Description Use the vqa dscp command to globally set the DSCP subfield in the ToS field in IP
packets that carry the RTP stream or voice signaling.
Use the
undo dscp media command to restore the default.
By default, the DSCP subfield is set to ef, namely, 101110.

The function of this command is the same as the command used for setting DSCP
in the “QoS” part of this manual. If two DSCP values are configured, the one
configured in the “QoS” part takes priority.
Example # Set the DSCP value in the ToS field in the IP packets that carry voice signaling to
af41.
<Sysname> system-view
[Sysname] voice-setup
[Sysname-voice] vqa dscp signal af41

Parameter buffer-time time: Duration in milliseconds of monitoring DSP buffer data, in the
range 180 to 480.
Description Use the
vqa dsp-monitor buffer-time command to set duration of monitoring
DSP buffered data.
Use the
undo vqa dsp-monitor buffer-time command to remove the setting.
By default, DSP buffered data is not monitored.
Duration greater than 240 milliseconds is recommended because too small a
duration value will result in poor voice quality in the case of severe jitter.
