No Parameter Description Default
06 SILENCE SUP This parameter determines whether silence suppression
is used. This prevents transmission during the silence
period of a call, and conserves bandwidth when
enabled.
DISABLE
07 TO RTP GAIN PCM input gain value of DSP. Direction is from PCM to
Packet. The range is 18~38 (-14 dB ~ +6 dB)
This set the quality of PCM voice from the VoIP DSP to
the site. Default is 32 (0 dB).
32 (0 dB)
08 TO PCM GAIN This value selects the voice volume. Direction is from
Packet to PCM. The range is 18~38 (-14 dB ~ +6 dB)
32 (0 dB).
09 MIN JITTER Decides the minimum time to consider delay for jitter
adjustment.
The range is 0~150 ms
30 ms
10 MAX JITTER Decides the maximum time to consider delay for jitter
adjustment.
The range is 30~200 ms.
150 ms
11 JITTER AP The Adaptation Period controls the speed at which the
jitter buffer can adapt downwards when current
network conditions allow. The larger the value, the
slower the jitter buffer adapts down, when jitter
decreases. The value is programmed in milliseconds,
with a default of 10000ms (10seconds) and a
minimum value of 1000ms (1 second).
1 sec
12 JITTER AT When the jitter buffer grows past the Deletion
Threshold, frames exceeding the deletion threshold are
deleted immediately. Audio quality may be negatively
affected. This parameter is expressed in
milliseconds, and may be programmed from the value
of the DelayMax up to 500ms.
The range is 150 ms~500 ms.
250 ms
13 T38 FAX USE This option selects the mode of FoIP. If selct Enable, fax
protocol is T.38. In other case, fax protocal is G.711
pass through. (This mode should be use G.711 codec)
Enable
14 T38 REDUND. This option selects retry count of Fax-over-IP if errors
are detected. The range is 0~3 (0 means no retry).
3
15 FAX ECM This option selects retry of Fax-over-IP if errors are
detected.
ENABLE
16 MAX FAX CNT This is the maximum number of channels that can be
simultaneously used for Fax-over-IP. The range is
00~04.

17 RTCP PERIOD This option selects the interval time for sending RTCP. 5 sec
