# System IP Ports

## Purpose

The System IP Ports form is used to associate the SIP transport protocol used with the port on the local host. If a value other than the default is used, the user should validate that the port is not being used elsewhere.

Use this form when performing the following tasks:

- SIP Trunking for Service Provider

- Program SIP Trunks

## Conditions

- If you change the System IP Port settings, the changes will take effect after the next system reboot.
