CHAPTER72 Configuration Parameters Reference
Mediant 800 Gateway & E-SBC | User's Manual
Parameter Description
Note: To ensure high voice quality when using
G.726, both communicating ends should use the
same endianness format. Therefore, when the
device communicates with a third-party entity
that uses the G.726 voice coder and voice quality
is poor, change the settings of the parameter
(between Big Endian and Little Endian).
'Echo Canceler'
configure voip > media voice >
echo-canceller-enable
[EnableEchoCanceller]
Global parameter enabling echo cancellation (i.e.,
echo from voice calls is removed).
You can also configure this feature per specific
calls, using IP Profiles (IpProfile_
EnableEchoCanceller) ) or Tel Profiles
(TelProfile_EnableEC). For a detailed description
of the parameter and for configuring the feature,
see Configuring IP Profiles or Configuring Tel
Profiles.
Note: If the feature is configured for a specific
profile, the settings of this global parameter is
ignored for calls associated with the profile.
'Network Echo Suppressor Enable'
configure voip/media
voice/acoustic-echo-
suppressor-enable
[AcousticEchoSuppressorSupport]
Enables the network Acoustic Echo Suppressor
feature on SBC calls. This feature removes
echoes and sends only the near-end’s desired
speech signal to the network (i.e., to the far-end
party).
■ [0] Disable (default)
■ [1] Enable
Note: For the parameter to take effect, a device
reset is required.
'Echo Canceller Type'
configure voip/media
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.
