Set Up a SPA-2000 With Gizmo5 and Google Voice for Free VoIP Service
Recently Gizmo5 added the ability to configure your Google Voice account within the Gizmo5 interface which allows for you to configure any SIP device (soft or hardware) to have free voice. I happened to have a SPA-2000 around so the below describes how to configure a Sipura SPA-2000 using Gizmo5 and a Google Voice account for free voice. For this howto you will need a SPA-2000, a Gizmo5.com account, and a Google Voice account.
