Real-time voice or video communication between users on mobile devices or computers
Hi there,
I'm Cherrelyn and I'm here to help.
I'm sorry to tell but the consumer version of Teams doesn’t have the “Test Call” feature built in like the work/school edition. If you want to check your mic, camera, and audio, the closest workaround is starting a call with yourself by creating a private meeting in your calendar and joining from another device or account. You could also make a quick test call to a friend or family member just to check your setup before any important meeting.
I hope this will help and If you have any question please feel free to ask.
Warm regards,
Cherrelyn
