A VP at the day job just showed me Gorilla Mobile, a service you can use to call internationally for much cheaper from your cell phone or by dialing a toll free number (US-only, I believe).
The model's similar. It's a lot like prepaid card calling, only without the PINs. Instead, it's all number recognition and savings pass-through type stuff. Whatever the case, their costs are reasonable from the US-out. (There's a price listing on the first page).
Connecting people with each other: Lifehack's 51st mission statement point.
