Frequently Asked Questions

How do I make a phone call?

For calls within your system, pick up your phone and dial the extension number you want. For external calls, follow the instructions of your ITSP. You may be asked to dial a specific prefix for outside calls. For more information, contact your ITSP.

Can I make calls if my Internet connection is down?

When you make Internet phone calls, your high-speed Internet connection must be active. However, if you have maintained a traditional analog phone account, then you can still make calls through the Linksys Analog Telephone Adapter (model number: SPA3000); refer to the SPA3000 documentation for more information.

How do I access my voicemail?

Voicemail is handled by your ITSP. Contact your provider for more information.

How do I check which Internet phones have registered with the System?

Open the web browser on a networked computer. Enter http://192.168.0.1/admin/voice/status. The PBX

Status screen lists the Internet phones that have registered with the System.

What is the maximum number of IP addresses that the System will support?

The System will support up to 253 IP addresses.

Does the System support IPX or AppleTalk?

No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications. IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk, a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but those protocols cannot connect from the Internet to the LAN.

What is Network Address Translation and what is it used for?

Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is never transmitted on the Internet. Furthermore, NAT allows the System to be used with low-cost Internet accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may have many private addresses behind this single address provided by the ISP.

Does the System support any operating system other than Windows 98, Millennium, 2000, or XP? Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of any non-Windows operating systems.
