In certain province video demonstration, MCU(support 323) hangs one 320 terminal set and four 323 terminal. After start data conference host, 323 terminals can call in, but 320 terminals can’t call in.
End data conference server, restart, let 320 terminal join the data conference first, then call in four 323 terminals, everything is normal.
The reason for this situation is: the data conference call that started by 323 terminal is NETMEETINGN call on network; it has a specialty that it will host one meeting when it starts a call. In surface, it seems that 323 terminal joins a meeting, but in fact, it is that the data conference server joins a conference that hosted by 323 terminal, so 320 terminal can’ join the meeting. But this is only one case, there may be other reason can cause this situation. In the present case, if we make same kind of demonstration, we’d better make 320 terminal join the conference first to avoid demo failure
