If you are experiencing performance issues with your Snom 320 telephone or you lost a password and need a new one, the Snom 320 comes with several options you can use to try to solve these issues. One option is performing a simple reboot of the phone, which resets the phone without undoing any changes you made. There is also the option of performing a factory reset, which can be used to both try and solve performance issues and to reset the administrator password. You can also reset your HTTP password, if you need to, as long as you know your administrator password.

Skill level:
Moderately Easy



  1. 1

    Press the "Settings" key on the keypad.

  2. 2

    Use the left or right arrow keys on the keypad to navigate to "Configuration," then select the "Reboot" option by pressing the "S3" key.

  3. 3

    Press the check mark key to confirm the reboot of the phone.

    Factory Reset

  1. 1

    Press the "Help" button to bring up both your phone's IP address and the firmware version. Write these numbers down.

  2. 2

    Open the phone's web browser. If your phone's firmware version is lower than 3.0, enter "http://phonesIpAdr/set_base_en.htm?reset=Reset" in your web browser, where "phonesIpAdr" is the IP address you found earlier. If your phone's firmware version is 3.0 or above, enter "http://phonesIpAdr/advanced.htm?reset=Reset" in your browser, where "phonesIpAdr" is the IP address you found earlier.

  3. 3

    Wait as the phone automatically resets. The phone is finished resetting when it is back to its normal state.

    Reset HTTP Password

  1. 1

    Press the "Settings" key on the phone's keypad.

  2. 2

    Press the soft key on the keypad below where "Reset" appears on the display.

  3. 3

    Enter the administrator password when prompted. Enter in a new HTTP password.

Tips and warnings

  • Only attempt a factory reset if simply rebooting the phone does not work, since a factory reset reverts the phone back to factory settings, undoing all of the changes that you made to the phone.
