# Call Features

> Add CometChat Angular UI Kit call features for voice and video calls, call logs, ongoing calls, incoming calls, and call buttons.

## Overview

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

<Note>
  Ensure `CometChatUIKit.init()` has completed and the user is logged in before using call features.
</Note>

## Integration

Install the Calls SDK:

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

Then enable calling in your `UIKitSettingsBuilder`:

```typescript theme={null}
const settings = new UIKitSettingsBuilder()
  .setAppId('APP_ID')
  .setRegion('REGION')
  .setAuthKey('AUTH_KEY')
  .setCallingEnabled(true)
  .build();
```

<Warning>
  Both steps are required. Installing the Calls SDK alone is not enough — you must also call `.setCallingEnabled(true)` on the builder. Without it, call buttons remain hidden and the Calls SDK is not initialized.
</Warning>

When enabled, [cometchat-call-buttons](/ui-kit/angular/components/cometchat-call-buttons) renders in [cometchat-message-header](/ui-kit/angular/components/cometchat-message-header) and the trailing call button appears in [cometchat-call-logs](/ui-kit/angular/components/cometchat-call-logs).

### Custom Call App Settings

By default the UIKit builds `CallAppSettings` from your `appId` and `region`. If you need custom configuration (e.g. a different region for the Calls SDK or additional settings), pass your own `CallAppSettings`:

```typescript theme={null}
import { CometChatUIKitCalls } from '@cometchat/calls-sdk-javascript';

const callAppSettings = new CometChatUIKitCalls.CallAppSettingsBuilder()
  .setAppId('APP_ID')
  .setRegion('REGION')
  .build();

const settings = new UIKitSettingsBuilder()
  .setAppId('APP_ID')
  .setRegion('REGION')
  .setAuthKey('AUTH_KEY')
  .setCallingEnabled(true)
  .setCallAppSettings(callAppSettings)
  .build();
```

<Info>
  `setCallAppSettings` is optional. When omitted, the UIKit automatically creates settings from the `appId` and `region` you already provided.

## Features

### Incoming Call

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

### Outgoing Call

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

### Call Logs

The [cometchat-call-logs](/ui-kit/angular/components/cometchat-call-logs) component displays call history — caller, time, and duration.
