  1. Create a new video conference.

  2. Find a conference created before.

  3. Sort conferences by name, start date, and end date.

"General" tab

/mcu/media/conferences_general/en.png

In this section, you can schedule video meetings and adjust their settings. You may have to take the following steps.

  1. Specify the conference name.

  2. Set the conference PIN. In this case, you will be able to enter the PIN either as a DTMF command or in the call string format.

  3. You create a virtual room by default. If you check the Set time limit box, you will create a scheduled meeting with the start and end date.

  4. Select the maximum number of participants.

  5. Check the Auto redial box to make sure that participants can be re-invited to the conference if the connection is lost. If the operator of a video conferencing server disconnects a participant on purpose (via web interface), auto dialing will be disabled for this conference session.

  6. Enable the display of participants' names during a meeting.

  7. To stream a conference to external RTMP sources over the Internet, enter the URL address of an RTMP server.

  8. Select the participant whose layout will be used for recording or streaming. You will be able to select a participant who has been added before. If no participant is selected, the global layout will be captured.

  9. Enable recording when at least one participant joins the conference.

  10. Disable recording when all the participants leave the conference.

"Participants" tab

/mcu/media/conferences_participants_list/en.png

This section enables you to add participants and configure their audio/video devices. It allows you to:

  1. Add a new participant. Users can be selected separately or in bulk. Then, you can view the list of added users.

  2. Find a user by name.

  3. View information about an invited participant.

  4. Enable/disable a participant's camera.

  5. Mute/unmute the microphone.

  6. Enable/disable speakers.

  7. Make sure that a user does not receive video from other conference participants.

  8. Disable automatic redial if the connection is lost.

Note

You can enable automatic redial participant feature for all participants in the General tab on the conference creation page.

9. Remove a participant from the conference.

"Layouts" tab

Here, you can set a conference layout. There are two layout types: for all participants and custom.

For all participants is a standard conference layout displayed to all participants who don't have a custom layout, e.g., it will be displayed to a participant who joined the conference using a PIN.

Custom layout can be configured for any participant when you create a conference or in real time during an ongoing conference. Real-time layout changes apply only for an ongoing conference, so once the meeting ends, the layout will disappear. Every participant can have only one custom layout.

Active speaker is a layout displayed to a participant speaking at the moment. It will be possible to select video windows that will be displayed to the active speaker.

Tip

To use the layout, you need to add the Active speaker window to other layouts created for this conference.

Tip

We suggest using individual layouts as little as possible during a conference to save server resources.

/mcu/media/mcu_conferences_layouts/en.png

In the Layouts section, you will be able to:

  1. Create a new layout.

  2. Delete the selected layout, if necessary.

  3. Check the Automatic layout box, if you want the layout to be generated automatically depending on the number of participants invited to a conference.

    • Empty: the window will remain empty and will be used for a participant who may be invited during an on-going conference.

    • Fixed participant: one of the participants will be permanently displayed in the selected window.

    • Active speaker: the participant, who is speaking at the moment, will be displayed in the selected window.

    • Autofill: one of the conference participants added automatically will be displayed in the video window.

    • Content: the window will be used for displaying the content shared by participants, e.g., desktop or slides.

7. Check Enable time rotation mode if you want to change a displayed participant in the window every 3 seconds.

Note

This feature is available only for the participants who were added to the layout using the Autofill function.

8. Click Fill windows automatically if you do not want to add participants manually.

9. Click Reset all windows to set a new layout.

For the sake of convenience, TrueConf MCU provides a large variety of layouts:

Joining a conference

TrueConf users can join a conference hosted on TrueConf MCU using the following call string formats:

1. Via SIP protocol (if its use is enabled):

  • #sip:<pin>@<server_name>, where:

    • <server_name> the DNS or IPv4 address of the PC where TrueConf MCU is installed on.

    • <pin> is a conference PIN.

  • #sip:@<server_name>,<pin>#, where:

    • <server_name> the DNS or IPv4 address of the PC where TrueConf MCU is installed on.

    • <pin> is a conference PIN.

  • #sip:@<server_name>, where:

    • <server_name>the DNS or IPv4 address of the PC where TrueConf MCU is installed on. In this case, a participant has to enter a PIN with the dialer to join a conference.

2. Via H.323 protocol (if its use is enabled):

  • #h323:<pin>@<server_name>, where:

    • <server_name> the DNS or IPv4 address of the PC where TrueConf MCU is installed on.

    • <pin> is a conference PIN.

  • #h323:@<server_name>,<pin>#, where:

    • <server_name> the DNS or IPv4 address of the PC where TrueConf MCU is installed on.

    • <pin> is a conference PIN.

  • #h323:@<server_name>, where:

    • <server_name>the DNS or IPv4 address of the PC where TrueConf MCU is installed on. In this case, a participant has to enter a PIN with the dialer to join a conference.

Tip

If a user calls to TrueConf MCU without a PIN (using #h323:@<server_name> or #sip:@<server_name> call string format), he/she will get into the Pending connections column until entering the PIN or being added to the conference by the administrator.
