Are you using Microsoft Teams on a mobile device or a computer?

==> Microsoft Teams on a mobile device

What device and operating system are you using (for example, iOS, Android, or Windows)?

==> Android

Does the issue occur every time, or only occasionally?

==> Some times

From the fail logs, we could see Teams intiating audio routing to speaker instead of BT.

Hi Ravi Chandra Kanithi,

Thank you for providing more information.

Please try the steps below:

Update Android OS and Microsoft Teams to the latest versions

Test with connecting the Bluetooth first before joining the call

If the issue persists, reconnect the car Bluetooth device (remove and pair again)

Is the issue occurring with other calling apps?

Please let me know the results.

Hi,

Please find my answers inline and reply back.

Update Android OS and Microsoft Teams to the latest versions [A] We have already tried but issue still seen.

Test with connecting the Bluetooth first before joining the call [A] This will work, but our use case is during teams call we need to enter into Car and switch ON, this case failing.

If the issue persists, reconnect the car Bluetooth device (remove and pair again) [A] Yes.

Is the issue occurring with other calling apps? [A] No, we checked with Google calling App, we do not see the issue, issue with only Team app.

Please provide solution for it.

Hi Ravi Chandra Kanithi,

Thank you for the detailed information and the logs provided. Based on the behavior described, the Bluetooth connection is established correctly at the Android system level, but Microsoft Teams is routing the audio to the phone speaker instead of the Bluetooth device during the call.

As this appears to require deeper investigation from the product team and is outside the scope of support available through the Microsoft Q&A forum, I strongly recommend creating a support ticket with Microsoft. This will allow the engineering team to review the logs and investigate the issue further.

Please contact your Microsoft 365 administrator and have them open a support request through the below:

Go to the admin center

On the bottom right side of the page, select Help & support.

I appreciate your understanding.

Dear Ravi Chandra Kanithi,

Thank you for posting your question on the Microsoft Q&A forum.

Based on your description, it appears that when you are in a call on Microsoft Teams and then start your car, the audio sometimes does not transfer to the car’s Bluetooth system.

Could you please confirm the following information so we can further assist you:

Are you using Microsoft Teams on a mobile device or a computer?
What device and operating system are you using (for example, iOS, Android, or Windows)?
Does the issue occur every time, or only occasionally?

In the meantime, you may try manually switching the audio device during the call by selecting More (…) > Device settings, and then choosing your car’s Bluetooth device as the speaker.

You can also refer to the link below:

I look forward to hearing back from you.
