So, we ditched the home phone a couple of years back, but we've recently put our cells on no-contract plans with limited minutes. When we have months with intensive wait times with mortgage companies, or other idiots, we seem to be running thin of minutes....and I'm *NOT* going back to contract celly service.

So, I'm looking into different solutions to get home phone over interwebs and I was wondering if anyone has some cool solutions. Basically, I'd like to have one phone on each floor with internet phone service that is free.
My thought was to pick up an Obi box from Amazon and some DECT 6.0 handsets and go through Google Voice.
Any suggestions?
