How Does the IP Telephony System Fit into My Business or Home?

High-speed Internet access is a valuable resource. When you have more than one computer, chances are you want to share that Internet access with all of your computers. That’s when you create a network, a collection of devices connected to each other. A device called a router connects computers and other devices, so they can share a high-speed Internet connection and other resources, including data and printers.

One of the biggest benefits of the Internet is data communications, either e-mail or web browsing, whether you send a file to a client or download the latest software upgrade. With the System, you also get voice communications.

What Does the IP Telephony System Do?

The System connects multiple Internet phones to an Internet phone service. The System manages and routes all calls. Incoming calls go to the auto-attendant, an automated greeting system, or correct internal extension (each phone has its own extension number). Outgoing calls go to the correct external phone number (you can have more than one external phone number).

You can have not only more than one external phone number, but also up to four Internet Telephony Service Providers (ITSPs) for maximum flexibility.

NOTE: The basic configuration of the System lets you connect up to four Internet phones and use up to four ITSPs. To expand the basic configuration, contact your primary ITSP for more information.

A Typical Scenario

Typically, you connect the Internet port of the System to a local network port of your router. Then connect a switch to another local network port of your router. Use this switch to connect Internet phones, computers, and other devices. Then connect an administration computer to the Ethernet port of the System.

If you have analog telephones or fax machines, you can connect them to the Phone ports, so you can also use those phones to make Internet phone or fax calls. (More details are available in “Chapter 4: Getting Started.”)
