# resolveDestinationType(for:with:)

Resolves the destination of the call.

```
optional func resolveDestinationType(for intent: INStartCallIntent, with completion: @escaping @Sendable (INCallDestinationTypeResolutionResult) -> Void)
```

```
optional func resolveDestinationType(for intent: INStartCallIntent) async -> INCallDestinationTypeResolutionResult
```

## Parameters

`intent`

The intent object that contains details about the user’s request. Use this object to get the initial information, if any, provided by the user.

`completion`

The handler block to execute with the resolution. You must execute this handler while implementing this method. This handler has no return value and takes the following parameter:

- resolutionResult: The object that contains the details of your proposed resolution. For a successful resolution, create a resolution result with the requested destination type.

## Discussion

This method verifies that you can initiate the specified call type. Return a successful resolution if you can place the specified call type. If you don’t support the specified call type, return a not required resolution and report the failure in your [`confirm(intent:completion:)`](/documentation/Intents/INStartCallIntentHandling/confirm(intent:completion:)) method.
