So the nice Telewest man came out, did something outside and now my phone works.
He also checked the digibox (TV) and my cable modem. Good idea that, I’d have hated it if he’d buggered them up whilst fixing the phone.
However he did something to the cable modem, not sure exactly what, something to do with the incoming voltage I think (“attenuated it”) so I’m off to figure out what he did… better not affect my connection speed.
Ohh and whilst I remember, thanks to Brian and Richard for their previous comments. It’s always good to know that there are people out there who know more about things than I do… ehhh… I think that’s a good thing…
