- We give you a look at Ooma in this episode. Ooma is a service that provides free phone calls within the United States. All you need to do is buy the Ooma Telo box and connect it to your home network, and you're up and running. Calls within the United States are then completely free. They also have the Ooma Telo handset, which almost acts like a smartphone for your home phone service, and a monthly Ooma Premier service that adds a ton of calling features to your package.
