09 G.729 Jitter Buffer - Minimum
Set the minimum value of the Jitter Buffer of G.729 is set.
Jitter is the variation in the time between packets arriving
and the buffer allows this variation to be absorbed.
10 G.729 Jitter Buffer - Standard
Set the average G.729 Jitter Buffer.
11 G.729 Jitter Buffer - Maximum
Set the maximum G.729 Jitter Buffer.
17 Jitter Buffer Mode Set the mode of the Jitter Buffer.
1 = Size set to the fixed amount for the codec.
2 = The minimum/maximum range for the codec is used.
3 = The minimum/maximum range for the codec is used
and adjust at any time, regardless of silence.
18 Silence Compression (VAD) Threshold
Set the voice level judged to be silence. Change value
based .30

options are applied by priority.
30 EchoAuto Gain Control

31 DTMF Payload Number
32 G.722 Audio Frame
Maximum number of G.722 Audio Frames. G.722 as-
sumes the audio signal made by a specimen by 16kHz
and the frame of 10ms is assumed to be a unit to 64kbps
by the encoding compressed method.
The Audio frame size setting is only from IP phone to IP
phone. When the IP phone communicates to a TDM de-
vice it will always use a 20 ms frame size.
Softphone (SP310) only supports 20 ms.
34 G.722 Jitter Buffer - Minimum
Set the minimum value of the Jitter Buffer of G.722 is set.
Jitter is the variation in the time between packets arriving
and the buffer allows this variation to be absorbed.
35 G.722 Jitter Buffer - Standard
Set the average G.722 Jitter Buffer.
36 G.722 Jitter Buffer - Maximum
