I've had an idea for a dock that turns your smartphone into a landline of sorts. Plugs into an actual corded phone base and only rings the physical landline phone.
I remember at some point some novelty shops selling bluetooth and wired phones resembling old school landline phones, those could be a useful starting point for such a design.
