This is not definitive just based on my experience, but I have been using Google talk, Gmail voice and video chat, and the Google voice service daily for a couple of years. The only associated costs I have seen are.
there aren't hidden costs, but the 'free' price tag will not sustain much. and remember always, even if you do get the calls for free, no one guarentees your calls are not called and later on initialised for whatever data they want to dig after.
Google has powerful algorythems and methods to build profiles for people and the day is not long before they will rely on voice over IP as well. you can read in their pricing page (link: https://www.google.com/voice/rates )
good luck. and remember, big brother is always watching.
