When I was 14 or so, my mom installed one of those "telephone locks" that blocked outgoing calls and only allowed incoming calls, she did this to limit my dial-up internet. I wanted to see if I could bypass it without my mom noticing.

I noticed that the case for the lock could be pried open easily because it was just a plastic cover with 2 tabs. I examined the circuit and saw that if I could bridge the cables around the lock via a toggle switch, I could have an open phone line during the day and then toggle it at night when my mom came home and she wouldn't know. And so I did. I felt like Kevin Mitnick. I remember documenting the process and posting it to hackaday.com

Funny thing was that my dad found out but he didn't tell my mom. He would just go "hey can you make the phone work, I need to make a call". I later found out he was on phone call restrction too.

That's pretty good. With the device is there some sort of emergency way to split the lock in case of emergency? It would be unfortunate to be unable to make outgoing calls if you needed to call 911.
