As usual you will get lots of different answers, I am happy with this solution, and it solves bothe problems, tinkle and privacy:

You may use a quadrac instead, then you just follow the same chemeatics, but the diac is not needed and may just be a wire.

You need one quadrac in each telephone, but it is so small that you will always get the room you need for it.

For those who use modems or ADSL, this may even reduce the phones reduction of the data speed.
