Expert: Gerry Magill Date: 2/13/2008 Subject: Broadband feedback on house phones
Question I have recently installed broadband, and am getting high pitched feedback on my house phones. I have fitted ADSL micro filters to all sockets, and all phones. Two phones are O.K. but two phones are still screaming, why?
Answer I have never seen this before. Normally the filters work just fine.
I am guessing that those particular phone types are resonating on that frequency. They are just very sensitive to it.
Are they wireless (cordless) devices?
I have seen interference with a wireless home router and cordless phones. If you also added a wireless home router along with your DSL connection, it may be that this is causing the interference with your cordless phones.
