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 ports that you do not need in your deployment but that are enabled by default, it's highly recommended that you disable them for security reasons.

For increased security against attacks, it's highly recommended to change the default port numbers (especially for the SIP application).
