You won't get shocked from a domestic phone line. At most you'll get a
little tingle if you were holding both legs of the line and someone rang
you at the same time. Normal voltage is just 50v DC, which rises to 70
when ringing.

My only concern is getting a shock or shorting everything out! I plan
to cute the white sheath away very carefully and then to deal with each
wire individually. Can I get a shock in this way?
