When I wrote the other post I hadn't thought about the fact he has the Xlink was connected to a 110. The OBi202 functionality would be similar but with an extra line, more slots for service providers, wifi possible with that dongle, QOS settings if you use the router on it, and file sharing with a usb drive. The XLink can connect more phones. I think I saw the one model had the ability to do 3 cell phones simultaneously.
