Chapter 4 - Operation
The UDP Port Ranges menu includes the following options:
UDP RTP/RTCP Prioritization: Voice over IP is transported using Real Time

Protocol (RTP). The Real Time Control Protocol (RTCP) is used to control the
RTP. When an application uses RTP/RTCP, it chooses for destination ports
consecutive numbers: RTP port is always an even number, and the port with
the odd number following it will be assigned to RTCP.
If the administrator selects to prioritize only the RTP packets, then all the
packets with an odd numbered destination port will always have Low priority.
The packets with an even number for destination port will receive High
priority, if the port number is included in the specified ranges.
If the administrator selects to prioritize both RTP and RTCP packets, then all
packets whose destination port number is included is in the specified ranges
will receive High priority.
The available options are:

»
The default is RTP & RTCP
Add UDP Port Ranges: This option enables adding UDP port ranges to the list

of priority port numbers. The list can include up to 64 ranges. It is possible to
add discrete port numbers and/or ranges. In ranges, a hyphen is used to
separate between start and end port numbers. A comma is used to separate
entries. For example: 8900,9000-9005,9010,9016-9017.
Delete UDP Port Ranges: This option enables deleting UDP port ranges from

the list of priority port numbers. It is possible to delete discrete port numbers
and/or ranges. In ranges, a hyphen is used to separate between start and end
port numbers. A comma should be used to separate between entries.
For example: 8900,9000-9005,9010,9016-9017.
Delete All UDP Port Ranges: This option enables deleting all UDP port ranges

from the list of priority port numbers.
