How do I hook this thing up?

Hooking up the Ooma device is simple, although there are various ways to do it. The basic steps are:

1. Plug the Ooma device into your cable or DSL modem.
2. Plug your home network into the Ooma
3. Plug your telephone into the Ooma
4. Go through a simple registration process
5. Make (essentially) free calls!

I had been using Vonage for a few years, so the switchover was extremely simple. If you are going from the standard landline service to Ooma (or any VOIP service), I recommend disconnecting your house wiring from the phone company wiring at the demarcation point (sounds complicated, but isn't). See info here. 

Now, just plug the Ooma device into any phone jack and ALL phones in your house will go through the Ooma service.
