I have two lines at home, one normally used for a modem. Of
the 4 wires in any jack, red & green hook up the main line and
yellow & black (if connected to red & green on the phone) hook
up the second line.
I'm curious to know whether I can construct something which will
let me achieve conference calling by using both lines -- the
electronic equivalent to holding the mouthpiece of one phone to
the earpiece of another, I guess. In other words, if I'm at home
talking to my wife on one line and our broker on the other, can
I do something which will let them hear each other as well as me?
I realize I can get conference calling from the phone company;
I'm curious as to whether I can do it with what I already have.

some cheap two line phones have this as a feature. (I got mine from some sleazy mail
order house whose name escapes me) the problem with the cheap ones, is that they have
no buffer amp, so engaging the feature costs 6db. This was more featurefull than the
telco conferencing, as that prohibits certain revenue beating combinations. (It is
impossible for you to conference two incoming calls with telco conferencing, as it is
possible to beat tolls with this arrangement)
