# CXProviderConfiguration

An encapsulation of the configuration of a provider object.

## Declaration

```swift
class CXProviderConfiguration
```

## Overview

Overview A CXProviderConfiguration object controls the native call UI for incoming and outgoing calls, including a localized name for the provider, the ringtone to play for incoming calls, and the icon to display during calls. A provider configuration can also set the maximum number of call groups and the number of calls in a single call group, determine whether to use emails and phone numbers as handles, and specify whether to support video.
