Hello Tech Community,
We are currently experiencing an issue where users are hearing a dial tone in a Microsoft Teams meeting. We are currently in Islands Mode and the default chat app for Office is Skype for Business, and the users use both applications.
We initially thought that the issue was due to users attempting to use call controls for Teams, therefore taking Skype into an off-hook state , causing that dial tone. However, one of our UC guys has said that this isn't in fact what is happening. When he either clicks the Teams toast or the join button from the calendar, the Teams meeting starts as usual, but Skype plays a dial tone, and he needs to exit the Skype app for the dial tone to stop.
This also seems to have coincided with a recent office application update.
Any help with this would be greatly appreciated.

Hi, Did you identify the cause of this issue, we are experiencing the same problem, usually with the first call of each day. We have a call open with MS for it, but as we cannot systematically recreate the problem troubleshooting is proving difficult.

This is likely being triggered by your headset. Try if you can reproduce this issue with audio-jack headset, not the USB or wireless.
My customer is using Jabra Evolve 65 headsets with Jabra Direct software installed on all Windows 10 client. After disabling "Softphone Integration (Bluetooth)" in Jabra Direct issue is resolved.

This is a known issue when Skype and Teams are simultaneously being used.
For some users that tried to turn off the Dial Tone on Windows it worked.
Try to follow the steps below to check if it will fix the issue:
1. Search Sound in the Windows search box and click to access.
2. Click Sounds tab.
3. Under Program Events, scroll your mouse and select Dial Tone under Skype for Business.
4. Switch the Sounds to None.
5. Click Apply and then OK.

The final solution for this issue in our environment was to change the value on the registry key EnableTeamsHIDInterop for the users in Island Mode via Policy. The value was changed to 1.
