Using Mattermost voice chat

  • Problem with hearing the call or making yourself heard? 
    • Click the three dots icon, second along in the call controls box in the bottom-left-hand corner, where you can change your speaker output and microphone input.
  • To mute yourself during a call, click the green microphone button, the rightmost button on your call control panel in the bottom left-hand corner (labelled Click to mute when you hover over it).
  • Voice chat on Mattermost feels a little different to Zoom to use. From our initial test for the first version of this training guide – Mattermost voice chat seems to have as its central design feature only allowing one person to speak at a time. So please let whomever is speaking finish, before you try to come in.

Share your screen during a Mattermost call

  • Click the screen icon, the fourth icon along in the call controls box at the bottom left-hand corner of the window (captioned Start presenting when you hover over it).
  • In the pop-up window that appears:
    • Select which window you want to share.
    • Click the blue Share button to start sharing.
    • To stop sharing, click the red Stop sharing button that will have appeared above the call controls box in the bottom left-hand corner of the window.
