Microsoft Teams Unmute Phone *6: Quick Dial Code for Hands-Free Meetings

When I unmuted my phone using *6 in Microsoft Teams, I saved myself from fumbling with buttons during that critical client call—no more reaching for the screen or ✨. explaining why I went silent.

The trick works best on supported devices, but even then, a few simple steps keep it from failing mid-conversation.

This quick dial code is built into most modern phones running Teams, though older models or certain carriers might need extra setup. I’ve tested it on Android, iPhone, and even a few business-grade devices—just make sure your phone’s speaker is clear and the call isn’t muted through another setting first.

The command itself is foolproof once you know where to tap it.

You’ll end up with seamless hands-free meetings where you can take notes, sip coffee, or even walk around without missing a word. The best part? No extra apps or complicated menus—just dial 6 when prompted, and you’re good to go.

For those who prefer visuals, the UI method works just as fast.

If it doesn’t work the first time, check your phone’s call settings or restart the Teams app. Some calls also let you unmute via voice commands like “Teams, unmute me”—worth trying if the *6 trick feels too technical. Either way, you’ll never struggle with mute buttons again.

How to use the Microsoft Teams 6 Code to Unmute Your Phone

While you're already on a Microsoft Teams call, simply dial the code 6 on your phone's keypad. You don't need to press any other buttons—just the asterisk followed by the number six. This works on both mobile and landline phones connected to Teams.

I always test this before important meetings because some older phone systems might require you to end and redial the call. If your phone beeps or shows a confirmation, the code worked. If nothing happens, try pressing # after the 6—some carriers need that extra step.

After dialing, check the Teams app on your computer or the call screen on your phone to confirm your microphone icon shows as active. It should display a green microphone (not red or gray). If it's still muted, tap the microphone icon in the Teams app to toggle it on manually.

Here's the thing—some headsets or speakerphones might need a separate physical mute button override. If you're using a headset, check if it has its own mute switch that might be overriding the 6 code. In that case, you'll need to press the headset's mute button first.

Before your actual meeting begins, join a test call with someone else to confirm the unmute feature works. Have them listen while you dial 6—you should hear your voice come through clearly without any delay. This step catches any hidden issues before they become problems during important discussions.

If the audio cuts in and out, try moving closer to your phone's speaker or adjusting the volume on your device. Some office environments have poor acoustics that can interfere with the audio signal. You might also need to adjust your Teams audio settings to prioritize the phone audio input over your computer's microphone.

If the 6 code doesn't work, first ensure you're using a phone number that's properly linked to your Microsoft Teams account. Some virtual numbers or VoIP services might not support this feature. Check your Teams admin settings or contact support to verify your phone number is fully configured.

Real talk: Some corporate phone systems block special codes for security reasons. If you're in a large organization, you might need IT approval to use this feature. In that case, ask your IT department if they've enabled the 6 unmute code for your specific phone system.

Tips & tricks for quick hands-free unmuting in Microsoft Teams

This simple code actually works better than you'd think—here's how to make it foolproof every time.

Speed Test First: I always test the 6 code during a quick call with my assistant before important meetings. Dial 6 while on a test call, then ask them to confirm they hear you clearly. This catches any hidden issues with your specific phone system in just 30 seconds—no need to wait until the actual meeting starts.

Headset Override: Here's what nobody tells you—if you're using a headset with a dedicated mute button, that physical mute might be overriding the 6 code. Try pressing the headset's mute button first, then dial 6 again. Some high-end headsets like the Plantronics Voyager have this quirk, and it's not obvious until you test it.

Audio Settings Backup: Before your meeting, double-check your Teams audio settings. Go to your profile picture → Settings → Devices, and make sure "Speaker" is set to your phone's speaker (not your computer's). I've seen people accidentally leave their computer's microphone as the default input, which can cause audio to route incorrectly when using the phone unmute feature.

Carrier-Specific Fix: If 6 doesn't work right away, try adding # at the end—some carriers like Verizon or AT&T require this extra step for special codes to register properly. This is particularly common with older phone systems in corporate environments where you might not have control over the carrier settings.
