if voltage is the problem, by law, the household phone wiring must be disconnectable from the phone company  Most post 1984 phone boxes have an rj11 connection which may be unplugged.  That would solve the voltage problem.

Most likely, Comcast has been prohibited from accessing the main junction box to cut off the current because it is probably the property of the big bad arch rival phone company, either Verizon, AT&T or some other regional carrier.  The cable companies hate the phone companies and vice versa, andare seldom willing to cooperate with each other for the customers' benefit.
