I put in a phone extension and it works sometimes, i have double checked the wiring etc and everything seems fine
What happens is this
The main phone will ring once or twice then the one on the extension will also start ringing, however somedays it won't ring at all, all phones in the house are cordless.
The phone cable comes in from the street and goes to the main phone, which daisy chains to an unused socket and then to the new extension, the the original jackpoints both have humoungus capacitors in them, the new one doesn't.
What i can't work out is why it works sometimes and not others, there seems o be no rhyme or reason, the phoneline on the extension is just as clear as the main one
