Table 60-34: Voice Parameters
Global parameter defining the pulse-code modulation
(PCM) input (received) gain control level (in decibels).
You can also configure the functionality per specific calls,
using IP Profiles (IpProfile_InputGain). For a detailed
description of the parameter and for configuring the
functionality, see ''Configuring IP Profiles'' on page 418.
Note: If the functionality is configured for a specific profile,
the settings of the global parameter is ignored for calls
associated with the profile.
Global parameter defining the voice gain control (in
decibels). This defines the level of the transmitted signal.
You can also configure the functionality per specific calls,
using IP Profiles (IpProfile_VoiceVolume). For a detailed
description of the parameter and for configuring the
functionality, see ''Configuring IP Profiles'' on page 418.
Note: If the functionality is configured for a specific profile,
the settings of the global parameter is ignored for calls
associated with the profile.
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).
Global parameter enabling echo cancellation (i.e., echo
from voice calls is removed).
You can also configure this functionality per specific calls,
using IP Profiles (IpProfile_EnableEchoCanceller). For a
detailed description of the parameter and for configuring
the functionality, see ''Configuring IP Profiles'' on page 418.
Note: If the functionality is configured for a specific profile,
the settings of this global parameter is ignored for calls
associated with the profile.
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
