how to make a telephone work from play house outside to kitchen?

I was once told about a father who was able to set up a direct line from the kitchen to the wendy house. So the child could have a hot line direct to mum.

You can find fm-wireless broadcast intercoms with a push-to-talk system at radioshack or equivelant. For a 'phone' system with handsets, I have no idea, other than new digital phone handsets that have a 'page' feature.

I read the same article in Popular Science/Mechanics/Electronics?, but it was a very old article that relied on two rotary phones and a battery.
