The current plan is wireless bridge + directional antennae.  That  
wasn't the problem I needed to solve.

This is an industrial environment.  I'm looking for a slightly less  
expensive (and hopefully more robust) device - whether an intercom  
unit + ATA or a magic black box that does everything I want and has a  
power plug and an ethernet jack.  Dedicating a $175 cisco phone to  
this is overkill, IMO.  I had given thought to this, it is a backup  
plan, but again, I'd like to get something perhaps less expensive to  
the function.
