is that Google Voice allows two GV numbers being forwarded to one gizmo number.
I got a GV number for my parents in the bay area, and one GV for myself (in the countryside of US :). Both are forwarded to the same gizmo #. Now my parents call the local GV number, it will ring my home ATA and my softphone at work, and so does my home GV number. Works like a charm.
A big thank you to fitwxc and everybody else who have provided so much information about setting up voip. It's fun and it saves money. What else could you ask for??
Happy holidays, everyone!
