You can configure the delay time for the static jitter buffer.<br \/>An adaptive jitter buffer can adjust based on the delays in the network. The range of this delay time is configurable.<\/p>\n<h6><em>Maximum Delay and Minimum Delay<\/em><\/h6>\n<p>There are two parameters are used to limit the range of the delay. When receiving a RTP packet, it will be defined as an underflow event if the packet delay is smaller than minimum, and vice versa an overflow event if it is greater than maximum.<br \/>In both cases this will cause packet loss, and lead to audio loss.<br \/>The Max delay and Min delay are used only when the Jitter Buffer is configured to be \u201cfixed\u201d.<br \/>If the Jitter Buffer is configured as adaptive, it will adjust itself accordingly base on the network latency.
