UC-P100-S/UC-P110-S Phones for Skype for Business
Supplemental Guide – DOC. 8412A
Acoustic Clarity Technology
Acoustic Echo Cancellation (AEC)
Skype for Business phones employ advanced AEC for hands-free operation. The AEC
feature can be configured 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 or avoid echo when the
user employs the handset.
NOTE:
Utilizing Acoustic Echo Cancellation will introduce a small delay into the audio
path which might cause lower voice quality.
AEC can be configured using the configuration files or via web user interface.
