After having Google voice for years, I'm going to try to actually use it. Google Voice has an instruction page that says its possible to use their voice system instead of Metro's. Not that I have any particular complaint with the metro VM, but I want to see how it would work. The google page says to dial *74(my ten digit Ph#) like a normal call. But the weird thing is the phone sometimes responds with a verizion message and other times with a message that the call cannot be completed as dialed. Any one know what this means?
