Inbound TURN requests on Large Expressway-E
|
3478-3483

RTP/RTCP media
|
36000-59999
|
The range is configurable within the default bounds. E.g., 37000-38200, but not 35000-36200.
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.

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 .
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 2776/2777, 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 2776/2777, but you have a large Expressway, then you should open the first twelve ports of the media range instead
of 2776/2777.

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.

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.
