Configuring Audio Features
809
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.
Note

Utilizing acoustic echo cancellation will introduce a small delay increase into audio path
which might cause a lower voice quality.
