I just don't see how these things come up with the relatively high v.
and current needed to power an old electro-mechanical bell.  I have a
model 302 and I know it has a capacitor in it, I guess to get things
started, but that 40, or 90 v., whatever it is that's needed to power
an old ringer, I don't see that happening on the internet phones.
