This technical note provides information on how to configure the Cisco SPA2102 (previously Linksys SPA2102) telephone adaptor for use with the Zetafax Fax Relay addon.

More information

The Cisco SPA2102 phone adaptor can be used to connect your existing physical fax machines to your Zetafax server. This will free up lines, saving on line rental, as well as integrating your existing fax machines into a centrally managed infrastructure. 

Step 1: Connecting the device.

The device comes with both an Internet and Ethernet port. We would recommend using the internet port, as the Ethernet port is enabled with DHCP by default which will affect other machines on the network.

  • Connect a fax machine or phone to the SPA2102 telephone adaptor using the port marked phone1.
  • Test for a dialtone on the line. This can be done by picking up the phone.
  • Please enter the following commands from the telephone keypad:

Enable IVR menu


Factory Reset (if the status of the unit is uincertain)


Enable web admin via WAN port


Set the WAN IP address


  • Connect to the web interface using a web browser by entering http:// followed by the WAN IP address set in the step above. For example: where was set in the stage above.
