I found a circuit and instructons of type J and it seems there is some different way of making and clearing a call in CB mode.
Also, can you have multiple field telephones on the line (when not using a CB exchange)?

Yes, you may have several telephones on the line.
In CB mode the telephone has a capacitor in series to block DC in on hook mode, and in off hook mode something to carry dc, often a coil.
Moast field telephones use batteries even in cb mode.
