What is an H 323 device?

H. H. 323 provides standards for equipment, computers and services for multimedia communication across packet based networks and specifies transmission protocols for real-time video, audio and data details. H. 323 is widely used in IP based videoconferencing, Voice over Internet Protocol (VoIP) and Internet telephony.

Is H 323 still used?

H. 323 is as “dead” as SNA, ISDN or COBOL. While it may no longer be part of the overall VoIP strategic direction, it will continue to be used well into the next decade.

What is the difference between H 323 and SIP?
