Acoustic Clarity Technology
Acoustic Echo Cancellation
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. Skype for Business
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.
