Is there a way to play a wav file over an open telephone line? Can
the earphone output of a sound card be used? Would it need to be
amplified or attenuated? Capacitance coupled?

A 600-600 ohm transformer is the usual way. The headphone level is a
pretty good match, but if you pump too much signal into the phone line,
you will piss-off the phone company.

You should post this at s.e.b.
It's fairly simple to do, and the sound card probably has high enough output
for the job.
