Well if it's in an old phreaking tut, here is the best advice in the world... no.. it won't work and don't try it if you don't want to get in trouble.

I have found out that when my phone rings the line is at 50-54 volts and when answer there seems to be 9 or -9v.
so should the same princable apply would i be able to use a rissistor of some kind when constructing a black box

I suggest the Blue Box. It is much better. You can get full instructions on how to build one in the Anarchist's Cookbook.

hey dippy... Anarchists Cookbook is a bunch of [censored].... get used to it
