I have a Sprint tab and got voice calling working on it. NetTalk is the name of the app and its in the market and best of all, its free. you have to sign up for it which i did over my phone. the quality is ok but i havent really made any calls longer than to see if it works. it shows up on caller ID as unknown or private id. i havent messed with it enough to figure out how to make a call to my tab. it has all my contacts in it just like it would on an android phone. the program is in beta from what ive read so i dont know when/if they will start charging for it.
