Command Reference
vqa jitter-buffer
Purpose Use the vqa jitter-buffer command to configure jitter buffer depth.
Use the vqa jitter-buffer command to restore the default jitter buffer depth.
Syntax vqa jitter-buffer depth
undo vqa jitter-buffer
Parameters depth
Identify the jitter buffer depth. Valid values are 0 to 10.
Setting jitter buffer depth to 0 indicates not to enable
the jitter buffer function. The larger the value, the
larger the depth, that is, the more complexly the jitter
buffer processes the voice packets.
If no value is specified, the default jitter buffer depth is
3.
Example Configure the depth of jitter buffer as 5.

Description For networks of different performances, the depth for jitter buffer to provide the best
performance is different. Therefore the jitter buffer depth must be selected based on
a long-term observing and attempts, and in depth analysis of the actual network
situations. So that the reasonable value fitting to the network requirements can be
selected. If the depth value is too small, the jitter buffer function cannot provide the
best loss compensation, disorder adjustment, jitter removing and re-discarding
processing. If the depth value is too large, the delay will become influential to the
receiving voice gateway.
