Wow i tried this and when i dial (poke one of my address book contacts)from my grandcentral account it dials the gizmo number then rings my cell phone only once, it shows on my cell caller id that th call is from my grandcentral number, but does not connect after only ringing once. When i dial directly from my n810 'new internet call' program it will place the call and shows my gizmo number as the incoming call, however i can only hear from the receiving side and i cannot hear anything on the n810 dialing side. i reproduced this peculiar behavior it over my bluetooth in case it was a router issue--any ideas? thanks
