I am also using Google Voice with a Callcentric incoming phone number for caller ID and 911 ($1.50 per month). But my caller ID has been hit and miss for display of the NAME and I don't know why. About 60 to 70% of the time it displays the name and the rest of the time it only shows the phone number. I submitted a ticket to Callcentric, but so far they don't seem to be able to help - I guess I got a rep that does not know enough about tweaking the Obi's settings?
Anyway, if anyone reading this has an idea, I would be appreciative!
