H.245
H.245 is a control signaling protocol used in multimedia communication systems, particularly within the H.323 standard for voice and video over IP networks. It handles call control functions such as capability exchange, logical channel signaling, and flow control between endpoints like IP phones or video conferencing systems. The protocol ensures that devices can negotiate and manage media streams effectively during a session.
Developers should learn H.245 when working on VoIP, video conferencing, or real-time communication applications that require interoperability with legacy H.323 systems. It is essential for implementing call setup, media negotiation, and session management in enterprise or telecommunication environments where H.323 is still in use, such as in some corporate video conferencing setups or older telephony networks.
