Is there an Android landline phone?

[Quartz]

I'm looking for a landline phone that will sync its address book with Google Contacts and make them easily available. I'm sure there will be other useful features but that's the big one. Google throws up all sorts of stuff on AliExpress/Alibaba but few over here. And it's got to be a landline phone, not just look like one.

Any particular reason why it has to be landline? I'm not sure it's a good idea since Openreach has already migrated some areas away from copper, meaning VOIP is the better solution.

In my case it's because I get intermittently poor mobile signal. In another case it's because the person doesn't have a mobile and is too old to switch.
