I have an interference problem on my cable phone line . It is a kind of crackling buzzing sound that is not always there but seems to build up as the phone call progresses. . . I have virgin media engineers out twice now They have relaid the cable in the street and also through my front garden.This has not solved the problem. I have disconnected all my internal wiring and just plugged the phone into the master socket. This still does not work. The phone is fairly new. I have an engineer coming out again in 10 days. Has anyone got any idea what is causing the problem? as i suspect the engineer will not have a clue thanks
