Also note, this system works over your NETWORK (not your phone wires). It will connect to up to 4 standard phone lines (or Internet-based VoIP service) but the connection between the phones and the UCM6204 "base" are done over a Ethernet NETWORK. The bad news is that if you only have phone lines running everywhere (2 or 4 wires only) then you will have to run new wiring. The good news is that if you already have a computer network and computers at each phone location, these phones can be connected to that existing network. (If you only have one network jack per location, the phones' built-in network switch lets you "pass" the network connection through the phone to your computer so both can be connected).
