I know full well about disconnected ringers on old phones. My dad's house has a phone with a mechanical bell in the basement that does not ring. In all these years, we never opened it up to see if the ringer was disconnected. I'm told (by the daughter of the first owners of my house) that when the bar was put in, in the late 1960s, they had a phone in the bar (which explained the hole in the side wall of the cabinet), and its ringer was disconnected so the phone company wouldn't "know". That phone, or any phone for that matter, was not present when I moved in. I never knew about this starter/neon trick. However, it likely explains how that phone I have with the red neon "message waiting" indicator light might work. I haven't any idea how they made them light up solid when they were used in hotels back in the 70s and 80s. On the phone I have, the indicator lights when there is ringing current on the line. The bell in it is bad though.

I looked up those Neon "message waiting" lights. The PBX/Hotel switchboard would send a 85-140 volt DC signal (AC is required to make the phone ring although you might hear a mechanical bell go "ding" briefly when received) to illuminate those.

Pretty interesting to know that the voltage used for landline phone signals is similar to that of Japan's domestic voltage.
