Very loud high pitched tone coming out of phone socket

[HannahLucy]

My master socket is now doing this, this is the only online reference I can find to this situation!

The solution was not including on the notes, I’d very much appreciate it if you could now state the solution? I take it a BT engineer was the way forward?

I have a tiny flat it is not a noise I can ignore!

Is this still a problem?
