Acoustic Clarity Technology
Acoustic Echo Cancellation (AEC)
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
