Sound and voice calls

Open Session tools in the toolbar and switch on Sound to hear what the other computer is playing.

• If the browser holds the sound back, the viewer shows "Click to enable sound": click once.
• If sound is switched off for the session on the other computer, you are told so and it stays off.

1. Open Session tools and press Start call under Voice call.
2. Allow the microphone when your browser asks.
3. The person at the other computer is asked first. The call starts only after they agree.
4. Use Mute and Unmute while you talk, and End call when you are done.

• Your microphone is used only during the call.
• On the other computer, the microphone is on until the call or the session ends, and the session panel there shows that it is on.
• If the person there does not accept, or no microphone is found on your device, the viewer says which.

Chat in the toolbar is a text chat between the two sides, inside the session. What you write is shown to the person at the other device. They can switch chat off for a session.

Sound and voice calls are offered only when the other device supports them and allows them. A phone that is being helped offers neither. A team's policy can lock either one off on its computers.
