An IP PBX is a private branch exchange that uses Internet Protocol (IP) to manage voice over IP (VoIP) calls within an organization. It connects VoIP phones and traditional PSTN phones within a company, and allows them to make calls to each other as well as to the public switched telephone network (PSTN).


An IP PBX typically includes many features that are found in a traditional PBX, such as support for multiple lines and extensions, call forwarding, caller ID, and voicemail. In addition, an IP PBX can offer features that are not available with a traditional PBX, such as integration with email and calendaring systems, and the ability to make and receive calls from anywhere in the world using VoIP.


IP PBX systems can be deployed in a number of ways, including on-premises, in the cloud, or as a hybrid solution. On-premises IP PBXs are usually installed at a company's headquarters, and all calls are routed through the PBX. Cloud-based IP PBXs are hosted by a service provider, and calls are routed over the Internet. Hybrid IP PBXs combine on-premises and cloud-based components, and can offer the best of both worlds in terms of features and flexibility.
