Recently I cut-off my house from the public telephone network and wired the whole thing with Vonage on the $14.99/month plan. The voice sounds fine and I was able to get my Series2 DirecTivos to make their daily call over Vonage. The Series 1 units wouldn't do it though, not even when throttled-down to 19.2k. I had to hook them up with TurboNet to make the daily call over ethernet. Overall, I am very happy. $16 (tax inc.) per month for 500 minutes + all calling features is much better than $50+ per month for 0 minutes and caller ID.
