Chapter 6 - IVR and Entry Queue Services

6. When a participant leaves or is disconnected from the conference,
participants remaining in the conference hear an audio message
announcing the name of the participant who has left the conference.
Roll Call can be activated during different conference statuses:
• Conference On Hold
Participants who access a conference that was placed on hold, must
follow the usual connection process and record their names. However,
when participants enter conferences on hold, their names are not played
to the conference. The chairperson can request a roll call only when the
conference is reinstated and the on hold state is revoked. The list of
played names will then include the participants who connected to the
conference while it was on hold.
• Admittance during a Roll Call
When participants join or leave the conference during an on going Roll
Call, the corresponding announcement is played immediately, thereby
interrupting the on going Roll Call. When the Roll Call is resumed, the
name of the participant who left the conference is skipped (not played).
• No Other Participants Indication
When the chairperson asks for a Roll Call and there are no other
participants in the conference at that time, only the chairperson’s name
will be played.
Enabling Roll Call
Roll Call must be enabled or disabled at the conference level by assigning a
Roll Call enabled IVR Service and by enabling it in the Conference
Properties- Settings dialog box. However, if the Roll Call option is not
enabled in the IVR Message Service, it cannot be activated for the
conference.
For more details on enabling Roll Call during a conference and a list of Roll
Call DTMF options, see Chapter 4, “Roll Call”.
Using SilenceIT
The SilenceIT feature (automatic muting of detected noisy lines) is used in
conferences that were assigned an IVR Message Service to control and ensure
the quality of the audio transmission for the conference participants. When
the system detects a noisy line and mutes it, an IVR message is played to
inform the conference participants that one of them was muted due to their
