Using Roll Call
The Roll Call feature is used in IVR Message Service to record the
participants name and play it back when entering and leaving a conference.
The purpose of Roll Call is to ensure that all required participants are present,
and to identify the participants to one another.
Participants connecting to the conference are asked to record their names. The
system records the names and plays the recorded names when the participants
enter and leave the conference. During an IVR enabled conference, the
chairperson can request the system to play the names of all connected
participants at the beginning of the conference or at any time during the
conference. The IVR system plays the recorded list of conference attendees,
one after the other, in the order that they entered the conference. The
recordings are played to all the conference participants.
The basic Roll Call contains the following stages:
1. Participants connect to the conference, and are requested to record their
names.
2. Participants record their names. The recording is automatically
terminated after two seconds.
3. The system plays the recorded name to each participant and asks the
participant to press a pre-configured key for confirmation. The
participant may alternatively record the name again.
4. Once the participants confirm the recording, the system connects them to
the conference and announces their names to the connected participants.
5. During the conference, the chairperson can request a roll call using the
appropriate DTMF code from the endpoint’s input device. When the
system plays back the participant names, all conference participants get
to hear it using the appropriate DTMF codes. The chairperson can end
the Roll Call playback at any time.
Playing the Roll Call Confirm Record message to participants is optional. The Roll
Call Confirmation message is not played to the participant when the flag
ROLL_CALL_CONFIRMATION = YES (default), located in the Greet&Guide/IVR
section of the “system.cfg” is set to NO.
