By default, all Audio Only conferences are run on the Audio+ cards to enable
the IVR system functionality.
Video conferences started on MCUs that include both the Standard Audio and
the Audio+ cards use the Standard audio card by default, unless an IVR
service is assigned to the conference. In such a case, the conference is run on
the Audio+ card. Video conferences using the Audio+ card have the majority
of the VoicePlus capabilities such as the use of DTMF codes during the
conference.
Video conferences started on MCUs that include the Video+ card have
additional features, such as Quad Views, Visual Effects, and the activation of
the Click&View application on the participant’s endpoint screen.

• Running Video Switching conferences on the Standard Audio card limits the
maximum number of participants in a conference to 16 (12 video and 4 audio
only). This number of participants can be increased to up to 30 participants
when configuring the Audio Bridge component of the standard Audio card to
1/30 in the “system.cfg”. For more details, see the MGC Manager User’s
Guide, Volume II, “Setting Large Video Switching Conferences” in Chapter 1.
• With the Audio+ card, up to 100 participants at 128 Kbps can connect to one
Video Switching conference (without special configuration).
• The Audio+ 12/24, 24/48 and 48/96 cards support T1-CAS participants.
