Yeah, we used a Callback thing when we lived in Argentina. It was a lifesaver since there was no Skype, Vonage or any other Voip back then (at least not one that was commonly known). It was a bummer, though, because our friends/family typically wouldn't just pick up the phone and call like they do with Vonage.

Give them a call lordjosh. . .just make sure you skip right over the call center drones at Vonage who first answer your call. You might need to call via Skype if your connection is still really crappy. I gave them my land line number as well and they promised to call me on that if the connection died.
