Active Noise Cancellation (ANC) is a feature in the Zenitel IP devices. The purpose of the ANC is to cancel out the surrounding background noise and at the same time keep the voice signal intact.

Typical background noise could be noise from an air conditioner, a factory floor or a truck engine. The Active Noise Cancellation feature is by default active, hence there is normally no need to do any configuration.


IC-Edge mode

Log in to the Edge Controller, and navigate to Edge Controller > System Configuration > Call and Audio. The ANC feature can be disabled (or enabled) per device under the column "ANC":

ICX-AlphaCom mode

In an ICX-AlphaCom system the Active Noise Cancellation is configured from AlphaPro. Select the Users & Stations window.

In the field Noise Reduction, select the value "1" to enable the ANC feature, or "0" to disable.
