Automatic Muting of Noisy Endpoints
The Collaboration Server can detect AVC-enabled endpoints with a noisy audio channel and automatically
mute them, reducing the noise heard by other conference participants. When the auto muted endpoint
becomes the speaker the endpoint is automatically un-muted by the system. If the speaker halts his/her
conversation and the line still emits noises, the endpoint will be automatically muted again.

becomes the speaker the endpoint is automatically un-muted by the system. If the speaker halts his/her
conversation and the line still emits noises, the endpoint will be automatically muted again.
When the endpoints are automatically muted by the MCU, no indication is displayed in the Collaboration
Server Web Client or RMX Manager as the system does not consider it as a deliberate mute.

Guidelines for Automatically Muting Noisy Endpoints
The automatic muting of noisy AVC-enabled endpoints can be used according to the following guidelines:
● The Auto mute noisy endpoints check box in the Profile Properties - Audio Settings dialog box is
enabled only when the ENABLE_SELECTIVE_MIXING flag is set to YES (default).
● It affects only AVC-based and audio only endpoints (non-SAC endpoints)
● It does not affect SVC-based endpoints
● It is supported in CP conferences and in Mixed CP and SVC conferences.
● In a mixed CP and SVC conferences, only the AVC-based endpoints can be automatically muted. If
● It does not affect SVC-based endpoints
● It is supported in CP conferences and in Mixed CP and SVC conferences.
● In a mixed CP and SVC conferences, only the AVC-based endpoints can be automatically muted. If
the noisy endpoint is SVC-based, its audio channel will not be sent to the AVC-based endpoints, but
it will be sent to the other SVC-based endpoints.
● MCU reset is not required when changing the ENABLE_SELECTIVE_MIXING flag setting.
● When upgrading from a version prior to 8.1, the Auto mute noisy endpoints option is not automatically
● When upgrading from a version prior to 8.1, the Auto mute noisy endpoints option is not automatically
enabled in the existing Profiles and it has to be manually enabled, if required.
In new Profiles that are created after the upgrade, the Auto mute noisy endpoints option is
In new Profiles that are created after the upgrade, the Auto mute noisy endpoints option is
automatically enabled.
● If your conferencing environment includes the Polycom DMA, the conferences that are started from
the DMA will not include the Auto mute noisy endpoints parameter as it is not part of the DMA Profiles.
In such a case, when the parameter setting is unknown, the system will enable or disable the
automatic muting of noisy endpoints according to the flag setting - if the flag is set to YES, it will be
enabled in the conference.
● Sounds with the frequency of noise, such as applause and certain background music, may be also
be muted.
