Google Voice Call Charges:

Google voice rates are really cheap if you are using for calling outside your country. What I liked most is calling rates for US which is just 0.01 USD from anywhere in the world.
There are no connection fees levied by Google, you just pay for what you talk. Google Voice Rates page also compares the call charges with leading Internet Telephony service ( Skype).
Calls to the U.S. or Canada placed within those countries will continue to be free at least for the rest of 2011. Calls to the U.S. or Canada placed from outside these countries will be charged $0.01per minute (or €0.01, £0.01, C$0.01 per minute). .

Credits can be added to your account to make the voice calls using Google voice.

If you’re a Google Apps user, your domain administrator must have Google Voice and Google Checkout enabled in the administrator control panel in order to be able to use this feature.
