I also subscribed to Vonage when I moved a couple of months ago. I also had to choose an area code other than my own. The phone worked for one day....ONE DAY... and then it wouldn't work no matter how many times I tried to reprogram it. I spent hours on the phone with Vonage and my cable service, and both blamed each other. I sent the Vonage thing back and cancelled the service.
Like Davey or someone else here said, if it sounds too good to be true...
