Change to Chairperson
Regular participants can request to become the conference chairperson using the appropriate DTMF code
(default: *78), which enabled them to perform operations designated for chairpersons only.
The Change to Chairperson via the DTMF code (default: *78) is executed only if the following settings were
configured for the MCU and the conference:
● In the Conference IVR Service - Conference Chairperson dialog box, select the Enable
Chairperson Messages check box, and select the appropriate voice messages.
For more information, see New Conference IVR Service Properties - Conference Chairperson
Options and Messages.
● When starting a new conference or defining a new Meeting Room, define the Chairperson
Password in the conference General dialog box.
For more information, see Creating a New Meeting Room.
Controlling the receipt of in-band and out-of-band DTMF Codes
The RFC2833_DTMF System Flag controls the receipt of in-band or out-of-band DTMF Codes.
When set to YES (default), the RMX will receive DTMF Codes sent in-band. When set to NO the RMX
receives DTMF Codes sent out-of-band. The RMX always sends DTMF Codes in-band (as part of the Audio
Media stream). If you wish to modify the flag value, the flag must be added to the System Configuration file.
For more information see Modifying System Flags.
Entry Queue IVR Service
An Entry Queue (EQ) is a routing lobby for conferences. Participants are routed to the appropriate
conference according to the conference ID they enter.
An Entry Queue IVR Service must be assigned to the Entry Queue to enable the voice prompts and video
slide guiding the participants through the connection process.
An Entry Queue IVR Service is a subset of an IVR Service. You can create different Entry Queue Services
for different languages and personalized voice messages.
The Collaboration Server is shipped with a default Entry Queue IVR Service and all its audio messages and
video slide. You can define new Entry Queue IVR Services or modify the default Entry Queue IVR Service.
If the audio file was not uploaded prior to the definition of the IVR Service or if you want to add new
audio files, click Add Message File to upload the appropriate audio file to the Collaboration Server.
