Yes, but note that if the endpoint receives a multipointconference indication it should wait for the communicationmode command.

H.323 8.3.5 has the following statement It is presumed that the CommunicationModeCommand is defining the modes of a conference and is therefore sent after the multipointConference indication which notifies an endpoint that it must comply with the commands of the MC. Endpoints should wait for a CommunicationModeCommand before opening logical channels when they have received a multipointConference indication.

Hi everyone

in multipoint conference, when the terminal joining the conference has received the H.245 CommunicationModeCommand from MC, Should we open logical channels using the OpenLogicalChannel-OpenLogicalChannelAck sequence?
