# Phone Make your phone app’s actions available to Apple Intelligence and Siri by adopting schemas for calling actions. ## Discussion The `.phone` domain defines app schemas that provide a structured representation for common calling actions and content. Apply schemas in the `.phone` domain to make your app’s phone functionality available to Apple Intelligence and Siri. - [`startCall`](/documentation/AppIntents/AppSchema/PhoneIntent/startCall): An intent that starts calls when people say phrases like “Make a call to Bill.” or “Video call Bill and Maria.” > Tip: Xcode generates a template implementation when you type `phone_` and select a schema from the suggestions list. For more information about making your app’s actions available to Apple Intelligence and Siri, see [Apple Intelligence and Siri AI](/documentation/AppIntents/apple-intelligence-and-siri-ai). ## Topics ### Actions [`var startCall: some AppSchemaIntent`](/documentation/AppIntents/AppSchema/PhoneIntent/startCall) An intent schema that starts a call to a person, handle, or named group.
