I cannot complain about this adapter. It does what it supposed to. Installation and set-up took about 15 minutes, worked right away. The devise allowed me to keep my wireless phone connected to the regular (landline) phone line, and in parallel - be connected to the internet phone. Depending where I get a ring from - it will automatically re-route the call to the phone. I believe it also allows to do some simple call forwarding, but I haven't tried that yet.. Overall - I am very satisfied with the devise, and you cannot beat the price..
