Again - all help appreciated.

Using all the tips above I have now worked out that brown to 2 in the socket with red to 5 gives me a dialling tone. A definite step forward.

I now need to work out how to get the ringer working. Any suggestions? Am I likely to need both remaining wires (yellow and blue). Any suggestions as to which to try and to which connection 3/4. I can’t jump / hold / connect any wires other than two.

Many thanks. Keen to get this functional if possible as it’s a nice designer phone which is perfect for the planned position.

Thanks again,
