Firmware is software that runs on a device and tells it how to operate. Manufacturers often update this to fix any issues their devices might have, so it is worth doing on a regular basis to ensure your phone is up to date. If you have any problems using your device, it is often worth updating it first.
Updating the firmware of your Snom phone is a simple process that will only take a few minutes.
Please note that if you purchased your phone from Gradwell and we manage the device (i.e. you asked us to configure an extension on the unit) then we will handle firmware upgrades for you.
To start, navigate to the snom support pages. Click on your series of phone (for example, snom3x0) and then select your phone model.
Now click on the firmware link and then select which firmware version is currently installed on your phone (if you're not sure, you can check via the web interface - see below).
Select the manual update link to a newer version of firmware, and then right click your phone model and copy the URL into your clipboard. To exact wording to do this will depend on your web browser, but it will say something like "copy link address", "copy link location" or "copy shortcut".
You will now need to go to the web interface for your phone. To do this, enter the IP address of your phone into your web browser.
Click on Advanced and then Update.
Paste the URL that you copied into your clipboard into the Setting URL box (deleting any text that is in there first).
Now click Save and then Reboot. The phone will reboot itself and may ask you if you want to update the firmware. It is very important NOT to unplug the power whilst this process is taking place. Doing say may permanently damage your phone.
When the firmware update is complete your phone will restart and be ready to use again.
The video below will help walk you through this process. You can pause and rewind the video as necessary, and use it along with the notes above.
If you are unsure what version of firmware is currently on your device, you can do it via the web interface.
Enter the IP address of your phone into your web browser, and click on Status and then System Information. The current firmware version is shown in the Application-Version section, and will be after your phone device, for example if it says "snom320-SIP 6.0.5" your firmware version will be 6.0.5.
