.Freephoneline doesn't offer free calling to the U.S. Many people on RFD with Google Voice numbers just use Google Voice instead for U.S. calling with Obihai ATAs (2xx series has been discontinued) or IP Phones.

You can buy them in Canada from Amazon or from Newegg - some local VOIP providers also offer it for sale, though I don't know whether those are locked to their respective providers.
Of course just because they stop selling and supporting the ATA doesn't mean that Google Voice is going anywhere and I've done a cursory search and find nothing anywhere from Google that suggests that they would be terminating the service. I use GV for US calling from my home phone system and I have Textnow's app on my phone and can use it from a browser if necessary.
Then there's (admittedly poor quality) phone calling available from my Nest devices,
