I have an invite to Waffles.fm. I want and U.S Google Voice account with phone number, calling and texting.

Google Voice accounts are free by the way; anybody an make one.

you want to one from someone else because it's anonymous?
why don't you just go behind a proxy and create one?

sorry if i go off topic, trying to help

You need to link it to a phone number. I do not want my phone number linked to it.
