Default Re: Vintage GPO 1970 Telephone No 746 Pax 68/1

As Russell says. Remove the Broadband filter (and the router) and see if you get Dial Tone. If not, then check continuity of the telephone cord to the socket. If that fails , check for any loose screws and terminations in the telephone, and check for any dry soldered joints.
