CoWork Calls is an extension to allow users of CoWork to actually talk to each other. Every channel gains the option to start a voice call, video call or screen sharing with all other users in the channel.

Channels with an active CoWork Call have an additional speaker phone icon in the channels list.

The call itself is displayed above the chat window. The layout of the calls can be changed into:

• Grid (default)
• Speaking person or selected person, where the list of participants can be hidden
• Full Screen

There is a list of actions that a user can perform while in a call:

• Mute
• Enable / disable video
• Share screen or window (depends on browser capabilities)
• Switch microphone, speaker or camera (activity level is displayed live)

When in a conference call users, users can raise their hand to indicate that they would like to speak up. This features is useful in calls with numerous participants where everybody is usually muted.

Hands raised are displayed on the users video or avatar as well as in the top left corner of the calls area. Additionally a number indicates, how many hands were raised.

Reactions are a likewise feature to express emotions during the call. That could be feedback during a presentation for example. Reactions are somewhat anonymous since they just float over everybody's calls screens - without names attached.

For CoWork Calls to work it is required to set up the server using HTTPS, e.g. via Let's Encrypt. Users have to have a microphone and optionally a camera attached to their computer. The operating system and the browser must be allowed to use these devices. Users are usually prompted for permission by the browser.
