Problem using Gizmo in E61

All E61 owners interested in VoIP should be familiar with this Gizmo setting instruction for E61. I have it set in my E61 for quite sometime but never try to use it waiting for the 3G. Finally I have a chance to try it out yesterday, the 3G signal is full and I go ahead and try to registered.

Nothing happens, it won’t register, my E61 won’t register, try it and try it again, its the same result, what a disappointment.

Maybe my provider do block ports, better check with them before doing more test.
