An error indicating that the notification service extension is missing the required filtering entitlement.

```
static var missingNotificationFilteringEntitlement: CXErrorCodeNotificationServiceExtensionError.Code { get }
```

## Discussion

To call the [`reportNewIncomingVoIPPushPayload(_:completion:)`](/documentation/CallKit/CXProvider/reportNewIncomingVoIPPushPayload(_:completion:)) method, a notification service extension must have a `com.apple.developer.usernotifications.filtering` entitlement. To apply for this entitlement, see <https://developer.apple.com/contact/request/notification-service>.

After you receive permission to use the entitlement, add <doc://com.apple.documentation/documentation/BundleResources/Entitlements/com.apple.developer.usernotifications.filtering> to the entitlements file for the Notification Service Extension target.
