If you have a Google Voice account, the associated phone number will be used for outbound calls. You can also forward calls from Google Voice to Google Voice & Video Chat.
The included call screening feature even allows Google Voice users to listen to callers as they leave messages.
Currently calls to US numbers are free, while there is a charge for calling internationally which varies depending on the country.
