The closest thing to a demo for message delivery would be the Outbound example application (In TeleFlow Designer, click File >> New Application >> Example >> Outbound >> OK) . It isn't a "finished" application, as it is more of a template with some explanation of how to successfully build an outbound calling app that pulls numbers to call from a database.
You could use that as a starting point, and build up your application from there. You would need to create a database and a method for populating it with numbers, as well as modifying the application to suit your needs. The example is really only for a single port of callout without some work.
Alternatively, we do have a TeleFlow Dialer product, which is a finished dialer application that would require considerably less effort on your part to run with. For more information on the TeleFlow Dialer, contact
