Table 6-56: Voice Parameters

Pulse-code modulation (PCM) input gain control (in decibels).
This parameter sets the level for the received (Tel-to-IP)
signal.
The valid range is -32 to 31 dB. The default value is 0 dB.
Voice gain control (in decibels). This parameter sets the level
for the transmitted (IP-to-Tel) signal.
The valid range is -32 to 31 dB. The default value is 0 dB.
Determines the bit ordering of the G.726/G.727 voice payload
format.
[0] = Little Endian (default)
[1] = Big Endian
Note: To ensure high voice quality when using G.726/G.727,
both communicating ends should use the same endianness
format. Therefore, when the device communicates with a third-
party entity that uses the G.726/G.727 voice coder and voice
quality is poor, change the settings of this parameter (between
Big Endian and Little Endian).
Currently, not supported.

Currently, not supported.
Determines the Answer Detector sensitivity.
The range is 0 (most sensitive) to 2 (least sensitive). The
default is 0.
Silence Suppression is a method for conserving bandwidth on
VoIP calls by not sending packets when silence is detected.
[0] Disable = Silence Suppression is disabled (default).
[1] Enable = Silence Suppression is enabled.
[2] Enable without Adaptation = A single silence packet is
sent during a silence period (applicable only to G.729).
Note: If the selected coder is G.729, the value of the 'annexb'
parameter of the fmtp attribute in the SDP is determined by
the following rules:
If EnableSilenceCompression is 0: 'annexb=no'.
If EnableSilenceCompression is 1: 'annexb=yes'.
