This is a fairly simple modification that can be made to any phone. All
it does is allow you to take any 2 lines in your house and create a party
line. So far I have not heard of any problems with it from my friends that
have set one up and I have not had any either. There is one thing that you
will notice when you are one of the two people who is called by a person with
this box. The other person will sound a little bit faint. I could overcome
this with some amplifiers but then there wouldn’t be very many of these boxes
made. I think that the convenience of having two people on line at any one
time will make up for the minor volume loss.
