Jangl -- anonymous calling both ways

You never have to find out their real phone number; they never have to find out yours. You just need an e-mail address. You will provide your real number to forward the call to your phone, but no one will see it. Call Me feature for sites and Facebook available.

through a voicemail delivered by email, you and anyone you want to talk with, can be connected very quickly, via local phone numbers, even if your mobile phone isn’t allowed to dial International numbers.

Free while in beta. Eventually, will charge for long distance, or so I read somewhere.
