RMX Skins Select the skin you want. Skins modify the background and 
frames. With the top two skin options, the frames fill the 
screen with their borders touching.
These options are not available if you select any of the 
following:
• Video switching (VSW) option (RMX General 
Settings)
• Telepresence mode is On (RMX Video Settings)
RMX Conference IVR
Override default 
conference IVR 
service
Select to override the default conference Interactive Voice 
Response (IVR).
Conference IVR 
service
If you selected the override option above, enter the name of 
the conference IVR service you want to use. All RMX 
systems that could be used must have the same 
conference IVR service set up.
Conference requires 
chairperson 
Select this option to require that a video chairperson control 
the conference from his or her video endpoint system. 
When this option is implemented, the system will assign a 
15-digit password that the conference chairperson must 
enter to control the conference. The conference scheduler 
can change this system-assigned password to any 15-digit 
number.
In this case:
• The video chairperson must have a video endpoint 
system.
• The conference requires an MCU.
• All conference participants remain in the waiting room 
and cannot join the conference until the conference 
chairperson enters the conference.
H.243 chair control allows an endpoint to control the 
conference using the H.243 chair control feature. The 
chairperson can disconnect participants, force the use of a 
continuous presence video layout, and terminate the 
conference.
H.243 cascade control allows the MGC-50 or MGC-100 to 
support a cascading configuration of conferences with the 
capabilities of H.243.
Note
• Set in the RMX profile for RMX 2000/4000 devices
• The RMX 1000 system does not support the 
Chairperson feature.
