The new GVJackApp is an extension of GVMate from the same company and allows you to turn on any expired (or not expired) magicJack USB dongle via the same tactics that are used with a GVMate device. Just download the GVJackApp and hookup any expired magicJack or magicJack Plus. It comes with a 7-day free trial and costs just $12.95 for the standard version or $19.95 for the professional version (this is a one-time fee and it will never cost you another penny). Go through the normal magicJack installation process. Then download the GVJackApp and follow the steps provided. You can then use the magicJack to make free calls via Google Voice in the same manner that the GVMate uses.
