I have 2 R10's and vonage. A year ago when I got the R10's I had absolutely no problems dialing over vonage to activate them. No filters, no special codes, just plugged them in and they worked right away. Since the activation, neither unit has been plugged into vonage and has not made a call in 343 days. I get the daily nag screen, but that is it. I was told by customer retention when I got the R10's that they would not work unless continuously connected to a phone line. I didn't believe them. I don't have unlimited vonage, so I don't want DirecTV wasting my minutes.
