84-12-17 Jitter Buffer Mode
If the jitter buffer is set to adaptive, the buffer is
adjusted (larger/smaller), depending upon
network conditions.
If the jitter buffer is set to static, it will never adjust
and always have the same size buffer.
84-12-18 Voice Activity Detection Threshold
This program is used to set the threshold of the db
level that the system uses to determine silence. If
VAD is enabled and this threshold is reached, the
system will stop transmitting "silence packets"
across the network.
84-12-33 G.722 Audio Frame Size
Assign the G.722 Audio Frame Size
The smaller the packet sizes the more bandwidth
that is consumed. However when a smaller
packet is lost in a network a smaller amount of the
voice is lost with it.
84-12-35 G.722 Minimum Jitter Buffer size
This program assigns the minimum size that the
jitter buffer will use.
84-12-36 G.722 Average Jitter Buffer size
This program assigns the average size that the
jitter buffer will use.
84-12-37 G.722 Maximum Jitter Buffer size
This program assigns the maximum size that the
jitter buffer will use.
