Wi-Fi calling usually refers to a mobile carrier feature that carries cellular calls over a Wi-Fi connection when cellular coverage is limited. Business VoIP is a broader phone service that uses IP networks and may include business numbers, extensions, routing, auto attendants, desktop applications, and centralized administration.
Both can improve calling in the right environment, but they solve different problems. Wi-Fi calling can help an individual mobile device maintain carrier service, while business VoIP is designed to manage communications for users, departments, and locations.
