If you are new to Microsoft Teams or experiencing technical difficulties it is highly recommended that you Make a Test Call BEFORE you "Join" a Teams call. One of the first things you need to do as a new user of Microsoft Teams is make sure your audio and video are working properly on the devices you will be using to connect to meetings and calls.This is a very easy step to complete and if you do experience any problems during the test call they can be addressed before the "real" event. You can make a test call at anytime for peace of mind that your equipment is working properly. The Make a Test Call feature works only in the PC and Mac Teams desktop client, it does not work if using Teams within a browser.
To make a test call, select your profile picture at the top of Microsoft Teams,
then Settings > Devices.
Choose Make a test call under Audio devices.
In a test call, you'll see how your mic, speaker, and camera are working. Follow the instructions from Test Call Bot and record a short message. The message will play back for you. After that, you'll get a summary of the test call, and you can go to your device settings to make changes.
The test call feature is only available in English for now. Additional languages are coming soon.
We'll delete your test recording immediately after the call. It won't be retained or used by Microsoft.
To select the mic, speaker, and camera you want Teams to use for calls and meetings, click your profile picture at the top of Teams, then Settings > Devices.
Under Audio devices, pick the speaker and mic you want Teams to use by default.
Under Camera, select the camera you want Teams to use, and see a preview of that camera's video.
If you have multiple certified devices connected to your computer, you can set one as your secondary ringer, which means it'll ring when a call comes in. Answer incoming calls on any device—not just the ones that ring.
