Can you get dial tone on your phone? Is the quiet line test 17070 perfectly quiet or is there any crackling when connected to the test socket behind the removable faceplate of the master socket? I suspect you have a line fault which the engineer will hopefully fix tomorrow.
Thank you for your response licquorice.
I do get a dial tone on the landline. But can’t do the quiet line test thing as our phone isn’t a touchtone one so can’t press 2 to get to that test.
Just dial a single digit to get rid of dial tone and then listen if the line is quiet. The engineer will be able to test your line when he arrives.
Absolutely no idea, it could be any number of things. The line should be absolutely quiet, a slight crackle indicates a probable line fault.
