Hosted, VOIP, IP, PBX what does it all mean?

Hosted – this simply means a system that is not held onsite by you but it ‘hosted’ somewhere else on your behalf by an external provider. This is a good solution for multisite businesses or business with home workers as each branch/user connects back in to one centrally hosted system.

Voice Over Internet Protocol (VOIP) – also known as IP Telephony, or Voice Over the Internet. VoIP is a new way to make and receive calls over the Internet much like sending and receiving emails. Phone calls are transferred into data and sent through the Internet.


Internet Protocol – address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication.

Private Branch Exchange (PBX) – is a private telephone network used within a company. Users of the PBX telephone system share a number of outside lines for making external and internal phone calls.
