Cloud-based phone systems use the internet (including Wi-Fi) to connect callers. With Voice over Internet Protocol (VoIP) technology, telecom providers like Ooma allow people to make calls from iOS and Android devices as well as standard VoIP phones.
As a result, customers get greater flexibility and mobility that they simply can't find with traditional landline phones. You still get many of the great features you often find on your mobile device - voicemail, 911 access, messages, call waiting, blacklisting, and more - but at a fraction of the cost. And, since phone calls are placed in the cloud, you can enjoy all of these features in the cloud.
