# Configure Audio and Video

The Audio & Video settings let you pick which microphone, speaker, camera, and ringing device the Cloud Voice App Web Client uses, and optionally link a supported headset for hands-on call control.

:::caution
- Video features depend on support from your organization's PBX (Private Branch Exchange, the phone system server that hosts your extension).
- The Audio & Video settings are unavailable in these situations:
  - The Web Client is running in CTI (Computer Telephony Integration) mode, where the app controls a separate desk phone instead of handling call audio itself. The Audio & Video page does not appear at all.
  - The Web Client is running through the Cloud Voice App for Google Chrome extension. The page is read-only and shows the message "Media settings are handled by Cloud Voice App for Google".
:::

## Before you begin

- Allow your web browser to access the microphone and camera on your computer.
- Make sure the Cloud Voice App Web Client is running in **Web Client** mode.

## Configure your devices

1. Sign in to the Cloud Voice App Web Client and go to **Preferences > Audio & Video**.

   The browser prompts you for permission to use your microphone.

2. Grant the Web Client access to your microphone and camera.

   a. Select **Allow** to let the Web Client use your microphone.

   ![Browser prompt granting the site permission to use the microphone](/images/pbx/allow-site-use-microphone-ce.png)

   The microphone is now active.

   b. Select **Allow** to let the Web Client use your camera.

   The camera turns on and a live preview of yourself appears on the left side of the page.

   :::note
   If no preview appears, the camera may already be in use by another application. Close it, refresh the page, and try again once the camera is free.

3. On the right side of the page, use the **Camera**, **Microphone**, **Speaker**, and **Ringing Device** drop-down lists to select the device you want for each.

4. If you have a compatible headset, set it up under **Headset Integration** so you can answer, end, and manage calls directly from the headset. For supported models and setup steps, see [Integrate HID-compliant Headsets with Cloud Voice App Web Client](/pbx/web-client-user-guide/integrate-hid-compliant-headsets-with-cloud-voice-app-web-client/) or, for earlier app versions, [Integrate Headsets with Cloud Voice App Web Client](/pbx/web-client-user-guide/integrate-headsets-with-cloud-voice-app-web-client/).

5. Select **Save**.
