## Overview

CometChat Calls integrates 1:1 and group audio/video calling into the React UI Kit. Install the Calls SDK and the UI Kit auto-detects it, enabling call components.

<Note>
  Ensure `CometChatUIKit.init(UIKitSettings)` has completed and the user is logged in via `CometChatUIKit.login("UID")`. See [React.js Integration](/ui-kit/react/react-js-integration).
</Note>

## Integration

Install the Calls SDK:

```bash lines theme={null}
npm install @cometchat/calls-sdk-javascript
```

The React UI Kit auto-detects the SDK and activates calling features. [CallButtons](/ui-kit/react/call-buttons) renders in [MessageHeader](/ui-kit/react/message-header).

## Features

### Incoming Call

The [Incoming Call](/ui-kit/react/incoming-call) component displays a call screen when a call is received, showing caller info with accept/reject options.

### Outgoing Call

The [Outgoing Call](/ui-kit/react/outgoing-call) component displays an outgoing call screen with recipient info and call status. Transitions to the ongoing call screen when the receiver accepts.
