I know this question has been floating around all over the internet but I need an updated plan. I have tried so many different ways. Got my sipdroid and my sipgate only to find out Gizmo5 and sipsorcery are both blocked to new users. I am currently working on a boat and I only get wifi out at sea and would love to find a way to make calls. When i try using my google voice I get a message saying "not registered". Dont know what that means. Does anyone know a current way to accomplish this? Thanks.
