Re: Phone line crackly for several weeks now. Website sending me round in circles.
Have you checked this with another handset?
Also worth disconnecting any extension that maybe connected to the line. You can check this by removing the smaller faceplate off the mastersocket you will see another phone port behind it plug the phone direct into that port and test the line again.
If this does not resolve the issue then please call customer care once we return out of lockdown.
