Jitter Buffer Configuration
You can configure the mode of jitter buffer and the delay time for jitter buffer in the wired network or wireless net-
work.
The following table lists the parameters you can use to configure the jitter buffer.
Parameter voice.jib.adaptive <y0000000000xx>.cfg
Description It configures the type of jitter buffer in the wired network.
Permitted
Values
0 -Fixed
1 -Adaptive
Default 1
Web UI Settings > Voice > Jitter Buffer > Type
Parameter voice.jib.min <y0000000000xx>.cfg
Description
It configures the minimum delay time (in milliseconds) of the jitter buffer in the wired network.
Note : It works only if “voice.jib.adaptive” is set to 1 (Adaptive). The value of this parameter should be
less than or equal to that of “voice.jib.normal”.
Permitted
Values
Integer from 0 to 400
Default 60
Web UI Settings > Voice > Jitter Buffer > Min Delay
Parameter voice.jib.max <y0000000000xx>.cfg
Description
It configures the maximum delay time (in milliseconds) of the jitter buffer in the wired network.
Note : It works only if “voice.jib.adaptive” is set to 1 (Adaptive). The value of this parameter should be
greater than or equal to that of “voice.jib.normal”.
Permitted
Values
Integer from 0 to 400
Default
240
Web UI
Settings > Voice > Jitter Buffer > Max Delay
Parameter
voice.jib.normal <y0000000000xx>.cfg
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”.
Permitted
Values
Integer from 0 to 400
Default 120
Web UI
Settings > Voice > Jitter Buffer > Normal
DTMF
DTMF (Dual Tone Multi-frequency) tone, better known as touch tone. DTMF is the signal sent from the IP phone to
the network, which is generated when pressing the IP phone’s keypad during a call. Each key pressed on the IP
phone generates one sinusoidal tone of two frequencies. One is generated from a high-frequency group and the
other from a low-frequency group.
