    Hello, BT activated the master socket in my new apartment but all the extension sockets do not work. Alas, i'm not too familiar with how phone wiring works. Took a look through the internet and found some guides but the colour of my wires does not match those of the guides. Here is the set up I have:

    So a green wire going to 5, blue going to 2 and an orange one going to 3. My understanding is that it is only 2 and 5 that matter. I got an IDC Insertion Tool so i'm rearing to go but I'm not quite sure what to do from here. Here is how the sides look:

    Any ideas? Feel free to explain to me as if talking to a complete wiring newbie

    That's not a master socket

    Irrespective of the wire colours, connect 2 3 and 5 at the extension to 2 3 and 5 at the rear of the removable faceplate at the Linebox.

    Has an orange wire punched into terminal two and not in terminal three.

    That cable is not CW1308 internal telephone cable, It looks like it is stranded ( several copper strands per wire ) and not solid ( one strand per wire ). If it is stranded it cannot be used in punch down terminals.

    The strands move into a flat arrangement as they are punched into the connector and the jaws do not cut through the insulation and no contact is made to the copper. Sometimes there is an initial connection but these are very unreliable and almost all fail, minutes or days later.

    That is the new cable used by Openreach (they call it cable equipment 2502)
    It is exactly the same as cw1308 and is solid not stranded conductors.
    This colour code that BT stopped using late 70's, is now used again but only on the 2 pair cable.

    So as OwainDIYer mentioned, that was not the master socket just the extension. Here is how the lower plate looks on the master socket:

    Yup...there are no cables hooked up to any of the numbers. When I take a look at the top part I see the blue and orange connected to A and B while Green and Brown are just dangling by themselves:

    So is the solution just to replace 5 in the extension socket with brown instead of blue and then connect green and brown to the lower plate numbers 2 and 5 respectively in the master socket?

    You connect terminals 5 3 and 2 in the extension sockets to terminals 5 3 and 2 on the linebox faceplate as below

    You ignore terminals A and B on the linebox rear part which is for BT Openreach use only. You must connect your extensions to the removable front plate.
