Building on this proposed setup, I wonder if I could do the following?...Most home phone wiring has 4 wires. A single phone line only uses 2 of these. There are 2-line splitters available that separate the 4 wires into two 2-wire jacks, generally labeled LINE1 and LINE2. You would use a splitter to connect the PHONE (LINE1) and WALL (LINE2) ports from your hub to the house wiring via a wall jack. You would use another 2-line splitter in another wall jack to connect the scout's WALL port to LINE2 of the splitter (thus connecting the WALL ports from the hub and scout to the same pair of wires). An extension phone could be plugged into the LINE1 jack on the splitter, corresponding to the pair of wires connected to the hub's PHONE port.
In theory, this should work. Can't speak for it in practice...
Splitter as suggested sending the "Phone" (LINE 1) and "Wall" (LINE 2) port outputs throughout my home. On a phone jack located on a different floor than the Hub, install another splitter. From that splitter, LINE 2 into the Scout "Wall" port. Then...connect a separate phone into the "Phone" port on the Scout and accomplish a true second line (Premier feature). Would this work?
I believe the setup described above would only get the Scout on a different phone jack (answering machine capability, but no second line as the extension phone as described would be connected into the LINE 1 jack?
