Do you want to manually back up the configuration of your desk phone, or transfer the configuration from a phone to one or more devices of the same model, manually without a provisioning server?'

Then this is the right guide for you.

Configure the "prototype" of your phone as it should be on all phones later. This can be e.g. colors and a link to a backround picture, ringtones for incoming and outgoing numbers and of course speed dial or BLF keys. From this "prototype" you then create a "backup" and you have to shorten the backup a little bit and can then transfer it to other phones.
Dies können z.B. Farben und ein Link zu einem Hintegrrundbild sein, Klingeltöne für eingehende und ausgehende Rufnummern und natürlich Schnellwahl bzw. BLF-Tasten sein. Von diesem "Prototypen" erstellen Sie dann ein "Backup" und das Backup müssen Sie ein wenig einkürzen und können es dann auf andere Telefone überrtagen.

Back Up

Let's first look at how you can create the backup from your source device (prototype).

The following file types can be saved as backups from the phone's web user interface:

  • .cfg Config File
  • .xml XML File

The following is recommended:

  • Using the .xml format is recommended, but the CFG file works also very good.
  • Usually it's recommended and enough save the settings which have changed from default.

NOTE: Passwords will not be saved. You can manually re-enter the passwords in the settings file, or set them again directly after the phone after the restore.

If you need help to enter the Webuserinterface (WUI), please look here: Entering Snom Deskphone Web Interface - WUI

  1. Determine the IP Address of the Phone by clicking the Help Information →Information → System Info

  2. Launch a web browser and enter that IP address into the Address bar and click enter.

  3. Click the Settings link, you’ll find it located under the Status Category in the Vertical navigation links section on the left side of the web page.

  4. At the top of the Settings page you’ll have options to save the Configuration File.

  5. Click best onto the "Changed Settings (.xml)" to download only the changed configuration, except of any passwords.

    For a complete Back Up of the specific snom phone, choose "All settings".


  1. If you want to make a complete backup (All Settings) of the phone you are looking at, just continue with the instructions.
  2. If you plan to transfer the configuration of a phone (Changed settings) to one or more phones of the same type, you must revise the configuration file and remove the lines referring to the network configuration. Otherwise the phones will all be configured with the same fixed IP address, which will inevitably lead to problems. Then follow the steps of this guide.

  1. Repeat steps 1 and 2 from the Back Up Section and go to the Web User Interface for your Snom phone.

  2. Click the Advanced Link that is located in the Setup Category in the Vertical navigation links section on the left side of the WUI.

  3. Click the Update Tab on the Advanced Settings Tab Menu options.

  4. Using the "Choose File" button on the File Uploader segment of the page ("Upload Setting File manually"), locate your Back up Configuration File.

  5. Then click the Load button. Watch the LED panel on your Phone and you’ll see the Restore going on. This step will take a few minutes and when complete you’re done restoring the configuration from Backup.

  6. Last step, login and set passwords new.

Known issues when using the .cfg version

If your phone was set up with a Static IP Address it will get converted to DHCP during the restore process. This will make it appear as if the Web Page is going to time out. It’s not really timing out, but the IP Address used to manage the Phone could have been changed by the DHCP server.

At this point just watch the screen on the Phone. When the restore process reaches a point where you’re being asked to Select a Language pick up the Restore Process from the Phone and:

  1. Select a Language
  2. Choose Your Time Zone and tone scheme

At this point you have nearly fully restored the Backup Configuration File.

If you would like to revert back to your Static IP Address you’ll need to.

  1. Go into the Phone Settings on the Phone.
  2. Turn off DHCP.
  3. Re-enter your Static IP Address.
