Network Port Assignment

The following table lists the device's network port assignments. This table also shows whether these ports are enabled or disabled by default and how to configure them.

For enhanced security, it's highly recommended to:

● Disable any default-enabled ports that are not required for your deployment.
● Change the default port numbers for required services (especially for the SIP application).
