So I disconnected all phones and took out the plug in extension plug (which goes in the master socket), into which the filter usually goes and then phone and router wire into that. Plugged phone direct to socket - still noisy. Took faceplate off and plugged into test socket - still noisy. Tried two more corded phones - noisy.
Decided to call BT as I was fed up with it. Got through to India as you do. They tested line said it was OK and I was coming across clear. He read out a script stating there would be (I think) £99 charge if it was found fault was within the property. I said I didn't know what else I could do to ascertain where the fault was given I was connected direct to the test socket and three phones tried. Agreed it was likely a line fault, so I booked a visit a few days ahead.
Next day I lifted the phone - dead quiet! By this time I had the router back connected so connected back to test socket, kept switching phones and connecting everything back again and still ok and with far better internet speed (especially so when direct to test socket). So I cancelled the engineer call to monitor for a while. What do you know - a few hours later I lifted phone and it was crackling away again. But here's the thing, internet has remained stable, and in particular, still faster when connected direct to test socket even though line remains noisy. There is still some sort of problem clearly but I wondered if I might benefit from an Iplate, as we also have very old extension wiring into the faceplate. I see broadbandbuyer.co.uk has them for about £3 something +£2 postage. Amazon similar price.
What do you reckon guys?
