Here you can find some special Information for D8XX Series Desk Phones


Do you want to set up and start using a Snom desk phone? On this page we would like to give you the basics and point the way to further articles for the setup of our desk phones.

Note: For the operation of a VoIP desk phone it is in most cases necessary to have a telephony server available, a so-called PBX. To a limited extent, a Fritzbox also supports such a VoIP phone as well as other providers on the market. Unfortunately, we do not support the Fritzbox and other small solutions. Which PBX system Snom supports, please refer to our PBX partner list. Fritzbox users can find a basic configuration in the following link Setting up a Snom Device on a Fritzbox.

Unpacking and connecting

In this section, we explain how to correctly wire and assemble your Snom phone after unpacking. Furthermore, we will go into the power supply of the phone.

  1.  Wiring and assembling 
    Read a short tutorial on how to wire your desk phone correctly. Assembling our phones is otherwise quite simple.

  2.  Power supply 
    You can power Snom desk phones in two different ways,

    1. One is via PoE (Power over Ethernet), which is power supplied via the network cable.

    2. via an external power source like a power supply (Snom A6) or 

    3. our PoE injector (Snom A5).

      Since we assume standard use of PoE technology, we generally do not include power supplies with our devices.

      If you want to connect your Snom desk phone using PoE, you need a network switch with PoE function and a wattage corresponding to the amount of connected phones. The required wattage can be calculated very easily. Based on the PoE class (Snom uses PoE classes 1,2 and 3) you can first determine the maximum wattage of your used phones and then simply multiply it by the number of units and you have the desired result. Which PoE class your phone has can be found in our comparison list.

      Here is an example: 1 D785 has PoE class 3, which equals 12.95 watts, rounded 13 watts. So if I have 10 x D785 this results in 10 x 13 Watt = 130 Watt.

      Please note, however, that in addition to the wattage required by the phones, you also need some power to operate the PoE switch. Usually a "net power" is indicated on the devices, or rather in the data sheets of the network PoE switches. This indicates how much power the switch can deliver. The second larger value indicates the total power including the power required by the switch.


Setup of a desk phone

To set up your phone you have three options.

  1. The first one is of course the PUI ( Phone User Interface) on the phone itself, but you can't set all things here and it's not as comfortable.
  2. The other option is the web user interface, also called WUI ( Web User Interface). Here you can configure your phone comfortably with the help of a browser.
    Read here how to get the IP address of your phone to log into the WUI.

  3. The most elegant but also most complicated option is usually used by most commercial phone systems, autoprovisioning. In this process the phone receives an XML file with all important configuration information on request. As an end customer you usually have nothing to do with this process, so there remain the first two points to customize your phone.


All settings that you make manually on your phone (WUI or PUI) and not in the web interface of the PBX can and will be overwritten by most commercial phone systems, at regular intervals, but at the latest after a reboot of the phone from the PBX. This is due to the fact that our phones act as network clients and are controlled by the server, i.e. the PBX. In any case, this note applies to most PBX systems we work with.

Making phones secure

Since Snom phones are network-enabled devices, they are subject to almost the same threats as any server or workstation computer. For this reason, we at Snom place great emphasis on security. Read here what measures you should take to make your Snom desk phone secure.

If you see error messages on your phone "No administrator password" or "No HTTP password" you are in the right place. This relates to phone security and can be fixed by following the link about this.

Connecting the phone to a PBX

Our phones use all common standards described in the usual RFCs. That's why we are compatible to most PBXs. But unfortunately there are always individual deviations with different providers, which we do not support. This and the issue of autoprovisioning (where the phone receives its configuration automatically from the PBX) require that for smooth operation you work exclusively with PBXs that are partners of Snom and where we can guarantee error-free operation to the greatest extent possible thanks to mutual testing. You can find a list of our PBX partners here.

For some PBXs we have also provided a separate manual which you can find here:

The Fritzbox is not officially supported by us, because it is a consumer product with only limited VoIP functionality. Due to the widespread use of Fritzbox in Germany, we still provide instructions for our different product groups: Setting up a Snom Device on a Fritzbox.

Firmware Update

Usually the firmware of your phone is updated automatically by the PBX of your choice. However, this varies from PBX to PBX. If you are working with a PBX that does not support this, we will show you how to do this manually in the following article.

Phone customization

D1xx, D3xx, D7xx Series

One of the fantastic new features of the firmware version 10 is the really extensive possibility to customize the desk phone individually to your wishes. It is possible to customize all colors and transparency values of the visible menus and screens, change icons and background images contextually, add, change or delete menus and even set up individual ringtones.

  1. Visual customization
  2. Custom ringtones
  3. Customize menus

D8xx Series

Reset phone (Factory Reset)

If your phone no longer does what you want it to do, e.g. after a firmware update. Or if you bought a used phone and now want to reset the phone completely, then a setting reset or factory reset is often the best option.

  1. If you bought a used phone and it still logs on with the old credentials after a simple reset or a full factory reset, then most likely the MAC address of the device was set up in our SRAPS server with a forwarding to the phone system of the previous owner. You can find out how to proceed in this case here.
  2. If a phone, when you change the PBX within your company, still logs on to the old PBX after you reset it, your DHCP server may still be configured to point to the old PBX via  options 66 & 67.

Overview of desk phone features

In early 2019, our first official firmware version 10 was released and with it a lot of new features. So if you are looking for a feature, be sure to take a look around the section.

Other connections

Connecting a headset

If you want to have your hands free while making calls, a headset is usually the best choice. The Snom company offers several cordless and corded models for this purpose. You can find an overview here.

  1. If you want to use a headset from a third party with a wireless base that is connected to our desk phones via cable, you need an EHS adapter. The A170 from Snom is such a device, but it has the EHS Adapter already built into the base. (All the usual cables are included with the A170  as with the EHS adapter.
