Item No. Item Input Data Default
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.
1 = static
3 = adaptive immediately

18 Silence Compression (VAD) Threshold
Set the voice level judged to be silence.
Change value based .30
This entry is ignored if silence compression is disabled
in 84-01-03 with G.711 or 84-01-06 with G.729.

28 Priority Codec Setting
The option selected here determines what other codec
options are applied by priority.
For the system to utilize the G.723 or iLBC Codecs,
program 84-27-02 must be set to G.723/iLBC.
0=G.711PT
1 = G.723 PT
2 = G.729 PT
3=G.722
4=G.726
5=iLBC

30 EchoAuto Gain Control
Define the Auto Gain Control.
0~5 0
31 DTMF Payload Number
Define the DTMF Payload Number.
96 ~ 127 96
32 DTMF Relay Mode
Determine the DTMF setup used between the SIP ex-
tensions. It is effective when a terminal call is made
through the VoIPDB.
0=Disable
1 = RFC2833

33 G.722 Audio Frame
Maximum number of G.722 Audio Frames. G.722 as-
sumes the audio signal made by a specimen by 16
kHz and the frame of 10 ms is assumed to be a unit to
64 kbps by the encoding compressed method.
1=10ms
2=20ms
3=30ms
4=40ms

35 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 ab-
sorbed.
0 ~ 255 ms 30
36 G.722 Jitter Buffer - Standard
Set the average G.722 Jitter Buffer.
0 ~ 255 ms 60
37 G.722 Jitter Buffer - Maximum
Set the maximum G.722 Jitter Buffer.
0 ~ 255 ms 120
38 G.726 Audio Frame
Maximum number of G.726 Audio Frames. G.726 as-
sumes the audio signal made by a specimen by 16
kHz and the frame of 10 ms is assumed to be a unit to
32 kbps by the encoding compressed method.
1=10ms
2=20ms
3=30ms
4=40ms

39 G.726 Silence Compression (VAD) Mode
Select whether to compress silence with G.726. When
there is silence, the RTP packet is not sent.
0=Disable
1 = Enable
0
40 G.726 Jitter Buffer - Minimum
Set the minimum value of the Jitter Buffer of G.726 is
set. Jitter is the variation in the time between packets
arriving and the buffer allows this variation to be ab-
sorbed.
0 ~ 255 ms 30
41 G.726 Jitter Buffer - Standard
Set the average G.726 Jitter Buffer.
0 ~ 255 ms 60
42 G.726 Jitter Buffer - Maximum
Set the maximum G.726 Jitter Buffer.
0 ~ 255 ms 120
43 iLBC Audio Frame
Maximum number of iLBC Audio Frames. iLBC as-
sumes the frame of 10ms is a unit.
2=20ms
3=30ms
4=40ms
