Polycom DOC2066F manual Using SilenceIT, Conference On Hold, Admittance during a Roll Call

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”.
