if you have vonage . can you use dial up to got on the internet?

Answer 1

No. Vonage is dependent on a high speed internet connection, which will carry your voice service as well as your data service.

Answer 2

Sorry, but no. VoIP requires a broadband connection. However, the Gizmo Project for Windows claims it can use either a broadband or dial-up connection to make calls from one computer to another.

"Publisher's Description:
Gizmo Project uses your Internet connection (broadband or dial-up) to make calls to other computers. With the click of a mouse, you’re connected to friends, family, and colleagues anywhere on earth. It’s just that simple. You talk clearly for as long as you want for free.

With inexpensive add-ons like Call In and Call Out, you can talk to any telephone–mobile or landline–on the planet." --gizmo project
