I was looking around for pin out information with little success so I though posting some photos may help others.
As I did not want several connectors and coils of cable to connect my phone line to the Tel1 port on the HUB I purchased a standard RJ11 Lead (only needed 1/2 of it so did not matter what type.
You may need to substitute your colours with the cable positions of mine as many people will have different colour cables.
Pin 1 Black
Pin 2 Red
Pin 3 Green
Pin 4 Yellow
Only Pin 2 and 3 are required.
2 - Blue
5 - White / Blue
Notice numbers are 5 3 2
Connected :
Extension 2 - Blue - Red - RJ11 2
Extension 5 - White/Blue - Green RJ11 3
Regardless of cable colours as mine may well be different to yours :
Extension 2 - RJ11 2
Extension 5 - RJ11 3
So now I have my main phone working on its extension with a RJ11 'flying lead' from the back of the master socket to the Hub 3.
Plugging a phone into the master socket I get a dial tone for a temporary random phone number that BT has assigned (found with 17070), plugging into my extension (from the Hub 3) I get my number that was transferred to virgin media.

The above is a useful reference for anyone with the tech skills for a bit of DIY telephony.
By way of a minor correction for clarity, the RJ11 is 6P4C = 6 Position 4 Conductor. The first and last pins (1 and 6) are unused so the centre two pins in use are actually pins 3 and 4
This link seems to be the most consistent info I have found on the subject of pin numbers

Your info as shown makes sense but may cause some confusion if your RJ11 pin numbers are compared with other reference sources.

Forgot about that, got carried away with the 4 cores rather than including the 1 and 6 position blanks. Rather than try to post and edit I will leave as is now because I think its clear enough. Probably find most people will count the RJ11 at 1 to 4, as the 'real' 1 and 6 are hard to notice.
Guess this would be more accurate
Pin 1 Blank
Pin 2 - Core 1 Black
Pin 3 - Core 2 Red
Pin 4 - Core 3 Green
Pin 5 - Core 4 Yellow
Pin 6 - Blank
Only Cores 2 and 3 are required. (Pins 3 and 4) (Centre Pair)
