What is a port number? | Talkswitch 48-CA/CVA, 24-CA instruction

TalkSwitch has the technology that helps keep this information up to date so that 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, the number after the colon.

Port numbers are required so that 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 that the mail can reach the correct final destination.
