meeting organizer via the WebCommander application (through the 
WebCommander site). 
In Audio Only and Video conferences that are accessed from an Entry Queue 
or have an assigned IVR Service, the operator can assist dial-in participants 
by greeting and guiding them to the appropriate conference, or by helping 
them join the conference if they have failed to enter the required information 
(password). 
Once the conference has begun, operator assistance continues to be available 
upon request, by telephone keypad or other DTMF input device (e.g. remote 
control). During a conference, the operator can also manage Question-and-
Answer and voting sessions, connect and disconnect participants, mute/
unmute participants, start a lecturing session, place the conference on hold 
and lock/unlock the conference to dial-in participants. 
However, an On Going conference can also be managed by participants or by 
the chairperson without the operator’s assistance. Actions that can be 
performed by the participants or the chairperson, are defined in the IVR 
Service that is assigned to that conference. This type of conferencing requires 
the installation of the Audio+ card in the MCU.
Participants Queue
The Participants Queue is a list of all participants waiting for the operator’s 
assistance or who are on hold - in all conferences, regardless of the 
conference they belong to. The Participants Queue is mainly intended for 
attended conferences. Using special toolbars, command buttons and options 
provided in the MCG Manager Participants Queue window, the operator can 
easily move the listed participants from the Participants Queue to their 
destination (On Going) conference.
Greet and Guide conference (Welcome Queue)
Greet and Guide Video conferences (with an AV Message Service assigned to 
them) can either run unattended, or may be managed by an operator. 
However, because no IVR Service is available, the participants or the meeting 
organizer cannot control the conference from their endpoint.
For a detailed description, see the MGC Manager User’s Guide Volume II, 
Chapter 2, “AV Message Services and Greet and Guide Conferences”.
