Yep, those are the phones, and they don't even come close to the ease and functionality of a Panasonic system. These systems are not Vonage, that is something completely different. These are just phones that run over a network rather than a KSU with extension specific wiring and as I said above No One Touch intercomming or transfers or anything like that, everything is menu and folder driven on the phones. The Cisco's have a main router/switch that has the ports for installing the incomming Telco line and then the phones just sit on the network. If you want a phone system to connect multiple homes I would just stick with the Panasonics or a similar system and then get Vonage or a similar service. You could then just program in the phone number for each home as a one touch button to call back and forth.
