Telephone extension

[AnthonyAkinwande]

When I plug a landline phone into the master socket, it works fine but when I plug the same phone into an extension socket in the living room,  it does nothing. (I've tried it with and without an ADSL filter on all sockets, and I've tried multiple phones)

Our house is a new build (2020) and I didn't realise it wasn't working until now. I called BT customer service and it was not BT's responsibility to fix it - I also asked the agent, if Openreach will be the one to fix and he told me as the landlord it's my responsibility.

What should I do?

Extensions are your responsibility. I would first check the master socket and ensure that the extension wiring is there and it should be connected to terminals 2&5 colour of wire to the terminals is immaterial

Internal wiring for extensions etc is your responsibility or if it's a rental property, the landlords if it's covered in your lease. There's also the possibility that a previous tenant paid for the installation in which case, it's your responsibility if you want the extensions to work

I didn't realise that until now. Thanks, Nigel.

Thanks for the suggestion. Interestingly, only one green cable is connected to terminal 5. It looks like there was no telephone extension wiring

Anthony just for extra info the external line ends up on 2 & 5.  The wiring to the extn socket is also to 2 & 5, if you want the extn to ring, wire connection 3 in both sockets.

Wrong.

There is absolutely no need to connect anything to terminal 3 unless you have an ancient GPO phone.
