Acoustic Echo Cancellation
Acoustic Echo Cancellation (AEC) is used to reduce 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 the network.
The IP phone employs advanced acoustic echo cancellation for hands-free operation. Acoustic Echo Cancellation
is normally not required for calls via the handset.In certain situations, where echo is experienced by the remote
party, AEC may be used to reduce/avoid echo when the user uses the handset.
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.
