Port Usage
The pages under the Maintenance > Tools > Port usage menu show, in table format, all the IP ports that have been
configured on the Expressway.

The information shown on these pages is specific to that particular Expressway and varies depending on the
Expressway's configuration, the option keys that have been installed and the features that have been enabled.

The information can be sorted according to any of the columns on the page, so for example you can sort the list by IP

Each page contains an Export to CSV option. This lets you save the information in a CSV (comma separated values)

Note that IP ports cannot be configured separately for IPv4 and IPv6 addresses, nor for each of the two LAN
interfaces. In other words, after an IP port has been configured for a particular service, for example SIP UDP, this will
apply to all IP addresses of that service on the Expressway. Because the tables on these pages list all IP ports and all
IP addresses, a single IP port may appear on the list up to 4 times, depending on your Expressway configuration.
