YES! Assuming you are talking about phone lines.
Let me explain why twisted pair is good for data.
When current travels down a wire, it generates a magnetic field. If that wire is parallel to another wire, then current can be induced onto that other wire. Case in point, you hear people talking about 'ghost voltages' on house wiring that is not hooked up. Those wires are having voltage induced on them from parallel runs of active wires.
A twisted pair wire is much less susceptible to induced voltage because the wires cross each other at/or about 90 degrees. In other words, if a phone line is running parallel to an AC line, it will have voltage induced on it. But, if that phone line is twisted wire, the 90 deg twist cancel outs the induced voltage.
With all that said....
If you want to run one or more phone lines to the 'main office', use Cat 5/6 Ethernet cable. It works just as well if not better than the old phone line stuff.
