I want to know the answer to the following question:
What do systems with no MCU use in order to perform multipoint conferencing?
All the background I'm provided with is that "These use a standards-based H.323 technique known as "decentralized multipoint", where each station in a multipoint call exchanges video and audio directly with the other stations with no central "manager" or other bottleneck.". Is that enough to answer the question?
Answer: yes
