Installing a telephone line filter or DSL filter
Any.broadband.Internet.service.that.uses.your.telephone.
line.might.interfere.with.standard.phones..The.most.common.
type.of.these.services,.DSL,.often.causes.static.on.your.
telephone. Fortunately, an easy-to-install filter removes this 
static.from.the.line..Technicians.who.install.DSL.service.
usually leave several filters for the customers; if you can’t 
find them, call your DSL provider or look in any electronics 
store.
Just plug the DSL filter into the telephone wall jack and then 
plug your phone’s base into the filter. Make a test call to 
make.sure.the.noise.is.gone.
