A VoIP phone number is a phone number used with Voice over Internet Protocol (VoIP), which carries voice communications over an internet connection instead of a traditional telephone network. A virtual phone number can be used as a VoIP number when it is connected to a VoIP-based calling service such as Callvix.

The terms overlap, but they describe slightly different concepts. A virtual phone number describes how the number is provisioned and used without a fixed traditional phone line, while VoIP describes the technology used to carry voice calls over the internet. Callvix virtual numbers can be used with its cloud-based business calling platform.

A cloud phone number is a business number managed through a cloud-based phone system rather than a traditional on-premise phone system. With Callvix, a cloud-managed number can connect to users, call routing, IVR, queues, forwarding, SMS, and supported AI voice workflows.

They are closely related. A virtual phone number is the number itself, while a cloud phone system is the platform used to manage calls and communications around that number. A cloud phone number is therefore commonly a virtual business number managed through a cloud phone system.

The number is provisioned through a business communications provider and connected to a cloud calling system. Incoming calls can be routed to users, teams, IVR menus, queues, forwarding destinations, or other supported workflows, while outbound calls use the business number as the caller-facing identity where supported.
