Talktalk doesn't sell the phone service without broadband bundled in and, the way things are going, it's actually becoming more a case of predominantly fibre [fibre to the premises, so Full Fibre] and the landline number may be kept if you order it at the same time, but it's no longer going to function from the traditional Openreach master socket.
It works with the router, using VOIP.
Not an easy transition for many of us!
In the interim Fibre to the cabinet is usually still available, @AdeleA1, and the copper line is still going to work for the landline until Full Fibre is installed.
