WellGate 3804 User Manual
S/W version:4fxo.115
Release version,:2.4
-nscng No sound compression and CNG. (G.723.1 only, On=1, Off=0).
-echo Setting of echo canceller. (On=1, Off=0, per port basis).
-mindelay Setting of jitter buffer min delay. (0~150, default: 100).
-maxdelay Setting of jitter buffer max delay. (0~150, default: 150).
Example:
voice -send g723 60 g711a 60 g711u 60 g729a 60
voice -volume voice 20 input 32 dtmf 27
voice -echo 1 1
Parameters Usage:
-print print current voice information and configurations.
-send to define packet size for each codec. 20/40/60ms means to send
a voice packet per 20/40/60 milliseconds. The smaller the packet
size, the shorter the delay time. If network is in good condition,
smaller sending packet size is recommended. In this parameter,
20/40/60ms is applicable to G.711u/a law, and G.729a codec,
while 30/60ms is applicable to G.723.1 codec.
-priority codec priority while negotiating with other h323 device. This
parameter determines the listed sequence in h.245 TCS
message. The codec listed in left side has the highest priority
when both parties determining final codec.
-volume There are three adjustable value. voice volume stands for volume,
which can be heard from WellGate 3804 side; input gain stands
for volume, which the opposite party hears. dtmf volume stands
for DTMF volume/level, which sends to its own Line1 or Line2.
-nscng silence suppression and comfort noise generation setting (1 = ON; 0
= OFF). It is applicable to G.723 codec only. An example is
demonstrated below:
-------------------------------------------------------------------------------------------------
usr/config$ voice -nscng g723 1
-mindelay the minimum jitter buffer size. (Default value= 90 ms)
-maxdelay the minimum jitter buffer size. (Default value= 150 ms)
-------------------------------------------------------------------------------------------------
usr/config$ voice –mindelay 90 –maxdelay 150 -optfacor 7
-echo activate each canceller (1 = ON; 0 = OFF).
Note: be sure to know well the application before you change voice
parameters because this might cause incompatibility.
5.16 [tos] command
TOS service allows users to achieve QoS on IP network.
-------------------------------------------------------------------------------------------------
usr/config$ tos
IP Packet ToS(type of Service)information and configuration
Usage:
tos [-rtptype precedence]
