Inviting Participants Using Advanced Settings

Inviting Participants Using Advanced Settings

All users can invite multiple participants into a conference at the same time in the Advanced Invitation tab of the Conference Control interface. As each invite field can accommodate multiple participant numbers with separators, you can use this tab to invite a large number of participants at the same time. All users can also select a lower bandwidth rate with which to connect individual participants.

In the Advanced Invitation tab, all users can also drag and drop participant images into preferred positions in the layout of each conference view that the conference supports. All users can also set the layout which invited participants see when joining a conference.

In a cascaded conference, all users can choose which MCU actually invites the participant.

Procedure


Step 1 In the Conference Control interface, click Advanced Invitation.

Step 2 In the first Invite # field, enter the participant contact numbers. You can enter multiple numbers separated by the invite sign (**).

Step 3 In the Display Name field, enter the name you want to appear when the participant enters the conference.

Step 4 In the Kbps field, choose the bit rate that the MCU uses when inviting a participant to a conference. Choose default for optimal bit rate performance.

Step 5 In the MCU field, choose a cascaded MCU conference to which invited participants connect.


Note This step is only for cascaded conferences.


Step 6 (Optional) To configure advanced features, follow these additional steps;

Additional control features appear in the Advanced Invitation tab.

In the Participant Layout area click Change.

A dialog box appears displaying a list of the current layouts available in the current conference.

Drag and drop the Voice activated frame button into the preferred position in the Layout display frame that appears in the Conference View section.


Note You can set a position for the participant image in all layouts that the conference currently supports.


At the end of each participant row, choose from the list the number of the conference video layout you want to display to the participant upon entry into the conference. Choose L to display the local view of a slave conference.

A slave conference on an EMP-enabled MCU has two views:

The local (slave MCU conference) CP view

The view that the master MCU broadcasts.

An Operator of the slave conference should be able to switch the view for each participant in the slave conference so that the participant can see the view broadcast by the master or the local view. This feature is useful in large cascaded conferences where each site has a local operator. Most participants at the local site see the view broadcast by the master MCU, but the local operator can see the local view of local participants.

You can enable a local view of a slave conference in the Edit View dialog box.

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

Step 8 Click Invite to send the invitations.

Using Quick Invites to Invite Conference Participants

Cascading Conferences

Users with Moderator-level access can increase MCU call capacity by cascading MCUs. 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 EMP or MCU that was lost. If the EMP of a 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 EMP of the master MCU is lost, then slave MCUs do not receive any indication that there has been a failure.


Procedure


Step 1 Access the Participant List tab.

Step 2 Invite another conference on the host MCU or on another MCU by entering the number in the Invite # field and clicking Dial.

The invited conference and connected participants appear in the host conference participant list in the Participant List tab.


Inviting Participants to a Cascaded Conference

All users can invite participants to a cascaded conference in the Advanced Invitation tab of the Conference Control interface.

Procedure


Step 1 In the Conference Control interface, click Advanced Invitation.

Step 2 In the MCU column, choose the conference to which the invited participant connects upon acceptance of the conference invite.


Viewing Participants in a Cascaded Conference

In the Conference Control interface, you can view participants in a cascaded conference in a hierarchical display in one of the following two ways:

Normal View—All conference participants appear in a single list. Cascaded participants appear without any indication of the cascaded MCU connection.

Tree View—Conference participants appear in an expandable tree view showing cascaded MCU connections to the conference. Click the plus sign (+) next to the name of the cascaded MCU to expand the tree showing cascaded conference participant details.

Procedure


Step 1 Access the Participant List tab.

Step 2 Click Normal View to display cascaded conference participants in a single list.


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 Conference Layouts

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.

Step 2 Click Change.

A pop-up appears, displaying a list of currently available layouts for the current conference.
