How to reset Snom Handsets

How can I set the phone back to admin mode or factory defaults respectively

  1. How to switch between "User Mode" and "Admin Mode"
  2. How to reset lost administrator password
  3. How to reset lost HTTP password
  4. How to reset lost administrator and HTTP password

  1. To set the phone back to "Admin mode", press the Settings key.
    1. Firmware versions lower than 7.X: Select "Admin Mode".
    2. Firmware versions lower equal or greater 7.X: Enter "Maintenance" and select "Admin Mode".
    3. On the prompt enter your administrator password, if you have set one, or the default password, which is "0000" (four zeros), and confirm.

     

  2. Reset lost administrator password by performing a reset to factory defaults (Warning: All configuration changes get lost!) via Web User Interface (Note: This will work only when the web user interface is not secured by a password):
    1. Obtain your phone's IP address and currently used firmware version by pressing the Help button on your snom 3x0
    2. Open any web browser and choose the URL corresponding to your current firmware version:
      1. Firmware versions lower than 3.X: http://phonesIpAdr/set_base_en.htm?reset=Reset
      2. Firmware versions between 3.X and 6.X: http://phonesIpAdr/advanced.htm?reset=Reset
      3. Firmware versions from 7.X onwards: http://phonesIpAdr/advanced_network.htm?reset=Reset
    3. Copy the appropriate URL into the address line of your web browser and then change "phonesIPAdr" to your phone's actual IP address.
    4. The phone reboots automatically and everything will be accessible again.

     

  3. Reset lost HTTP password via Phone User Interface:
    1. Snom 3xx series : Press the "Settings" Key and scroll down to "Reset Values". Confirm by pressing and enter the Administrator password!

     

  4. Reset lost administrator and HTTP password via TFTP Update ( Note: This process combines firmware update and factory reset)
  • Since firmware version 8.7.3.7 on the snom 3xx series it is possible to reset the phone using the key pad by pressing the following keys: * Volume Up * Volume Down #
Snoms can be "factory" reset without Admin password by holding in the # key and connecting power to the device (poe or psu) 
and continue to hold the key until the device eventually boots into "recovery" mode. This has been tested on the snom 7xx and 8xx series.
