This section shows how to configure voice settings.
3.7.1 Configuring Jitter Buffer
This section shows how to configure Jitter Buffer using the Web interface or the
configuration file.
 To define jitter buffer parameters:
1. Access the Voice page (Configuration tab > Voice Over IP menu > Voice).
Figure 3-12: Web Interface – Jitter Buffer
2. Configure the Jitter Buffer parameters according to the table below, and then click
Submit.
 Using the configuration file:
Table 3-11: Jitter Buffer Parameters
Parameter
Description
Minimum Delay
[voip/audio/jitter_buffer/min
_delay]
The initial and minimal delay of the adaptive jitter buffer
mechanism, which compensates for network problems. The
value should be set according to the expected average jitter in
the network (in milliseconds).
The valid range is 10 to 150. The default value is 35.
Optimization Factor
[voip/audio/jitter_buffer/opti
mization_factor]
The adaptation rate of the jitter buffer mechanism. Higher values
cause the jitter buffer to respond faster to increased network
jitter.
The valid range is 0 to 13. The default value is 7.
