What is IP PBX?

An IP PBX (Internet Protocol Private Branch Exchange) is a business telephone system that uses the Internet Protocol (IP) to handle calls. It replaces traditional analog or digital PBX systems by routing calls over a data network. IP PBXs offer features like voicemail, call forwarding, automated attendant, and conference calling, and are commonly used by businesses to manage internal and external communications, reduce costs, and improve flexibility.
