I went back to AAISP to say I'd been told there was only Marconi in my exchange. They said no it isn't so I went back to Plusnet. They eventually managed to get me shifted to the alternative equipment and back on Max Premium - no more disconnects when the phone rang (and the strange gap between the upstream and downstream tones disappeared).
