When jitter is 200 msec, the jitter buffer will quickly adapt up to 200 ms
(maximum). If network jitter decrease to 10msec and stays there for a LONG
time, the jitter buffer will slowly adapt down to 20 msec(minimum), and stay
there until the jitter increase to 500 msec. If network jitter decrease to 10 msec
for just a little while and goes up again, the jitter buffer may just adapt down
for a little and go up again, or may not even adapt down. For 500 msec jitter,
the jitter buffer will not go over 200 msec(maximum).
