Introduction

To be clear, a FritzBox can easily act as a SIP registrar and thus integrate VoIP phones just like ISDN or analog phones used to. However, the range of functions of the FritzBox is unfortunately not comparable with that of a professional telephone system (PBX).


This article is based on a test on a FritzBox 7390. It was tested on a Telekom All-IP connection.

If you want to connect a new Fritzbox to a Snom phone and need help setting up the Internet access, you can find a small guide in this article.



Overview

The configuration of a Snom device on the FritzBox is relatively simple. First you have to create a new telephony device in the FritzBox - type is IP phone.

The user name and password are important here.

  • The user name should have at least 8 characters.
  • AVM changed the password rules. Now it has to be more safe. And it is no longer important how long it is, but i should have a combination of lower and upper case letters, numbers and special characters as usual. (Tested on a Fritzbox 7590 - FW Version 07.12)



    Older Entry from 2018: The password must have exactly 8 characters, no more and no less.)

You should only allow registration from the Internet if you really need it. This is not necessary for an IP phone behind the Fritz Box and should therefore remain deactivated for security reasons.


Step by step guide - FritzBox

  • Click on "Telephony" in the menu on the left and select "Telephony device".
  • Click on the far right point: "Set up new device".



  • Since the desired telephone (with and without answering machine) is already selected by default, simply click on "Next" on the far right here.



  • Next select the item: "LAN/WAN (IP phone)".
  • Name the new phone with a unique name.
  • Then click on "Next" again.



  • Now assign a "user name" and a "password". (The assigned phone number can also be used as user name if you want.)
  • Then click on "Next".
  • The user name should have at least 8 characters.
  • AVM changed the password rules. Now it has to be more safe. And it is no longer important how long it is, but i should have a combination of lower and upper case letters, numbers and special characters as usual. (Tested on a Fritzbox 7590 - FW Version 07.12)


    Older Entry from 2018: The password must have exactly 8 characters, no more and no less.)




  • Select the phone number you want to use for outgoing calls.
  • Then click on "Next"



  • Now select the phone number under which the new telephone is to be reached (usually the same phone number as the outgoing number).
  • Then click on "Next"



  • Check in the summary if everything looks correct.
  • Then click on "Next".



  • To complete the process, a "popup window" will appear asking you to do this with an existing telephone 
    to confirm the legality of the setup process. This prevents external users from misusing your FritzBox for their own purposes.
  • If you don't have another phone just press the FritzBox button on your FritzBox. (See link in popup window).



  • Once the process has been successfully completed, you will receive another "Popup Window" as confirmation.



  • After successful setup, the new Snom Phone should now be available under "Telephony Devices", and can be configured there at any time. 



Step by step guide - Snom C520 WiMi

With the setup of the Fritzbox, most of the setup is done. Now you only have to set up the C520 WiMi.

Enter Snom C520 WiMi - Webinterface
  • To access the device, enter the IP address of your C520 WiMi into your Internet browser (e.g. http://192.168.1.100). To find out the IP address of your C520 WiMi, press the configuration key (gear icon) → "Status" → "Network". Confirm each with the checkmark icon.

  • The default access data are:
    • user / user
    • admin / admin
  • Please note that you should change the admin password directly during the setup ATTENTION: Do not forget the password, otherwise you will not be able to access your configuration.


Under "System/User Preferences" you can set the web interface to French and Spanish in addition to English, and the telephone language to German.

Until you have configured a Sip identity / extension, the three lamps around the speaker in the center will flash continuously. As soon as the extension is registered correctly, the lamps turn off immediately.

Configure Snom Identity

  • First select the menu item "System" at the top and then the item "Account1" on the left side and enter the access data you assigned in the FritzBox at "Authentication Name" and "Authentication Password".

  • Add a display name to the configuration, which you enter at "Account Label".

  • At "SIP Server/Server Address" & "Registration/Server Address" enter "fritz.box" or even better the IP address of your FritzBox.

  • Don't forget to activate the extension by checking "Enable Account" above.

  • If you now click the "save" button at the bottom, your Snom device should work immediately and the yellow LEDs should stop blinking.

  • The basic setup is now complete.

  • You can of course still change things like the ringtone, or the phone / web interface language under the menu item: "System/User Preferences".

    By default, the C520 WiMi and web interface language is in English and can only be changed to French or Spanish.
