# provider(_:timedOutPerforming:)

Called when the provider performs the specified action times out.

```
optional func provider(_ provider: CXProvider, timedOutPerforming action: CXAction)
```

## Parameters

`provider`

The telephony provider.

`action`

The action that timed out.

## Discussion

Depending on the action, a timeout may also force the call to end.

An action that has already timed out should not be fulfilled or failed by the provider delegate.
