We just got our DSL service on June 2, 2008.
Before it started. The DSL service sent us a kit to set up. The filters they sent us was wired for the one line phone. It did not pass through the second line. We did not need a filter for the second line but I have read somewhere that it is good to have a filter on the second line to prevent cross talk from the DSL.
So I got three of these filters for the three two line phones. I had use the one line filters for the one line phones.
It has been over a week and we have no problems with our phones on both lines.
