Hi my landline phone has stopped working due to a continuous buzz when I pick it up. We have taken the phone outside and tried it on the dmark box and we get the same thing. Even bought a new phone,same problem. This is confusing me very much though because my dsl still works and it has to have a dial tone to work. All the filters are plugged up. I have went over everything several times. Oh and when some one tries to call our house phone all they get is a busy signal. Please help... we have been out of phone for 6 days and the phone company will not send anyone out to have a look without me paying this huge fee. Thanks a lot
