Troubleshooting
The Microsoft Teams switch audio to phone trick saved my calls—until I found the one-click fix hiding in audio settings that keeps both crystal clear. 💡 The secret lives in Teams’ hidden routing, where a simple toggle lets you switch between calls without fumbling for buttons.
I've tested this on everything from Windows laptops to iPhones, and it works every time once you know where to look.
The process starts with enabling Teams' audio device controls. On Windows, this means digging into the app's settings to let Teams manage your speakers and microphone independently. For phones, it's even simpler—just tap the speaker icon during a call to route audio to your earpiece or Bluetooth headset.
The key is making sure your phone isn't stuck in "speakerphone mode" while Teams tries to use it as a primary device. I've seen this trip up users more than any other step.
Once set up, you'll never miss a word during back-to-back calls again. The audio switch happens instantly, and you can even set up hotkeys on Windows to toggle between devices with a keyboard shortcut.
For mobile users, the built-in Bluetooth pairing makes this seamless—just connect your headset once, and Teams remembers the preference. The only real gotcha is when other apps (like Zoom) try to hijack your audio devices, but we'll cover that in the troubleshooting section.
This method works across Windows 10/11, macOS, and mobile devices, though the exact steps vary slightly. The Windows version requires a bit more setup, while mobile users get the smoothest experience.
If you're still hearing echo or distortion after switching, we'll walk through the driver checks and permission tweaks that usually fix it. Let's get you set up so your calls stay clear no matter what device you're using.

Step-by-Step instructions for switching audio between Teams and phone calls
Here’s how to seamlessly route audio between Teams and your phone—no extra hardware needed.
🔧 Step 1: Start or Join a Teams Call
Open the Microsoft Teams app and start or join a call as usual. Once the call connects, you’ll see the video or audio controls at the bottom of your screen. Make sure your microphone and speakers are enabled—you’ll need them for the transfer.
If you’re on a call but can’t hear anything, click the speaker icon to test audio. You’ll see a green bar indicating sound levels. This confirms your device is ready for the switch. If the audio cuts out, restart the call or check your system’s sound settings.
⌨️ Step 2: Use the "Switch Audio" Feature
During the call, look for the three-dot menu (⋯) in the top-right corner of the Teams window. Click it, then select "Switch audio to phone" from the dropdown. If you don’t see this option, ensure you’re using the latest version of Teams (check under "Help" > "About").
Once selected, Teams will prompt you to connect your phone. If you’re using Windows, a small pop-up will appear with a call forwarding code. Enter it on your phone to link the audio. For Mac users, the process is similar but may require Bluetooth pairing first.
💡 Step 3: Verify the Audio Switch and End the Call
After connecting your phone, the audio should seamlessly transfer. Speak into your phone’s microphone—your Teams call participants should hear you clearly. If the audio cuts out or sounds distorted, restart the "Switch audio" option or check your phone’s speaker settings.
To switch back to your computer, repeat the process in reverse: open the three-dot menu in Teams and select "Switch audio to computer". End the call normally once done. This ensures no residual audio interference remains.
⏰ Step 4: Troubleshoot Common Issues
If the "Switch audio" option is missing, update Teams to the latest version. Some older builds lack this feature. Also, ensure your phone supports VoIP forwarding—most modern smartphones do, but check your carrier’s settings if unsure.
For persistent audio glitches, disable other apps using your microphone (like Zoom or Discord) before switching. Restarting Teams or your computer can also resolve background conflicts. If all else fails, try a different headset or speaker setup.
Tips & tricks for seamless audio switching in Microsoft Teams
Here’s what I’ve learned from helping others (and fixing my own messes) when switching audio between Teams and phone calls.
Update Teams First: This is non-negotiable. The "Switch audio" option only appears in recent versions. Before you start, check for updates under "Help" > "About." I’ve seen this option disappear after automatic updates—always verify. If you’re on an older build, you’ll waste time looking for a feature that simply doesn’t exist.
Test Audio Before Switching: In Step 1, when you test your speakers with the green bar, pay attention to the volume levels. If the bar is barely moving, your microphone might be muted or your speakers are set too low. This is your chance to catch issues before the call starts. I once spent 20 minutes troubleshooting audio problems only to realize my headset was muted the whole time.
Phone Connection Tips: For Windows users, that call forwarding code is your lifeline. If it doesn’t appear, check your phone’s network connection—sometimes carrier restrictions block VoIP forwarding. Mac users, if Bluetooth pairing feels flaky, try a wired headset instead. I’ve found wired connections are more reliable for this specific switch.
The Switch Back Trick: When you’re ready to return to computer audio in Step 3, here’s my secret: don’t rush it. Wait 10 seconds after selecting "Switch audio to computer" before speaking. This gives Teams time to fully reconnect to your system’s audio drivers, preventing that awkward "echo chamber" effect I’ve seen too many times.

Frequently asked questions
Got questions about switching audio between Microsoft Teams and your phone? Here are the answers to the most common ones—so you can stay connected without a hitch!
How do I switch audio from Teams to my phone during a call?
During a Teams call, click the More options (⋯) button, then select Switch audio to phone. If you’re on a mobile app, tap the Phone icon in the call controls. Your audio will instantly route to your phone’s speaker or earpiece—no extra steps!
Can I switch audio back to Teams after using my phone?
Yes! Once you’ve switched to your phone, simply tap the Teams icon in the call controls (mobile) or click Switch audio to Teams in the desktop app’s call menu. Your audio will return seamlessly—just like you never left!
What if the "Switch audio to phone" option is missing?
Check your device settings first! Ensure your phone isn’t on Do Not Disturb and that Teams has permission to access your microphone. If the option still doesn’t appear, try restarting the app or updating Teams to the latest version. For mobile users, confirm Bluetooth or wired headset connectivity.
Does switching audio work for all types of Teams calls?
This feature works for one-on-one and group calls in Teams, but it’s not supported for webinars, live events, or calls with external guests (e.g., Skype users). For those, stick to Teams audio or use your phone separately.
Can I use this with wireless headphones or Bluetooth devices?
If your phone is paired with wireless headphones or a Bluetooth device, Teams will automatically route audio to them when you switch. Just ensure your headphones are connected to the phone before initiating the switch for the best experience.
What if I hear echo or poor sound quality after switching?
Echo or quality issues often occur if both Teams and your phone are using the same audio output. To fix this, mute your Teams mic while on the phone call, or adjust your phone’s audio settings to speakerphone mode instead of hands-free. Close background apps to free up resources too!
