Group call-out
Each ICB card supports up to 64 group call-out lists, each with up to 61
telephone numbers. Each telephone number can be up to 31 digits in
length.
Each ICB card supports up to 64 group call-out lists, each with up to 61

The administrator defines group call-out lists through the BUI (see
). The system saves the information on
the ICB PCMCIA disk.
The administrator must define the following options for each group list:
•
number of dial-out retries allowed (range: 1-3, default: 1)
•
time between each dial-out retry (range: 15-90 seconds, default: 30)
The chairperson on an active conference can call all members of a
group call-out list by dialing the following: *2 <group list number> #. The
ICB dials out to all the telephone numbers in the requested group
call-out list simultaneously. If there are more than 31 numbers on the
group call-out list, the system requires two ICB cards.

ICB dials out to all the telephone numbers in the requested group
call-out list simultaneously. If there are more than 31 numbers on the
group call-out list, the system requires two ICB cards.
When the system uses two ICB cards in a group call-out, the primary
card divides the group call-out list into two groups. The primary card
dials one group of numbers and sends the second group to the
secondary card over the TCP/IP LAN. The secondary card then dials
the second group of numbers. The system dials out both groups of
numbers simultaneously.

the second group of numbers. The system dials out both groups of

The ICB card dials out by allocating a free port and originating the call
on it. The system does not connect the port to the meeting, until the call
successfully completes. After the ICB card originates the call, it plays a
specific prompt and keeps repeating the prompt for a number of
seconds (determined by the administrator). The default configuration
forces the called party to respond by dialing a star * during this interval.
When the ICB card detects the correct response, it connects the call to
the meeting. If the ICB card does not detect the correct response within
the defined time and the defined number of retries, the ICB card
disconnects the call.

Note: The administrator can configure the call to complete without
requiring the called party to enter a star *. This option enables the
connection to paging systems and auto-attendants.

The system limits group call-outs to the number of available ports on a
conference. When a chairperson uses a list containing 61 numbers,
and the meeting has 20 free ports, the system dials only the first 20
telephone numbers.
