# handle(intent:completion:) Handles handing off the call to your app. ``` func handle(intent: INStartCallIntent, completion: @escaping @Sendable (INStartCallIntentResponse) -> Void) ``` ``` func handle(intent: INStartCallIntent) async -> INStartCallIntentResponse ``` ## Parameters `intent` The intent object that contains details about the user’s request. The information in this object has already been resolved by the user. `completion` The handler block to execute with your response. You must execute this handler while implementing this method. This handler has no return value and takes the following parameter: - response: The [`INStartAudioCallIntentResponse`](/documentation/Intents/INStartAudioCallIntentResponse) object that contains the status of the request. This parameter must not be `nil`. ## Discussion Use this method to transfer control of the call to your app. Perform any final checks and create a response object with the information needed to initiate the call in your app. Don’t try to initiate the call directly from this method. When your response object contains the [`INStartAudioCallIntentResponseCode.continueInApp`](/documentation/Intents/INStartAudioCallIntentResponseCode/continueInApp) code, Siri automatically launches your app and passes it the object from your response object. --- Copyright © 2026 Apple Inc.
