8Connect Telephone, Fax Machine, or Modem

If you have a Cisco 803 or Cisco 804 router, you can connect a touch-tone telephone, fax machine, or modem. Use the cables provided with these devices.

The gray PHONE 1 and PHONE 2 ports are RJ-11 connectors. If you are outside of North America, you must buy and attach adapters that allow your telephones, faxes, or modems to be connected to these RJ-11 connectors. In some countries, these adapters need additional electronics to convert the telephones, faxes, or modems to work properly with the router phone ports. For example, in the United Kingdom, you must buy an adapter that also provides a master socket, which causes incoming calls to ring the connected devices. For information on recommended master sockets, see the Cisco 800 Series Routers Hardware Installation Guide.

Caution Do not connect the router telephone ports to the telephone wall jack. These ports are not meant for direct connection to the public network. This connection can damage your router.
