Yealink SIP-T40P — настройка функций аудио: Устранение акустического эха [677/841]

Configuring Audio Features

661

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. IP phones employ advanced AEC for hands-free operation. AEC is not

normally required for calls via the handset. In certain situation, where echo is

experienced by the remote party, AEC may be used to reduce/avoid echo when the

user uses the handset.
