-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.
TOS service allows users to achieve QoS on IP network.
