Features and Services
The number of timeslots is limited to 30 per conference loop. For Option 11C,
a maximum of five simultaneous conferences, each consisting of six
conference users, is supported per conference loop.
Double conferences are blocked to avoid conference chains (that is, set A and
set B are on an established call. The user of set B presses the Conference key
to call set C. Any attempt by set C to initiate another conference is blocked if
set B has not yet completed the conference).
While the originating side of a call is linked to a transfer or conference key
(that is, the originator of a transfer/conference call has not yet completed the
transfer/conference), the terminating side cannot initiate a transfer or
conference. Conference calls cannot be transferred.
A warning tone is available for conference calls. When the option is enabled,
the tone lets callers know that they are entering a conference call. The switch
for this option is preset to disable the warning tone. For information on the
switch settings for the NT8D17 Conference/TDS card, refer to Circuit card
installation and testing.
Feature interactions
500/2500 Line Disconnect
If one of the parties in the conference is connected to a 500/2500 port that is
in turn connected to a Voice Response Unit (VRU), dial tone is provided to
the 500/2500 port when all the other parties in the conference disconnect.
This feature enhancement applies in the same way to Call Transfer and
Hunting.
AC15 Recall: Transfer from Meridian 1
The use of the Conference key does not activate the AC15 Recall: Transfer
from Meridian 1 feature. Conference call is not supported because it is not
possible to have two parties on the same trunk.
AC15 Recall: Timed Reminder Recall
The conference feature is sometimes used to perform a transfer when a
controlling party establishes a call, the controlling party establishes a
conference with a third party and releases, and a call is established between
the two remaining parties.
