Step 7 Repeat 1 to 6 for each Invite # field until you configure all required the participant invites.

Step 8 Select Invite (26 in Figure 2-4) to send the invitations.

About Cascading Conferences

Users with moderator-level access can increase MCU call capacity by cascading MCU. This option supports the bridging of several separate conferences to create very large conferences through IP connections (H.323 and SIP) and also through ISDN/PSTN connections (H.320) when operating in conjunction with a gateway.

In the Conference Control interface, cascading a conference works the same way as inviting a single participant into an existing conference. Once you create a cascaded conference, you can use the MCU to set the conference to which invited participants are connected, providing precision control of resources. In a cascaded conference, you can view participants in a tree view that displays each participant according to the conference to which each is connected.

Note If a failure occurs in a cascaded conference, local MCU users can see this status in the Create Conference window or Conference Control interface. This status, however, only appears if it was the local MCU that was lost. If the slave MCU is lost, then the user of the master MCU can view which participants are without audio/video in the Participant List tab. If the master MCU is lost, then slave MCUs do not receive any indication that there has been a failure.

Defining Conference Views

The following sections describe the tasks that users with appropriate access level can perform in the Conference View section:

•Enabling or Disabling Dynamic Layouts

•Changing the Main Conference Layout

•Changing a Personal Conference Layout

•Displaying Participant Names in Frames

•Enabling or Disabling Auto-Switch Mode

Enabling or Disabling Dynamic Layouts

Users with moderator-level access can enable or disable dynamic layouts for a conference. A dynamic layout seamlessly switches the conference video image between a wide range of layouts to correspond with the number of participants in attendance at any given time during the conference. The video image switches to a layout with frames equal to the number of participant images, to a maximum of 16. The layout changes accordingly as participants join or leave a conference.

A dynamic layout conserves bandwidth, eliminates the display of empty frames in the video image, and makes optimum use of the video image for displaying participant images. This type of layout switching is suitable for a conference with a high rate of participant traffic joining and leaving the conference or an adaptive service used for a variety of conference sizes.

Procedure

Step 1 Access the Conference View section of the Participant List tab.
