This is a bit confusing. It sounds like the usual master socket has only one socket on the faceplate. If you want to plug in the router, and that socket it OK for the router, where do you plug in a phone?
Alternatively, is it possible to request a faceplate like Sunray's picture above, which has both a phone socket and a modem socket?
On the other hand, if there is an unfiltered socket behind the faceplate, which is usable for the router or my own extension cable to the router, is it permitted for me to take off the faceplate and plug in a cable to extend further away in the house? Will Openreach complain? (Obviously not if I don't tell them!)
