You need to do some serious reading about how the telephone signal is
carried from CO to your house.  Radio Shack had a good book on that, but
I don't think that's available where you're at.  IN any case, your
assumptions are wrong.

To sum it up, you cannot just connect the telephone jack wires to an
audio input.  If you do, your telephone will quit working, you may be in
for a very, very nasty surprise if a lightning storm comes by, and you
may get charged by the telco if they find that you have caused a major
problem.
