Acoustic Echo Cancellation - Yealink SIP-T2xP Administrator's Manual

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.
Note
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.
