I just had OV installed Friday and a 5 year old could go thru the online process of setting it up, its the rewiring of the box that is a little more involved. I had a contractor from 180 connect who was great. I already had Vonage at one time, so all he had to do was disconnect Verizon at the box and hook up the cable that feeds back into it. If you are not porting your number, it should be a breeze if you can handle the wiring. If you are porting like I did, they still have to come and install it.
