Pros: - Easy to set up - Works right out of the box after simple setup - Works with many options for bring your own device services

Overall Review: I have been using the "OBI" device for a few years now. Using this box, I have 2 landlines into my home for around $6 per month using "CallCentric" as my vendor for calling. I love this box in how simple it is to set up and it just works. This is my second box - this one is branded "Polycom" instead of "Obihai" but they essentially are the same box. My previous was fried via a lightning surge that traveled on the ethernet connection. If you are thinking about switching to your own box instead of using the cable company's phone service, this is the box to get.
