Chapter 4-Additional Conferencing Information
Polycom, Inc. 4-87
The following table summarizes the state (enabled or disabled) of the Automatic muting of
noisy endpoints feature depending on the ENABLE_SELECTIVE_MIXING flag setting and
the Auto mute noisy endpoints setting in the Profile Properties - Audio Settings:
Enabling or Disabling the Automatic Muting of Noisy Endpoints
The automatic muting of noisy endpoints can be enabled or disabled at the conference level
(in the Conference Profile) or at the system level, by changing the
ENABLE_SELECTIVE_MIXING flag setting.
In new MCU installations, the automatic muting of noisy endpoints is automatically
enabled on the MCU as the ENABLE_SELECTIVE_MIXING flag is set to YES and the Auto
mute noisy endpoints check box in the Profile Properties - Audio Settings tab is selected.
You can disable the automatic muting of noisy endpoints by either setting the system flag to
NO or clearing the Auto mute noisy endpoints check box in the Profile Properties - Audio
Settings tab.
If required, it is recommended to disabled the automatic muting of noisy endpoints at the
conference level, in the conference Profile without changing the flag settings.
In existing MCU sites, following the software upgrade the automatic muting of noisy
endpoints is disabled at the conference level in the existing conference Profile and has to be
manually enabled in these profiles. This option is automatically enabled when creating a
new Profile.
Enabling or Disabling the Automatic Muting of Noisy Endpoints at the
Conference Level
If the ENABLE_SELECTIVE_MIXING flag is set to YES, the automatic muting of noisy
endpoints can be enabled or disabled at the conference level in the Conference Profile - Audio
Settings dialog box.
If the ENABLE_SELECTIVE_MIXING flag is set to NO, the automatic muting of noisy
endpoints is disabled at the conference level and cannot be enabled in the Conference Profile -
Audio Settings dialog box.
