I just tried dialing through one of the access numbers (213 area code), and yes it does connect to the Vonage application on my iPod Touch if the application is open. If it's not open, the connection is just dead air and then cuts off. In fact, dialing 011-883-510-xxxxxxxxx from my Vonage line also connects the same way, and the call doesn't appear in my call history (at least not yet).
