13.3 Real Time Jitter Control
When telephoning over the Internet, voice data packets normally have the highest priority.
Nevertheless, if the upstream bandwidth is low, noticeable delays in voice transmission can
occur when other packets are routed at the same time.
The real time jitter control function solves this problem. So that the "line" is not blocked for
too long for the voice data packets, the size of the other packets can be reduced, if re-
quired, during a telephone call.
