How do i get my old telephone extensions working following full fibre install

[RBrucek]

I have read there are ways of doing this but I need very clear instructions please

@RBrucek 

You won't find such instructions here because they typically involve messing with the Openreach master socket, and even where this socket is rendered obsolete by an FTTP installation doing so is somewhat dubious because there's a risk of sending current from the ATA in the Hub back into the external PSTN system.

If you were to search for 'Voice Re-Injection' (VRI) then the website of an interestingly independent-minded small ISP should appear which may or may not have information on the topic to be used at your own risk.

It's perhaps also worth noting that there's (at least in theory) an Openreach master socket faceplate specifically intended for VRI isolation: I've no idea if these are actually obtainable.

@RBrucek Sky currently don't support any means of reconnecting your phone sockets. The simplest solution is to invest in a wireless DECT phone with as many handsets as you need.
