👉 Interior Outbound Exchange (iOEX) is a protocol that enables direct, secure, and efficient communication between internal systems within a network, bypassing traditional external interfaces like IP phones or PBXs. It facilitates the exchange of voice, video, and data messages directly between devices, such as phones, computers, and servers, using a standardized framework. This reduces latency, minimizes network congestion, and enhances scalability by eliminating the need for intermediary hardware or complex routing. iOEX supports both synchronous (real-time) and asynchronous (store-and-forward) messaging, making it versatile for applications like conference calls, instant messaging, and remote collaboration, while improving overall network performance and user experience.
