Chapter 5 - Meeting Rooms and Entry Queues
5-2
The ISDN/PSTN/T1-CAS dial-in numbers allocated to a Meeting Room can
be automatically allocated by the MCU based on the dial-in numbers
allocated to it by the carrier or manually during the Meeting Room definition.
Once the Meeting Room is saved on the MCU, the conference chairperson or
the first participant who dials into the conference automatically activates it.
Other participants can join the conference by dialing in to it. If dial-out
participants are also defined for this conference, the system automatically
dials out to these participants when the conference is activated. The operator
or conference chairperson can lock the conference to additional dial-in
participants at any time. When the conference is terminated, the system
checks the Meeting Room recurrence settings. If the Meeting Room is still
valid for re-activation, the Meeting Room remains inactively in the system,
waiting for another initiating call. Otherwise, the Meeting Room is deleted
from the system when the conference ends. An operator can delete the
Meeting Room through the MGC Manager to prevent its re-activation.
The number of Meeting Rooms is limited to about 2000. If you need more
than this, you can use Ad Hoc conferencing which enables you to instantly
start and connect to multipoint conferences from your endpoint without prior
reservation or scheduling. For more details about Ad Hoc conferencing, see
MGC Manager User's Guide, Volume II, Chapter 3, “Ad Hoc Conferencing
and External Database Authentication”.
Entry Queues
An Entry Queue is a special routing lobby to which one or several dial-in
numbers are assigned. Participants are guided by voice prompts which are
part of the Entry Queue Service to connect to this lobby and are routed to their
destination conferences according to the conference Numeric ID or password
that they enter using touch-tone signals (DTMF codes). Entry Queues remain
in a passive state when there are no participants in the queue and they are
automatically activated when a participant dials the Entry Queue number.
The Entry Queue makes it possible to use a limited number of PSTN/ISDN/
T1-CAS dial-in numbers for all the conferences and to use toll-free numbers
for conferences which are charged to the meeting organizers.
Entry Queues that were defined for video conferencing can also be used for
Audio Only conferences, provided that the audio algorithm is set to G.711
(telephone standard). This means that there is no need to define separate
Entry Queues for Audio Only conferences. However, if the VTX 1000
