Subject: [Sip] Basic question

Hi,

I'm fairly new to SIP, and need help: For multipoint video
conferencing, in H.323, one had the MCU that registers with the
gatekeeper. But for SIP, there are only three basic servers: Proxy,
Redirect, and Registrar - so I cannot see where a SIP "MCU" would come
in. Will it be some sort of server, or a UA that has multiple
connections? What does the architecture look like for a conference
with 3 or more SIP end-users?

Any help would be greatly appreciated.

Rupert Kruger
