In the 8x8 Voice for Teams admin portal, one or more Voice for Teams user's Registration status appears with a red dot . When hovering the mouse cursor over the red dot, a Registration Status of Not found is displayed.
In this case, the user will typically not be able to make or receive phone calls using Microsoft Teams.
This issue may occur even though all settings, information, and licenses are correct in Microsoft 365, 8x8 Admin Console, and the Voice for Teams admin portal, and full synchronization has been successfully performed.
Important: This solution generally applies only to Voice for Teams services which have been successfully set up and fully synced.
If all user Registration statuses appear as red / with errors, this could indicate a general configuration issue which may need to be resolved through other troubleshooting methods.
