Hi everyone!

I have a question about MCU cascading.

I know MC cascading from reading H.323v2 recommendation.

But, i'm not sure how to control media distribution.

I think MasterMC knows only capset of local terminals connected directly.

so, MasterMC can't make a SCM(selected communication mode) about all terminals.

How MasterMC knows it?

Eventually, I want to know about MP cascading excatly.

One more question.

Is SessionID in message related to logical channel and CommunicationModeCommand,

distributed by MC?

H.245 recommendation says, "Only the master can create the session identification." at p.81.

But, Netmeeting and ViewStation which I tested create session ID itselft by convention(Audio:1, Video:2). Is it right?

I wish experts advise to me.

thanks for reading.

bye.
