team mysterious ringing

I think I might have found the solution to this issue, at least it works for a few colleagues here (in our case).

EDIT (2023/Mar/24): all right, so now I have more experience on this topic, I'll update below here my conclusions.

What's going on (justification, from my experience):

• MS Teams keep playing the ringtone after hangup of the call.
• Similar to when you are playing music or a video and eventually an incoming call comes in, MS Teams stops and then resumes the audio playback of the background music, I have confirmed that MS Teams it's also (mistakenly) stopping his own ringtone and resuming itself after the call: https://answers.microsoft.com/en-us/msteams/forum/all/teams-pauses-videoaudio-playing-in-teh-packground/b36969ac-2596-40b5-83fa-8af648aef4b6
• I have verified this issue was only happening when the remote side hang-up earlier than me and (at least in my case) never ocurring when I hang-up earlier, plus a combination of the wireless headphones reaction speed (i.e. mostly through Bluetooth profiles HFP/A2DP auto-switching which is a slow process and the issue is reproduced most times).

So far there are only workarounds (as far as I collected):

• (a) Always working (at least in my setup): in order to avoid it, I rush to first hang-up the call myself (avoid the remote side firstly hang up).
• (b) Always working (alternative): if it already occurred and you need to stop it, I enter Team's settings > Devices, make a test call to the robot, and hang up first.
• (c) Most times working (let's say 70% of times): to stop it, on your headphones press the button to pause song/hang-up and the tone will stop playing inmediately. Depends if the tone was detected by the windows built-in player, you can check this by pressing on your headphones vol+/vol- and see if you only see the dark volume slider (upper left) or both the volume and media playing controls
• (d) Most times working (alternative): if you dont have that button on your headphones, in your keyboard press the "volume up/down" keys, a black pop-up will appear that will allow you to adjust the volume and pause the reproduction. Again it works only when the built-in player has linked to the playing sound:
• (e) Initially worked (only for a while):
• (e.1). In Windows 10, open the sound configuration with either ONE option:
  • (A) (techie option) Press Control+R and run "mmsys.cpl"
  • (B) (simpler option) In the start menu type search for "mmsys.cpl"
  • (C) (user friendly) left click on the loudspeaker icon near the time on the task bar (bottom right), select open sound settings, and choose the blue link on the right column named Sound Control Panel.
• (e.2). Then select the "communications" tab, select the option "Do nothing" and ensure that Teams gets the setting. I suggest to restart to avoid the reproduction loop (see later). However, no matter if the configuration in Control Panel is just to reduce the volume by 80% (which is the default in Windows), to stop it, or do nothing, it is confirmed that MS-Teams does not follow this setting.
• (f) Initially worked (only for a while): another user mentioned disabling the autoplay feature: https://support.lenovo.com/pl/en/solutions/ht502955
• (g) And for sure, if your wireless headphones have dual connection protocols (such as propietary dongle and Bluetooth), test with the original brand dongle versus avoiding the generic bluetooth (which has aditional considerations out of this scope).

If it worked for you click the button "helpful" (below), so if it generally works, then may be the creator of the thread would mark it as response workaround.

I am having the same issue. Keep hearing the Teams call sound you hear when calling some, but it continuously loops even after the call. You must close out of Teams to make it stop. I am disabling "Play sound for incoming calls and notifications" under Notifications settings to see if that makes a difference. This issue only started when I connected an external Teams certified speaker(Poly Sync 40).

I do notice an "auto-play" that starts before/after/during making calls. Sometimes I can open the volume panel and see that there is a sound playing in Teams and can press the pause button to stop it.

Sometimes when I answer a call a paused YouTube video in Chrome will suddenly start playing.

Similarly, videos start playing in Chrome when I answer a Discord call.

Sometimes a paused Plex video will suddenly resume for no apparent reason.

Maybe this issue has less to do with Teams specifically as it does a general "pause and resume playing my video/audio when getting a call". Is there some feature in the OS that attempts to pause and resume playing something queued? Maybe when the Bluetooth profile switches from rich audio to voice?

I have the same problem (with the continous calling sound playing) occuring while my headphones (Senheiser PHX 550-II) are connected to my laptop and my mobilephone at the same time. I have the MS Teams app installed on both devices. The sound starts playing after I try to call someone and the call was answered. It won't stop playing even after the call was ended. I have to shut down the MS Teams app through the Taskmanager. When my headphones are only connected to one device everything works fine...

I have exactly the same problem with my Bose NC700 UC

Same exact issue for me - keeps ringing after other party picks up, have to force kill teams.exe to stop it. Bose 700 UC. I've taken to making calls on Teams on iPhone, then "joining" my PC to the call for screen, etc.

So frequent I've added a macro to run in always-open admin command line:

taskkill /f /im teams.exe

This is annoying, and it's been an open bug since 2020?

Have exact same thing. Started last week.

1. I have Teams installed only in one device.
2. My headset is a simple plug in ($10-$20)
3. Operation : Windows 10

Last week I was on the call, and I heard this call music but when I finished the call with my colleague, the music was there but there was no notification on who was calling or anything. the sound went on so I had to log off Teams and re-log and afterwards there was no notification that I missed anything.

This morning, I had call music - not that long and stopped after maybe like 10 secs but there is no alert telling me who called or what.

I'm not sure what is going on but I hope this is fixed if I'm getting a ghost call.

Thank you,
