Acoustic Echo Cancellation (AEC)
Yealink phones employ advanced AEC for hands-free operation. You can configure the AEC feature to remove the echo
of the local loudspeaker from the local microphone without removing the near-end speech.
AEC is not normally required for calls via the handset. In some cases, where echo is experienced by the remote party,
AEC may be used to reduce/avoid echo when you use the handset.
Note
Utilizing acoustic echo cancellation will introduce a small increase of delay into an audio path which might cause a lower
voice quality.
