The BTOR chap came and guess what QLT perfect not any noise etc. when he tested the line
used his Jedec tester all within spec.
After an hour he went , So I did a QLT and yes crackle pop click yes the noise was back.
He told me there were 3 joints from my house to the pcp at 381M away.
Tonight a friend of my wife called and she said she had been trying to ring for about 2 hours, she said to her it was ringing but it did not ring for us.
Looks like got to phone the BT 0800 800 151 and get them to come again.
