SPA9x2 Phone Field Reference

Ext Tab

Parameter	Description
Network Jitter Level	Determines how jitter buffer size is adjusted by the
	SPA9x2. Jitter buffer size is adjusted dynamically. The
	minimum jitter buffer size is 30 milliseconds or (10
	milliseconds + current RTP frame size), whichever is
	larger, for all jitter level settings. However, the starting
	jitter buffer size value is larger for higher jitter levels. This
	setting controls the rate at which the jitter buffer size is
	adjusted to reach the minimum. Select the appropriate
	setting: low, medium, high, very high, or extremely high.
	Defaults to high.
Jitter Buffer Adjustment	Controls how the jitter buffer should be adjusted. Select
	the appropriate setting: up and down, up only, down
	only, or disable.
	Defaults to up and down.
