I guess I must have missed something. I've installed this program, and while it does work, it doesn't work the way I expected, as a phone. Instead, I get the dialer, which in turn calls my cell phone and places the call using the cell phone.

This is ok, but the way I've got it configured, it doesn't use the N810 as the actual phone, just a graphical interface for using GC with my cell.

Now, I have a Gizmo number but I am not sure how or if the Gizmo number is actually needed to use the tablet as the phone.

Can you please tell me how you have the dialer configured?
