I HAVE THE ABOVE WITH BROADBAND AND SKY AND FILTERS ON ALL PHONES BUT EVERY TIME I USE IT I EITHER GET CRACKLING ECHOING OR A HIGH PITCH SCREECHING NOISE CANYOU HELP?

Do you have your modem through a filter direct into the wall socket? or do you have it through an extension lead first?

I had a similar problem because the modem was on an extension lead and was solved when I moved it next to the wall socket.
