The reason for the question was simply that the customer desired some
called an "AOR" or Area of refuge - I think it was. Basically a call
button, microphone and speaker to hear back
with the kicker being "a long distance" the solution has to run. RS485 is
like 4000 feet.
There are solutions our there apparently that are not built on asterisk -
so I was just trying to find
a solution that potentially worked with asterisk.
