Have you tried what I suggested in post 23?

By connecting the red wire (B leg of line) to T2, you are connecting the receiver directly (via a couple of coils and a resistor) across the line, so you will indeed hear the dial tone that is present. You are also applying the DC line voltage across the receiver, which is not a good idea as it can cause permanent magnetisation of it if continued for any length of time.
