I've just tested the phone directly into the test socket and there is definite noise on the line in the test socket.

with or without the router ?

I've tried two routers, same issue.

Does sound like a high resistance issue, but at the time where it just affects ADSL, over time they usually get worse.

Ruling out all your own hardware including router and then getting a CIDR (or is it CIDT) test done can sometimes help identify it

Without.

If it was a dry joint the effect can be to pick up lots of RF noise

That's true, it could tend to act as a rectifier. I hadn't thought of that.

I've tried 3 different filters, 2 RJ11 cables and 2 routers. The issue remains on all hardware.

so a voice fault - you can run a diagnostic test from BT.com if it's a BT line (not LLU)

My line is provided by my ISP, Vivaciti. They ran diagnostics on Thursday and Friday which apparently came back all clear.

If its showing up when NO ADSL hardware/filters are connected to the line, then a voice fault to voice line rental people would be the way to go and don't mention ADSL

So I should start a new ticket?
