# Configure Audio and Video Devices

The Cloud Voice App lets you pick exactly which hardware handles your calls, so you can route ringing to your speakers while talking through a headset, or send video from a specific camera. This page walks through selecting those devices in the Desktop Client.

## Before you begin

Run the Cloud Voice App in Desktop Client mode. The device settings below are available only in this mode.

## Choose your devices

1. Sign in to the Cloud Voice App Desktop Client and open **Preferences > Audio & Video**.
2. Under **Multimedia Device**, use the drop-down lists to assign each function to the hardware you want:
   - **Camera**
   - **Microphone**
   - **Speaker**
   - **Ringing Device**

   :::note
   Video calling requires your organization's server to be on the Ultimate Plan (UP). Without it, the **Camera** option is unavailable.
   :::

   :::tip
   The **Ringing Device** is separate from the **Speaker** on purpose. Point ringing at a device you can always hear (such as your computer's built-in speakers) while call audio stays on your headset. That way you still notice incoming calls when the headset is not on your ears.

3. If you use a headset that works with the Cloud Voice App, configure it under **Headset Integration**. This lets you answer, end, and manage calls straight from the headset controls. Support depends on the headset exposing standard HID (Human Interface Device) call buttons, which most business headsets do. For supported models and setup steps, see [Integrate HID-compliant Headsets with the Cloud Voice App Desktop Client](/pbx/desktop-client-user-guide/integrate-hid-compliant-headsets-with-cloud-voice-app-desktop-client/).
