Acoustic Echo Cancellation
Acoustic Echo Cancellation (AEC) is used to remove acoustic echo from a voice communication in order to improve
the voice quality. 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. Echo cancellation is
achieved using the echo canceller.
Utilizing acoustic echo cancellation will introduce a small delay increase into audio path which might cause
a lower voice quality.
Procedure
AEC can be configured using the configuration files or locally.
