If no dial-in number is defined, the system allocates the dial-in number
according to the settings in the Web Configuration dialog box in the
MGC Web Server Manager application.
When the Web Defaults – Allocate Permanent Dial-In number is enabled
in the Web Configuration dialog box, the MGC Web Server allocates a
dial-in number for the “Meet Me Per Conference” conference when the
conference is saved to the database. This number remains assigned to the
conference indefinitely regardless of the system resources status. In such
a case, the MCU will allocate the dial-in number for the conference when
the Meeting Room is activated. When the Allocate Permanent Dial-In
Number option is disabled, the dial-in number for the conference is
allocated by the MCU only when the conference is started. The assigned
dial-in number is the MCU number defined in the Network Service. If no
number is defined for the MCU in the Network Service, the system
allocates the first free number in the dial-in numbers range defined in the
Network Service.
When disabled, the dial-in number for the conference is allocated by the
MCU only when the conference is started.
6. The list of dial in numbers assigned to the conference is displayed in a
table format. The first column displays the Network Service name. The
Phone 1 and Phone 2 columns display the first and second phone
numbers assigned to the conference.
If the conference includes T1-CAS audio only participants and the MCU
is configured to allow T1-CAS participants in audio conferences, you
can manually allocate the dial-in number for the T1-CAS participants.
If participants in the same conference use different Network Services, the
conference may be assigned different phone numbers for each of the
Network Services used by the participants to connect to the conference.
In such a case, use the manual allocation method.
If you are defining a Meeting Room with Entry Queue access you do not need
to assign a dial-in number to the Meeting Room (unless you want it to be
accessed by dial-in participants directly, without accessing the Entry Queue
first). If the dial-in number is automatically allocated by the system, and you do
not want the Meeting Room to be accessed directly (and to save dial-in
numbers), delete it from the Meet Me Per Conference dial-in numbers table
once the conference is added to the database or scheduled on the MCU.
