Calling into Dumptruck?

I was wondering if anyone knew how, as an Australian, I could call into the DT? Google Voice isn't in Australia, and I know next to nothing about VOIP/internet phone stuff... Any help would be appreciated :)

Well, depending on how much calling to the US is over where you live you could always make a straight international phone call to the US if you have no other means.

A dumb way: You could send someone in the US an email with your voice recording and they could call in and play it.

Skype still exists :)

(I guess you need a balance, I tend to keep a little balance in my Skype, because I occasionally need to call internationally)
