4-35
number 15 is used for the audio message deployed in Greet and Guide
conferences.
The Audio Bridge can run four conferences simultaneously, totaling up to 16
participants (4/16). To increase the maximum number of participants in a
conference to 30 participants set the Audio Bridge to 1/30. When set to 1/30
the Audio Bridge can run only one conference at a time even if the conference
includes 16 participants or less and not all the resources are used. The audio
card can support up to six gateway sessions with two participants in a session,
with a maximum of 12 participants. To enable the gateway sessions set the
Audio Bridge to 6/12. When set to 6/12, the audio cards can run only gateway
sessions and cannot be used for multipoint conferences. The audio bridge can
use units from the same audio card or from different cards.
The default setting of the Audio cards is 4/16. You can change this
configuration to suit the type of conferences that are required in your site.
To modify the audio bridge configuration:
In the Browser pane, right-click the Audio Bridge icon, and then select the
appropriate configuration, 1/30 , 4/16 , 6/12 .
The audio card settings are modified accordingly.
The total number of conferences that can be run by an MCU that contains
only Audio cards (no Audio+ cards) is determined by the configuration of the
audio bridge of each of the audio cards installed in the MCU. For example, if
the MCU contains two audio cards and one card’s Audio Bridge is set to 1/30
the maximum number of conferences is set to 5.
The total number of Audio ports available is determined by the:
• Number of Audio modules x 12
