voice/echo-canceller-type
[EchoCancellerType]
Defines the echo canceller type.
■ [0] Line echo canceller = (Default) Echo
canceller for Tel side.
■ [1] Acoustic Echo suppressor - network =
Echo canceller for IP side.
'Attenuation Intensity'
configure voip/media
voice/acoustic-echo-
suppressor-attenuation-
intensity
[AcousticEchoSuppAttenuationIntensity]
Defines the acoustic echo suppressor signals
identified as echo attenuation intensity.
The valid range is 0 to 3. The default is 0.
'Max ERL Threshold - DB'
configure voip/media
voice/acoustic-echo-
suppressor-max-ERL
[AcousticEchoSuppMaxERLThreshold]
Defines the acoustic echo suppressor maximum
ratio between signal level and returned echo from
the phone (in decibels).
The valid range is 0 to 60. The default is 10.

reference delay (in 10-ms units).
The valid range is 0 to 40. The default is 40 (i.e.,
40 x 10 = 400 ms).
