Video calls and messengers

In short: With messengers and video-call programs you write and speak over the internet. You need a camera, microphone, speakers and a stable connection.

In more detail: Services such as Signal, WhatsApp, Teams or Zoom use the internet instead of a phone line. For video conferences you usually get a link and join through it.

In Depth

• Before the call: Test camera and microphone, headphones prevent echo.
• Muting: Microphone off when you are not speaking.
• Background: Hide an untidy room with blur or a virtual background.
• Share screen: Shows others your window. Close private windows first.
• Privacy: Prefer messengers with end-to-end encryption. Only open invitation links from people you know.
• Problems: Restart the router, pause other downloads, update the browser.
