I’ve used several kinds of VOIP over the years, Dialpad, Skype and Net2phone. I found that Skype tended to be the best. But Vonage offers one better service, a service for your home. Not even our Telephone Company offers that yet. It makes it such a convenience for moving house, managing and it’s inexpensive.
So I think that Vonage Forums provides a lot of support, information and reviews for those who use it regularly or those who are new to the service. If you are looking to buy a Vonage Service, you should find this resource really useful as it contains the experience of 33000 people. If you already use Vonage, there are bound to be people who can help you get a lot more out Vonage!
