TWO WAY WIRED ROOM TO ROOM TELEPHONE SYSTEM (PLEASE HELP)
Firstly im not sure if this is in the right part of this forum.
Basically i want to make (or buy) a two way wired phone system and other end needs to ring upon picking up my end. I've searched here and online for something which will do this and i rememebr having a set of these when i were a kid.
Now i have kids of my own i have built a wooden playhouse at the bottom of garden and would like to be able to ring from there to the house with only a pick up of the other end or something equally similar. IS THIS EVEN POSSIBLE!
If anyone can post me details of how to make this or a website from which i can buy it from would be great been searching for weeks.
