This gadget is a replacement for those $20 boxes you can buy at Radio Shack that automatically dial *67 every time you pick up the phone. Considering that you have to dedicate a voice note taker to this task and that those things cost almost as much as the $20 box mentioned above, and considering that this box doesn't work as well, and considering that in most places permanent Caller ID blocking is available and free, one has to wonder what the point would be of building this thing.


The textfile author doesn't explain how to stop the thing from annoying incoming callers with the *67 tones every time you answer.

Plausibility

Semi-workable but not economically feasible for what it does.

Obsolescence

Will last as long as *67 does.

Skill

Some electronics skills required.

Risks

None, it's legal.
