fumbling through menus.

It works across all platforms, from Windows desktops to mobile devices. No special permissions or app versions required—just dial 6 on your phone’s keypad during any active Teams call.

This trick has saved me from awkward silences more times than I can count. Whether you’re on a work laptop or your phone, the fix is the same and just as fast.

If it doesn’t work, double-check you’re using the phone’s dial pad, not the Teams app interface. Simple, reliable, and always there when you need it most.

What Youll Need

Instructions

Here’s the procedure I follow to quickly restore audio during a call without fumbling through menus.

First, check the visual indicator in the call window. The microphone icon will have a red slash through it when muted. I’ve seen cases where users thought they were muted but actually had a hardware issue instead—always verify the on-screen status first.

If you’re using a phone dialed into the Teams meeting, look for the mute symbol on your phone’s display. Some conference phones show a solid red light or on-screen mute icon that’s easy to miss during a busy call.

On your phone’s dial pad during an active Teams call, press 6. This is the universal unmute code for Microsoft Teams conference calls. The system will announce “You are now unmuted” or display a confirmation message on supported devices.

Real talk: this works on PSTN dial-in numbers and most VoIP phones connected to Teams. I’ve tested it with Polycom, Yealink, and standard smartphone dialers—it’s consistent across platforms. The code takes effect immediately, so you can start speaking right after pressing it.

After pressing 6, speak into your phone and ask if others can hear you. Watch for the audio level indicator in the Teams call window (the microphone icon should show green bars when you speak).

If 6 doesn’t work, you might be using a different conferencing system. Microsoft Teams uses 6 for unmute, but other platforms use different codes. Confirm you’re in a Teams call by checking the dial-in number format (typically starts with your country code followed by a local number).

Before joining important calls, test your audio setup. Dial into a test Teams meeting and verify that 6 works to toggle mute on and off. I like to do this 5-10 minutes before critical meetings to avoid last-minute issues.

Consider keeping a cheat sheet near your phone with common Teams call codes: 5 for raise hand, 1 for help menu, and *6 for mute toggle. This saves precious seconds when you need to act quickly during a call.

Tips and Common Mistakes

Small details make the difference between a smooth call and a frustrating silence.

Visual Confirmation: In Step 1, don’t just glance at the screen—actively look for that red slash through the microphone icon. I’ve seen too many people assume they’re muted when it’s actually a hardware issue. Conference phones often have subtle indicators like a solid red light that are easy to overlook in a busy call.

Immediate Action: The 6 code in Step 2 works instantly, but timing matters. Press it once and wait for the system confirmation (“You are now unmuted”) before speaking. I’ve tested this on PSTN and VoIP systems alike—it’s reliable, but don’t spam the button or you might accidentally re-mute yourself.
