RJ11 sockets - use wiring for anything else?

[topt]

The house I am in has about 5/6 RJ11 sockets wired up presumably as originally had a land line.

I think I know the answer but thought I would pose it anyhow. Can I use the wiring for anything else useful - I won't be getting a land line  ?

 

 

There are 4 wires connected.

DC accent lights? Beyond that, not very useful today if they only ran two pairs.  (My house had 4-pair Cat5e wired to RJ11's which I was lucky enough to be able to convert to RJ45's

Thanks for responding.

Yes that would have been nice but appears not to be the case here unfortunately.

RJ45 connectors are for communication devices. I would keep them just for that
