Dear John, I would like to begin by thanking you for you help. As you know we had serious RFI with an ISDN line coming into the building. The problem occurred after the ISDN line exited the router as an analog line. We tried everything, we thought (including other filters). We placed two of your filters on the phone line (one at the router and one at the phone). They worked great!
Thanks again John for you support and good product!
Sincerely,
G.G.
