Command Purpose
Step 1
Router(config-voiceport)# echo-cancel enable
Enables the cancellation of voice that is sent and
received on the same interface. Echo cancellation
coverage must also be configured. The default is
that echo cancellation is enabled.
Note Not valid for four-wire E&M interfaces.
Use no echo-cancel enable to disable the
feature.
Step 2
Router(config-voiceport)# echo-cancel coverage {8 | 16
| 24 | 32}
Adjusts the echo canceller by the specified number
of milliseconds. The default is 16.
Step 3
Router(config-voiceport)# non-linear
Enables nonlinear processing (residual echo
suppression) in the echo canceler, which shuts off
any signal if no near-end speech is detected. Echo
cancelling must be enabled for this feature. The
default is that nonlinear processing is enabled.
