Default Re: GPO 232 won't dial.

Thanks for the enlarged image. I now see why I couldn't find the red handset lead - it is hiding beneath the green one!

One thought has occurred to me, which is something that caught me out a while ago. For some reason, the 232 uses red for the "A" leg and white for the "B" leg. Try swapping these over and see whether that cures your problem.
