Roll Call Roll Call is a feature of the IVR Message Service 
used to record the participants name and play it back 
when entering and leaving a conference. 
The chairperson can request the system to play the 
names of all connected conference participants at 
the beginning of the conference, or at any time 
during the conference.
This option can be enabled only when the Roll Call 
option is enabled in the IVR Service assigned to the 
conference. When enabled for the conference, the 
participant records his/her name upon connection to 
the conference and the chairperson can request a 
roll call in which the recorded names of all 
conference participants are played back to the 
conference.
If the Entry Tone and Exit Tone are enabled for the 
conference, the participant’s name is played when 
the participant enters or leaves the conference. 
If the Roll Call option is disabled for the conference 
but enabled in the assigned IVR Service, the 
participant name is recorded. The Roll Call can be 
enabled during the On Going conference, but Roll 
Call cannot be requested by the chairperson.
