-print Display voice codec information and configuration.
-send Specify sending packet size.
G.723 (30/60 ms)
G.711U (20/40/60 ms)
G.711A (20/40/60 ms)
G.729 (20/40/60/80 ms)
-priority Priority preference of installed codecs.

-volume Specify the following levels:
voice volume (0~63, default: 25),
input gain (0~38, default: 25),
dtmf volume (0~31, default: 23),
-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: 90).

To define packet size for each codec. 20/40/60/80 ms means to
send a voice packet per 20/40/60/80 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, 20/40/60ms
is applicable to G.729 codec, while 30/60ms is applicable to
G.723.1 codec.
