What is h 323?

H.323 is a standard protocol suite that is used for audio and video communication over IP networks, such as the internet. It was developed by the International Telecommunication Union (ITU) and is widely used for video conferencing, telephony, and multimedia applications. The protocol includes a set of standards that define how communication devices should connect, negotiate the call parameters, and transfer data. It supports various codecs, including G.711, G.729, and H.264, and uses RTP (Real-Time Transport Protocol) to transport audio and video data. H.323 also includes security features such as H.235, which provides encryption and authentication for data transfer. It has been widely adopted by businesses and organizations for its ability to deliver high-quality audio and video communications over IP networks.
