This article explains how to record a call with Google Voice, how to retrieve recorded calls from Google's servers, and what the privacy implications are.

You can record your calls on your computer, smartphone or any other portable device. Google Voice can ring multiple phones when receiving a call, so the option is available on all devices. Since the recording mechanism is server-based, you don’t need anything else in terms of hardware or software.

Google doesn't enable call recording by default to prevent people using touchscreen devices from accidentally recording a call without realizing it. (Yes, it's that simple.) For this reason, you have to enable call recording before you can use it.
