Parameters
convergence-rate value: Sets the convergence rate of comfort noise amplitude, in the range of 0 to 511.
The greater the value, the quicker the convergence.
max-amplitude value: Sets the maximum amplitude of comfort noise, in the range of 0 to 2048. The
greater the value, the greater the noise amplitude. The value 0 indicates that the system performs only
nonlinear processing and does not add comfort noise.
mix-proportion-ratio value: Sets the comfort noise mixture proportion control factor, in the range of 0 to
3000. The greater the value, the higher the proportion of noise in the hybrid of noise and voice.
talk-threshold value: Sets the threshold of two-way talk, in the range of 0 to 2.
Usage guidelines
The echo cancellation parameters take effect only after the echo-canceler enable command is configured.
The convergence-rate value and max-amplitude value options take effect only when the cng-on
command is configured.
Examples
# Set the convergence rate of comfort noise amplitude to 50.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] echo-canceler convergence-rate 50
