Active Noise Cancellation (ANC)
From Zenitel Wiki
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 ANC feature is by default active, hence there is normally no need to do any configuration.
