Getting the right handset is crucial to this build. The lucky thing is, the right handset means the right one for YOU. I will explore three different models of handsets, two that will work, and one that will not.

Homemade PBX

It works! From a telephone, it sounds indistinguishable from the real telephone network. When a call to another extension connects through, there is no click, you merely hear the dying oscillations of the bell as the handset is lifted away. Phones and answering machines of every description have been tried with this and all work fine.
