Businesses still have PBX systems, but the advent of digital technology means that their PBX systems now use the Internet to connect lines internally. IP PBX, or Internet Protocol PBX, allows you to connect internally. Connecting a company internally, even if they have offices in multiple locations, is a major advantage of IP PBX. It also enables you to connect externally through a digital network or by using the public wired system.
