Telephone lines suffer from corrosion, unfortunately copper cable and connectors suffer from damp, this was reported to BT as a noisy line, according to BT the line was testing OK!!! No it wasn’t BT!
Telephone Engineers Norwich replaced the master socket, and while checking all the other telephone points around the house, and there were several, two of them had been installed by a local reputable building firm, who used alarm cable.
Telephone Engineer Norwich can help with all telephone wiring and additional telephone points for Sky or extra extensions.
