The plug on your existing phone fits the green socket at the rear of the hub.
Where does your phone plug into currently? The standard telephone socket is a 431A the same as the green socket at the rear of the hub. If for some reason your phone has a non-standard RJ11 plug, you can use an RJ11 to 431Adapter.
Thanks for the information, the box i have was a bt broadband one ,it had 2 sockets one for landline one broadband which i cant use any more as its obsolete now that ive got fibre optic .
I really didnt want to get a new phone as ive only had this one a couple of years .
Exactly, the socket for broadband would be Rj11 and for the phone 431A . The phone socket at the rear of the hub is a 431A the same as the phone socket on the 'box'.
I don't understand why your phone has an Rj11 plug.
