I see a recommendation in another thread that the best way to do this would be to get the naked DSL enabled on the second pair coming to my house, then once that's working get the current number ported to 2talk, effectively ending the service on that pair with the broadband that's currently on there.
I have a self installed master filter, so swapping that to the unused pair on the incoming line shouldn't be a problem.
But is this still the best way to do it and will it work with a new VDSL connection? And what info do I need to give to snap(?) to ensure the VDSL is installed on the unused pair and not the currently in use one? I guess it would also count as a new connection, though I see that's free on a 12+ month contract with snap.
