In voice view, the vqa dscp media command has global significance, and the
dscp media command is valid only for the configured voice entity..
When a card is reset, all traffic carried by it will be interrupted and the card will be
re-initiated. As a general rule, you can reset a voice card when it works abnormally
(for example, the configuration is correct but the call connection cannot be
established normally). You can observe the status of the LED on the card to judge
whether a reset is performed.

For each voice entity, if the certain command is not performed to configure a
parameter, the system uses the default value of the parameter.
When there are too many voice entities on one router and the values of most voice
entity parameters are the same as the default values, the default values can be
adopted to improve the efficiency.
In some cases when the manually configured parameter values of most voice
entities are almost the same but different from the default values, to specify
suitable voice parameters for these voice entities one by one will waste much time.
In this case, you can use the default command to generate new default values
globally. In this way, each voice entity will directly inherit new default values, a
more flexible, simple and convenient configuration is thus realized.
