I doubt that will work quite like you are thinking.  There is more to an 
analog phone line than the audio that comes over it.  Namely the loop 
current and voltage are also additional bits of signaling.

I don't think there is such a thing as a cross over phone line.

You will quite likely need something like an old school PBX that 
provides analog ports to pull this off.

My other email (which still hasn't shown up to the list) went into more 
details.  TL;DR:  I think an old school AT&T / Lucent / Avaya 'Partner' 
phone system would be a good candidate as they provide analog ports and 
had relatively simple dialing plan.  I've picked them up from swap meets 
/ ham fests for ~$20.

As far as I know, ISDN is similarly difficult to emulate.  You really 
need an ISDN switch to do it.  :-(

It's part of the fun.  Learning and overcoming problems.  It really 
makes you appreciate where we are now, compared to where we have been.
