Default Re: GEC 1000 phone not working properly?

The line polarity sometimes changes upon different call conditions - or used to. It ought make no difference to the telephone. The only way polarity will make a difference is if wires 2 and 5 are reversed with relation to the bell / anti-tinkle wire, i.e: at the socket-side of the master box.

But IF the telephone had a wire touching the chassis within, and IF the chassis happened to be touching earth...
