 | | H.323 is a set of standards defined by the International Telecommunications Union (ITU) for the transmission of real-time audio, video and data over packet switched networks, including the Internet (using IP packets.) The original standard was released in 1996 and, prior to the introduction of SIP, was the emerging standard for Voice-over-IP telephony. |
 | | H.323 fit nicely into the PSTN switching world and was consistent, in many ways, with protocols like Q.931 and Q.2931 used for call setup and management in ISDN and ATM respectively. |
 | | H.323, by contrast, must be driven through a C, C++, or C# or other programming language in which the developer can touch the H.323 driver system. |
