I was not aware of the change to "unidentified'.
I am in Canada, but when I went to the US, this year, I got a legitimate GV number. I don't see a way of migrating that to the device as its main, default GV number. The Google service through Obihai seems to be different, maybe a special arrangement by making it dialout-only, to get it back on the device.
Is this info in some sort of FAQ, because I haven't found it on the site yet?
