Chapter 2 - Defining Standard Audio Only Conferences and Reservations
2-6
MCU Configuration and Audio Only Conferences
The functional modules (cards) installed in the MCU determine what kind of
conference can run on the MCU.
The Audio+ card is required to run IVR-enabled conferences and Entry
Queue and Audio Only conferences. If no such card is available, an error
message is displayed when defining any of these conferences.
T1-CAS participants are supported only with the Audio+12/24, Audio+24/48
and Audio+48/96 cards.
It is not possible to mix an ISDN Network Service and a T1-CAS Network
Service on the same Net-2/Net-4/Net-8 Network Interface module. Therefore,
to run both ISDN and T1-CAS conferences simultaneously, you must install
two separate the Net-2/Net-4/Net-8 cards. IP or IP+ cards are required to run
conferences that include VoIP participants.
IP+ cards from version 4.23 or higher are required for conferences that
include SIP participants. IP (12 or 24) cards are sufficient for H.323-only
conferences.
The VTX 1000 connection is supported with the Audio+12/24, Audio+24/48
and Audio+48/96 cards and the MGC-25.
