Description
It configures the normal delay time (in milliseconds) of the jitter buffer in the wired network.
Note: It works only if “voice.jib.adaptive” is set to 0 (Fixed). The value of this parameter should be
greater than or equal to that of “voice.jib.min” and less than or equal to that of “voice.jib.max”.
