9.5.3 Considerations when Setting the Delay for Static Jitter Buffers
The lower the settings for average and maximum delay values, the lower the distortion factor,
especially for voice transmissions. However, these settings increase the risk of packet loss.
When the delay values are set higher, fewer packets are lost but the distortion factor increases.
The following illustration shows this relationship:
The HG board is set by default to average values that have been proven in most environments.
Measured time
maximum delay (adjustable)
Legend:

Lower delay values:
low voice distortion but individual packets are lost

Higher delay values:
higher voice distortion but lower packet loss
