How often will my public IP address change?

This depends on the policies of your Internet Service Provider (ISP, the company that provides
your Internet access). It can be a matter of days, weeks or even months before your IP address
changes. A power loss or reboot to your cable or DSL modem usually results in the assignment of
a new IP address.
TalkSwitch has technology that helps keep this information up to date so the system can
function properly after an IP address change has been detected and updated.

What is a port number?

In an IP address like 64.26.209.103:5060, the port number is 5060; it is the number after
the colon.
Port numbers are required so a computer or device can support multiple applications or streams
of simultaneous data communication. Each stream or application uses a unique port number.
You can think of it like mailing a letter to a friend in an apartment building at a specific
address. You need to specify the apartment number as well as the address of the building, so the
mail can reach the correct final destination.
