Have you reported this to your ISP ? Is there any noises on your line,?
If it is down to the ISP then probably it would fix the problem
But if it down to the line it's self or anything in your home then probably it won't
You need to report it as a fault to your ISP if they refuse to help then repeat but in a more formal approach, if you are able to hear audible noise on the line when doing the bt quiet line test Best when using a corded phone in the test socket behind the faceplate, dial 17070 option 2 use secrecy button if your phone has one if not cover bit you speak into, during the test all you should hear is the recorded announcement playing over & over ,
Anything else could be a sign of a line fault, if there is noise (crackling or whirring ect ) then you can report this as a voice fault to BT or your telephone provider if not BT retail , they will arrange an engineer's visit, But best to repeat the QLT at a few different times of the day, to see if it's intermittent or constant ,if constant then you should have no worries regarding any callout charges , as the engineer should be able to hear it himself but don't mention the broadband or they will point to your ISP
You really need to establish what type of fault you have,
Voice (PTSN) OR ADSL fault noise is often a way of differentiating between them
As if there is no noise and phone is working as it should then you would have to contact your ISP in order for them to send an engineer if needed ,as it's they who have a contract with openreach for the adsl (data) and who ever you pay line rental too has a contract with them for the voice part (PTSN)
