Fake a manual setup?

Looking at this
it should be possible to use it for manual phones, and even let it sound like the original setup.

I just almost removed the dial tone, and the ring back tone.
Now its silent, just a little noise on the line.
How should it ring, yes, only once!  so the ring cadence is changed too, one ring, and loooong pause.

This circuit is primary made for CB telephones without dial, but it works on modified Local battery phones too (capacitors in series with ringer, and receiver). Remember to modify the generator so its not sending current out to the line.
