Home / Support / Cisco ATA Install Guide

Modified on October 10, 2021

If you purchase a second hand Cisco SPA or one that has been setup to work with a particular carrier then the safest bet is to reset the settings to the factory defaults so that you start with a clean slate and can be sure that some previously entered setting is not causing you a problem. To reset the SPA-2102 to factory defaults follow these steps:

  • Plug in power adapter
  • Plug in a phone to ‘Phone 1′ port of the SPA-2102
  • Dial ****
  • You should hear ‘Configuration Option Menu’
  • Dial 73738# (RESET#)
  • Press 1 to confirm the reset

The SPA-2102 should now have been reset to factory default settings.

You may need to do the following to set up web management depending on which interface you are coming in on:

  • Dial **** into the phone connected to the ATA device
  • You should hear ‘Configuration Option Menu’
  • Dial 7932  then press 1 to enable.
  • Hang up when you hear option saved.


  1. Get access to your SPA-2102 web interface
  • Plug in Ethernet cable to router and wait for several seconds
  • Dial ****110#
  • Listen to IP Address which is read back to you
  • Plug your PC into the LAN (Ethernet) port of the SPA-2102
  • Enter IP Address into your web browser (For example.
  • You should now see the Linksys SPA-2102 Web Interface
  1. Upgrade firmware (optional)

Your SPA-2102 may work well on it’s current firmware, but it is always a good idea to upgrade the firmware on your SPA-2102 to ensure that you are running the latest recommended firmware on it. Upgrading the firmware is relatively easy with the SPA-2102.

  • Visit
  • Click on Downloads
  • Select VoIP Routers from drop down menu under the VoIP category
  • Select SPA-2102 from the drop down menu under the picture that looks like your SPA-2102 (centre, middle)
  • Select Version 1.0
  • Click on firmware to download the Firmware ZIP file  (e.g. SPA-2102-5-2-5.ZIP)
  • Open the ZIP file in a ZIP utility such as WinZip
  • Click Extract and extract your files to a folder you choose (e.g. C:\SPA2102)
  • Use Windows Explorer to open a window on your selected folder
  • Click on the .exe Application (named something like upg-spa2102-5-2-5.exe)
  • Accept the warning and Click Continue
  • Enter the IP Address of the SPA2102 above into the Window and click OK
  • Click Upgrade to update your SPA2102 firmware to the new version you have downloaded
  • Wait until the progress indicator has finished doing the upgrade. Do NOT unplug your SPA2102 during the upgrade.
  • When successfully upgraded you should see a message like ‘Your SPA has been successfully upgraded to the version shown below’ (Latest version at time of writing was 5.2.5)
  • Now in your web browser put in the SPA-2102 IP Address again and on the Info page you should see the new firmware version displayed beside ‘Software Version’
  1. Changing your System Settings
  • Click on the ‘System’ tab
  • It is recommended you set a User and Admin password on the web interface of the SPA2102 to avoid unauthorised access.
  • Set ‘Admin Passwd’ and ‘User Password’ to a password of your choosing and write it down so you don’t forget it.
  • Click ‘Save Settings’

  • Enter ‘admin’ as the username and your new password to access your SPA2102

  • Change the following SIP Timer Values:
    • Reg Max Expires = 600
    • Reg Retry Intvl = 10

User 1/User 2 page

Most of the settings on this page are up to the customer and whether they wish to support call waiting,caller ID etc.  However we recommend the following settings be applied:

  • Block CID Setting: no    (This must be set to ‘no’ otherwise you will experience problems calling out)
  • CW Setting: yes   (You should use the kiwivoip Call Waiting setting to control this feature)
  • DND Setting:  no   (You should use the kiwivoip Do Not Disturb setting to control this feature)

Troubleshooting Tips

If you are still having problems getting your SPA-2102 to register with kiwivoip then you can try disabling or enabling the STUN settings.

Another thing you can try is changing your SIP Port from ‘5060′ to ‘50600 (and 5061 to 50610 on line 2 if required)′ in the SIP Settings under each line and change the ‘Proxy’ and ‘Outbound Proxy’ from ‘’ to ‘′ in the Proxy and Registration settings under each line
