One limitation of the iPhone is that it doesn't support multitasking for third-party apps. Third-party apps shut down when you switch away from them, you can't leave them running in background. Voalte solves that problem by locating the application intelligence on the server, which sends out alerts using the iPhone's built-in push notification service. When the recipient clicks the button to view the notification, it calls up the local app.
