# INStartCallIntentHandling

An interface that handles requests to start audio and video calls.

## Declaration

```swift
protocol INStartCallIntentHandling : NSObjectProtocol
```

## Mentioned in

Dispatching intents to handlers

## Overview

Overview Use the methods of the INStartCallIntentHandling protocol to resolve, confirm, and handle requests to start an audio or video call with the designated users. Adopt this protocol in an object of your Intents extension that’s capable of validating the call information. Your Intents extension shouldn’t try to initiate the call directly. Instead, a successful response involves asking Siri to launch your app to begin the call. Siri delivers an INStartCallIntent object to your handler when the user asks to initiate a call using your app. The provided intent object contains information about who the user wants to call. Use the methods of this protocol to resolve the list of callable contacts and to validate that your app can place the call successfully.
