Welcome

Thank you for choosing the Linksys IP Telephony System. The System combines the rich feature set of legacy PBX (Private Branch eXchange) telephone systems with the convenience and cost advantages of Internet telephony. It supports common key system features such as an auto-attendant, music-on-hold, call forwarding, three-way call conferencing, and more.

The System is so easy to configure that a fully working system can be set up in minutes. New Linksys SPA-family Internet telephones are automatically detected and registered when they are connected to the System. While the System will work with any SIP-compatible Internet telephone, it is the ideal host for Linksys business telephones, including model number: SPA941. The System supports the advanced features of these phones, such as shared line appearances, hunt groups, call transfer, call park, and group paging. Plus, with its two FXS ports, the System can support traditional analog devices such as telephones, fax machines, answering machines, media adapters.

How does the System do all of this? By connecting your analog phones or fax machines to the System and connecting the System and Internet phones to your router, then the System can direct voice communications for your network.

But what does all of this mean?

Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share Internet access, so you don’t need more than one high-speed Internet connection. With Internet phone service, your Internet access can now be shared by your Internet phones as well. You will be able to make phone calls using your Internet phone service account, even while another colleague is web browsing. Plus, you can access one printer from different computers and access data located on another computer’s hard drive (with the right permissions).

PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is why the network is called “wired”. The System takes your wired network and lets you integrate Internet phones and Internet phone service.

When you first install the System, Linksys strongly recommends that you use the Setup Wizard, which you can download from www.linksys.com. If you do not wish to run the Setup Wizard, then use the instructions in the Quick Installation or this User Guide to help you. These instructions should be all you need to get the most out of the IP Telephony System.

NOTE: Some of these features are set up from the Internet phones.

network: a series of computers or devices connected for the purpose of data sharing, storage, and/or transmission between users.

lan (local area network): the computers and networking products that make up the network in your home or office.

ethernet: an IEEE standard network protocol that specifies how data is placed on and retrieved from a common transmission medium.

What’s in this Guide?

This user guide covers the steps for setting up a network with the System. Most users will only need to use “Chapter 4: Getting Started.” When you’re finished, then you are ready to make calls within your system as well as calls to the outside world.

Chapter 2: Applications for the IP Telephony System

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 ^Internet 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

SPA941 Switch Router Desktop phone has its own extension number). Outgoing calls go to the correct external phone number (you can have more than one external phone number). ^Computer

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 ^SPA941 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 _{Analog Fax Administration} those phones to make Internet phone or fax calls. (More details are available in “Chapter 4: Getting Started.”) Phone Computer

Which Call Management Features Does the IP Telephony System Offer?

Beyond basic call routing, the System offers several powerful and sophisticated features:

• Auto-Attendant. An automated system guides each caller to the appropriate contact.
• Music-on-Hold. You can combine the auto-attendant feature with the music- or information-on-hold feature, so the caller has a richer experience with your call system.
• Call Hunt. You can designate which Internet phones receive outside calls. You can even have calls ring multiple phones, either simultaneously or one at a time.
• Paging. When you want to page all of the Internet phones, you can use the System.
• Dial Plans. When you have more than one dial plan, you can route outgoing calls to take advantage of the best rates available for the different types of calls.

After setup of the System, you will have dynamic and feature-rich Internet voice communications for your business or home.

NOTE: If your ITSP configured the System for you, then these features may already be set up. Check with your ITSP for more information.

(To set up these features yourself, refer to “Chapter 6: Using the Web-based Utility.”)

Overview

For first-time installation of the System, Linksys strongly recommends using the Setup Wizard, which you can download from www.linksys.com. For advanced users, you may follow the instructions in this chapter, and then Internet use the Web-based Utility for additional configuration (refer to “Chapter 6: Using the Web-based Utility”). To use the Interactive Voice Response Menu, proceed to “Chapter 5: Using the Interactive Voice Response Menu.”

Before You Begin

SPA941 Cable/DSL Modem Make sure you have the following:

• IP Telephony System (model number: SPA9000)
• One or more Internet phones (for example, Linksys SPA-family IP Phones, model number: SPA941)
• • A router and cable/DSL modem (or gateway) ^{SPA941 Switch Router Desktop} Computer
• One or more Ethernet network switches (so you can connect Internet phones or computers)
• NOTE: For best results, use a switch that offers QoS (Quality of Service) and full wire-speed switching. QoS enables the switch to give top priority to voice traffic, while full wire-speed _SPA941 switching lets it forward packets as fast as your network can deliver them. The next best choice is a QoS (Quality of Service) switch.
• At least one active Internet phone service account and its settings if you want to make external calls
• An active Internet connection if you want to make external calls
• At least one computer for configuration of the System and Internet phones
• Two or more Ethernet network cables
• Analog telephones or fax machines (optional)
