Microsoft 365 Help Make a voice or video call
Ring a colleague from your phone using Teams.
Before you start
- An internet connection through Wi-Fi or mobile data.
- Teams microphone permission; camera permission for video.
Follow these steps
-
Open Teams and Chat
Tap Chat on the bottom bar. Open the person’s conversation, or tap New message to begin a new one.
-
Find the right colleague
Type the person’s name and select the correct work account. Check the name at the top before placing the call.
-
Choose voice or video
Tap the phone icon for an audio call, or the camera icon for a video call. A call from a group chat may ring the group.
-
Wait for the answer
Let the call ring. If no one answers, end it and send a brief message asking when would be a good time.
-
Adjust the sound
Use the Speaker/audio-output control to choose your phone, loudspeaker or connected headset. Use the phone’s volume buttons while the call is active.
-
Control your microphone and camera
Tap Mic to mute when you are not speaking. Tap Camera to start or stop video. Tap the screen once if the controls have disappeared.
-
Finish the call
Tap the red hang-up button and confirm that you are back in the conversation.
You have finished when…
- You have spoken to the intended colleague.
- The red hang-up control ends your connection.
Helpful tips
- These are internet calls and may use mobile data.
- Calling a normal telephone number needs a separately configured Teams Phone service; ordinary internal Teams calls do not.
Something looks different?
Call immediately fails
Check internet access and try a known internal colleague. External calls may be restricted by organisation settings.
The camera is black
Check camera permission on your mobile device and that another app is not using the camera.
