Conference Access for Dial-in Participants
A conference can be accessed by dial-in participants via Entry Queue,
conference IVR queue or directly.
Conference IVR
Interactive Voice Response (IVR) is an application that allows callers to
communicate with the conferencing system over the DTMF input device such
as telephone (audio participants) or the endpoint’s remote control (video). It
automates the connection to the conference and enables various requests
during the On Going conference.
Different IVR Services can be created, allowing customization of the
menu-driven scripts and voice prompts to meet different needs. The IVR
Services are assigned at the conference level, and different conferences may
use different IVR Services, or the same IVR service can be used for all
conferences.
In IVR-enabled conferences, the caller enters the conference IVR queue as
part of the connection process. This ensures that only authorized callers join
the conference. Participants can request the Operator’s help while waiting in
the conference IVR queue or during the On Going conference. The operator
can join the conference and personal assistance can be provided only from the
MGC Manager. The IVR Service also enables the participants and the
conference chairperson to perform various operations via their touch tone
telephone keypad during the On Going conference.
Entry Queue
Entry Queue is a call routing method in which all participants dial the same
dial-in number and then they are routed to the appropriate conference
according to the conference Numeric ID or the conference/chairperson
password. Callers are guided to the conference using menu-driven scripts that
are part of the Entry Queue Service. The user inputs touch-tone signals in
response to voice prompts. The Entry Queue Service is a subset of the IVR
Service and behaves in the same way.
IVR-enabled conferences and conferences accessed via the Entry Queue
require the installation of the Audio+ card in the MCU.
In all Audio and Video conferences, the IVR Service must be assigned to the
conference to enable the DTMF code input by the participant and chairperson.
