I wish there was a way to tag you contacts to let Google Voice know whether the call should go out with GV or VZW.
I have some contacts (Other VZ users) I call directly with my cell number.
I have other contacts (restaurants, businesses, etc.) I call using my GV number.
The problem is I have to make that choice every time I make a phone call. It is a bigger problem when I use my cars bluetooth dialer, because I have to make the call from the car, then take my hands off the steering wheel to click the option on the phone.
Please Google, allows to tag phone numbers to automatically use the outgoing method I want with each phone number.
