> 📍 **Where to find it:** (during a call) Floating call card → Mute / Hold / Speaker buttons

During a call, a floating card brings together the essential controls: mute your mic, put the caller on hold, and choose/test the speaker.

## How it works

The "Mute" button turns off your microphone on the browser side (the caller no longer hears you, but you still hear them). "Hold" puts the other participant on hold on the server side (they wait, and you can resume whenever you want). The speaker selector lets you route the call's sound to the headset or speakers of your choice, with a "Test sound" button.

## Step by step

1. Once the call is answered, find the row of buttons on the call card.
2. Tap "Mute" to turn off your mic, and again to turn it back on.
3. Tap "Hold" to put the caller on hold, and "Resume" to come back.
4. Tap the speaker icon to choose the output device and click "Test sound" if needed.
5. Hang up with the red button.

## Good to know

- If you only hear the call through a headset, open the speaker selector and choose the right device.
- The speaker selector only appears if your browser can list audio devices.
- The mute button acts on YOUR mic; hold acts on the caller: they are not the same thing.
