Thanks for this post. I've been wondering/thinking the same thing. Gizmo has this 'all calls free' activation process that involves inviting others and using the product, etc, and I've done both of those, but somehow one or the other account gets labeled 'inactive' and then no ring. I also have not been able to verify this, but it looks like they want us to buy something in order to make it work.

The other thought is that the no ring problem on Gizmo has something to do with router settings, and this is way outta my league. I have a simple little wireless router (netgear) at home, but I've never tinkered with the settings. Any other ideas?
