So, I used to use Vonage. They kept raising their already pretty great rates, but eventually it just wasn't for me. So, I jumped ship early last month and think the decision was pretty good. I've been using Google Voice and Gizmo5. My bill over the past month has gone from $25 to about $5. Not a bad decrease. The quality is just as good and I don't miss Vonage. Plus I ported our old number out so I didn't lose our old number. I did have to configure things and Gizmo5 could be easier to set up, but I got it working for now. Now that Google has bought Gizmo5 it should be interesting to see what they do with it.
