UDP
RTP/RTCP media
36000-
59999
The range is configurable.
On S/M Expressway, the first two ports can be used for multiplexed
media if you do not use default/custom ports.
On L Expressway, the first twelve ports of the range are used for
multiplexed media. You cannot customize that subrange.
UDP
Multiplexed
media on
Small/Medium
Expressway-E
systems
2776/2777
OR
36000/36001
2776/2777 is older pair but kept as default by the ability to
customize when the new default range was introduced with
S/M system options. Custom pair is defined on
Configuration
> Traversal > Ports
.
On Expressway-E only.
Note:
In the connection maps and port references we do not show
all the port options for the sake of clarity. For example, if the
diagram shows 2776/2776, but you have chosen to use
36000/36001 instead, then you don't need to also open 2776/2777.
UDP
Multiplexed
media on Large
Expressway-E
systems
36000-
36011
New range introduced with Large system option. This range is
always the first twelve ports of the RTP/RTCP media range, so it
will be different if you configure a different media range.
On Expressway-E Large OVAs or large scale appliances only.
Note:
In the connection maps and port references we do not show
all the port options for the sake of clarity. For example, if the
diagram shows 2776/2776, but you have a large Expressway, then
you should open the first twelve ports of the media range instead of
2776/2777.
TCP
SIP traversal
7001
Configurable. SIP listening port on the first Expressway-E traversal
server zone. Subsequent traversal server zones will use incremental
port numbers, eg. 7002, by default.
UDP
H.323 traversal
6001
Configurable. H.323 listening port on the first Expressway-E
traversal server zone. Subsequent traversal server zones will use
incremental port numbers, eg. 6002, by default.
