I dont have a dial tone, yet when i ring the land line from a mobile, there is a ringing tone on my mobile. I have used a spare phone, in case of power cuts, and there isn't a dial tone on that one either. I live in Gloucestershire.
Sorry to hear of the issues that you're having with your landline barm20.
Are you still having the issue with your phone line, I have located your account and can see that the local fault has been resolved. Please can you confirm is your line is ok now?
