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.
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.
