Installing a telephone line filter or DSL filter
Sometimes, broadband Internet services that use the telephone line can interfere with phones. One of these services−DSL−often causes static on telephones. A DSL filter or telephone line filter usually solves this problem. The technician who installed your DSL service might have left some filters for you; if not, call your DSL provider 
or look in any electronics store.
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.
