Syntax
echo-canceller parameter { convergence-rate value | max-amplitude value | mix-proportion-ratio
value | talk-threshold value }
undo echo-canceller parameter { convergence-rate | max-amplitude | mix-proportion-ratio |
talk-threshold }
Default
The convergence rate of comfort noise amplitude is 0, the maximum amplitude of comfort noise is 256,
the comfort noise mixture proportion control factor is 100, and the threshold of two-way talk is 1.

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
higher the value, the greater the maximum 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
3,000 and defaults to 100. 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.
Examples
# Set the convergence rate of comfort noise amplitude to 50.
