This reduces the need for a large number of public IP addresses. The NAT feature ensures security since each outgoing or incoming request must first go through a translation process.

Page 310: Acoustic Echo Cancellation
Administrator’s Guide for CP860 IP conference phones Acoustic Echo Cancellation (AEC) is used to reduce acoustic echo from a voice call to provide natural full-duplex communication patterns. It also increases the capacity achieved through silence suppression by preventing echo from traveling across a network.
Page 311: Background Noise Suppression
Configuring Audio Features Select the desired value from the pull-down list of ECHO. Click Confirm to accept the change. Background noise suppression (BNS) is designed primarily for hands-free operation and reduces background noise to enhance communication in noisy environments.
