Dial-in, Dial-out. Same line, easy?

[John D. Daleske]

Does anyone know of good ways to use a phone line for both dial-in and
dial-out?  We have two lines and would like to use both for dial-in until
a need arises to dial-out.  I would prefer being able to use either or
both for dial-out.  If this is not feasible, then dedicating one line
would certainly be no worse than our current situation.

	   Two phone lines, one on a Rixon R212A and the other a Hayes 1200.
