Redtail has the definitive test. All you need is a 48 volt DC power supply with one lead to your buttset and the other lead to one of the pairs and the person on the other end with their buttset clipped on the wires and the returning pair to the power supply.
The Tellabs 8001 24/48 VDC power supply (I can loan you one if you pay the shipping) is a couple amps and if you can't do it with that in 48 VDC mode, then the talk path over 30 miles is a pretty much hopeless cause.
Of course, you could just get four charged car batteries and skip the Tellabs. DC drops off a lot more than AC over distance, which is why we have AC power lines.
