While both standards have their champions,

the complex and competitive world of telecommunications, it’s not surprising that there is no all-embracing standard for signalling. In fact, there are two main standards: H.323 and SIP. They grew out of different roots and from different functional needs.
the reality is that they germany telegram both have an assured lifespan. Here we take a deep dive into the details of the two standards and explore their relative strengths and weaknesses.
Origins
H.323 is part of the H.32x group of standards handled by the International Telecommunication Union (ITU). It was formalised in 1996 and grew out of a need for standardisation of real-time multimedia communication over IP. Collectively the ITU-T telecommunications standards specify how calls are established and shared, and how compliant components will interact.
The SIP standard is handled by the Internet Engineering Task Force (IETF) and was formalised as a Request for Comment (RFC) in 1999. SIP has its origins in the Internet community and was designed to support call-processing functions in PSTN – later extended for multimedia such as video conferencing.
Terminal – an endpoint in the LAN, this participates in two-way communications with another terminal. By definition, it must support at least audio communication but may also include video and data.
