I have added this new post to your original thread, as it was still unsolved.
It could be a faulty faceplate.
If its one of these.
Then unscrew the bottom section and plug the phone into the socket behind. See if you get dial tone there. You may lose broadband when you do that, but it will prove whether that faceplate is faulty.
If you do get dial tone, then that faceplate is faulty. To allow things to work, plug one of the microfilters that came with the home hub, into that hidden socket. Then plug both the phone, and the lead from the home hub, into that microfilter, and both should work.
If the faceplate is faulty, then there is a suitable replacement available.
Brilliant, that is deffo the issue, sorted cheers mate! Will BT send me a new one?
You can fit one of these instead, they are more reliable, and have fewer components to go wrong.
In case you get stuck.
You just remove all of the existing facepate by unscrewing the two screws. That will reveal the main test socket as part of the backplate. The Lindy unit plugs into the test socket, and is secured by two screws or self tapping screws (both are included).
The Openreach version has a large number of components which tend to fail, with the symptoms you describe, usually if there is a line surge or storm.
