Just a quick point on the wireless use. I run three obi devices (2 Obi200s and 1 obi202). Due to limited space around my router I wanted to use a different section of the house for my phone/fax placement. I tested a obiwifi usb chip and felt I wasted my money, but what work out to be a better option was an EnGenius ETA1305 which is a N300 wireless media bridge/access point. Through the 3 obi units, I run 1 standard phone system and a 2 line phone system, and a fax machine, all are hardwired into the EnGenius unit. My calls are clear, with no problems, the fax machine sends and receives with no problems. Where I agree hardwired from your obi device is best, I would consider a N300 wireless access point over a obiwifi chip. The 2 obi200 units are both set up with Australian SIP numbers, so even from the other side of the planet the calls sound like the person is in the next room. in our case we use both cordless phone systems plugged into the obi units and plugged into the house wiring with 4 line phones in different parts of the house. Hopefully you will be able to solve your distance problem.
