*Your one-time purchase of the ooma Hub™ device means you won't owe monthly charges to ooma for making unlimited long-distance calls in the US using the ooma system for the life of the product. There may be calls, such as 411 calls, where there is an associated transactional service fee, in this case currently $0.99. ooma will provide a list of those numbers and associated fees on its Web site. Should you want the assurance of a landline for traditional 911 service and as an integrated backup in the event of Internet and power outages, you will still save on long-distance calling. Please note that if you subscribe to ooma Premier after the free trial, we will add call forward busy ("CFB") when we provision your line, for which you may owe your landline phone company associated charges. ooma will not change your caller-ID subscription, your long-distance carrier plan, or your local calling package. You may also choose to use the ooma system without a landline. Use of ooma's service is subject to review and acceptance of our Terms & Conditions.
