Conference Media Types
Conferences can be of two media categories: Audio Only and Video and
Audio.

Audio Only Conferences

Audio Only conferences include only Audio participants and allow the use of
VoicePlus capabilities. In an Audio Only conference, participants can connect
to the conference using different network connections: PSTN/ISDN or T1-
CAS lines, cellular phones, or VoIP (H.323 or SIP). Audio only participants
can connect to conferences using VTX 1000 endpoints. VTX 1000 users
connect to conferences as audio only participants, while enjoying the same
wide band, high quality audio used by video participants.
VoicePlus offers special features such as the IVR Service, chairperson “dial-
out” inviting participants to join the On Going Conference, chairperson and
participant control of the conference via touch-tone commands (DTMF
codes), the management of voting and Question and Answer sessions, and
many more. Touch-tone commands, MGC Manager and Web controls are the
tools that are used to manage both Audio Only conferences and participants
while voice prompts are used to guide participants to the appropriate
conference. The prompts can be customized to enable multi-lingual support.
In Audio Only conference setup, only the functions, operations and icons
relevant to this type of conference are displayed in the MGC Manager, while
functions and operations relevant to video conferences are hidden and
disabled.
For detailed information about the various Audio Only conference types, see
the MGC Manager User’s Guide, VoicePlus Edition, Chapter 2, Defining
Standard Audio Only Conferences and Reservations”.
