74.9.1 Voice Parameters
The voice parameters are described in the table below.
Table 74-35: Voice Parameters
Parameter Description
Input Gain
configure voip > media voice >
input-gain
[InputGain]
Global parameter defining the pulse-code modulation (PCM) input
(received) gain control level (in decibels).
You can also configure the feature per specific calls, using IP
Profiles (IpProfile_InputGain) or Tel Profiles
(TelProfile_InputGain). For a detailed description of the parameter
and for configuring the feature, see Configuring IP Profiles on
page
404 or Configuring Tel Profiles on page 440.
Note: If the feature is configured for a specific profile, the settings
of the global parameter is ignored for calls associated with the
profile.
Voice Volume
configure voip > media voice >
voice-volume
[VoiceVolume]
Global parameter defining the voice gain control (in decibels).
This defines the level of the transmitted (IP-to-Tel) signal.
You can also configure the feature per specific calls, using IP
Profiles (IpProfile_VoiceVolume) or Tel Profiles
(TelProfile_VoiceVolume). For a detailed description of the
parameter and for configuring the feature, see Configuring IP
Profiles on page
404 or Configuring Tel Profiles on page 440.
Note: If the feature is configured for a specific profile, the settings
of the global parameter is ignored for calls associated with the
profile.
configure voip > media voice
codecs > G726-voice-payload-
format
[VoicePayloadFormat]
Determines the bit ordering of the G.726 voice payload format.

[0] = (Default) Little Endian

[1] = Big Endian
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 on page
404 or Configuring Tel Profiles on page 440.
Note: If the feature is configured for a specific profile, the settings
of this global parameter is ignored for calls associated with the
profile.
configure voip > media voice >
echo-canceller-hybrid-loss
[ECHybridLoss]
Defines the four-wire to two-wire worst-case Hybrid loss, the ratio
between the signal level sent to the hybrid and the echo level
returning from the hybrid.

[0] = (Default) 6 dB

[1] = N/A
