To my understanding, it doesn't implement calling functionality -- you have to have a number for the Voice service to call to. It isn't a VOIP client like Skype, so I wouldn't expect this to support the iPod touch any time soon -- unless you were planning on using it to forward to a Skype number or something like that. It's really more of a telephony abstraction than a client.
