Enable Acoustic Fence

Acoustic Fence suppresses background noise while you are on a call, which enhances call audio quality for call participants.

The Acoustic Fence setting does not display on the phone by default, so if your system administrator has enabled the feature option to display on your phone, you can enable or disable Acoustic Fence.

Acoustic Fence works with handsets or headsets. However, only headsets connected to the RJ-9 port on the phone support Acoustic Fence. Acoustic Fence is enabled by default on the handset, disabled by default for a connected headset, and not supported with USB or Bluetooth headsets.


  1. Navigate to Settings > Basic > Preferences.
  2. Select Acoustic Fence and select Enable.
