Anyway, I tested this Gizmo5 (SIP) to my Google Voice and it worked.
Really?! I was using a non-Gizmo method to test it, but it didn't work. Which ip did you use?
Edit: What do you know? It does work, using Gizmo5 and IP .11. I wonder whether they opened this up again, or whether it's always worked using Gizmo. It did NOT work for me using other accounts, so perhaps it recognizes my Gizmo number.
