Snom IP Phone with AlphaCom XE server

This article describes how to set up Snom IP phones, models 820, 821 and 760, to operate with an AlphaCom server. The Snom Phones can be used for audio only, or they can also be used to show the video image from a Stentofon IP Video Door Station or from an external Axis camera.

For video the following possibilities can be realized:

  • Pop up video image. The video image of IP Video Door Station is shown automatically on an incoming call and end automatically when the communication is finished.
  • Manual video image. The video image of the IP Video Door Station can be activated and ended by pressing a function key.

AlphaCom configuration

The Snom phone must be configured as a SIP User in AlphaPro, Users & Stations. See article SIP phone as station for details.

Configuration of the Snom Phone

Network settings and SIP account in Snom phone

Factory default of the phone is done from the phones keyboard by pressing:

  • The button Menu
  • 5 - Maintenance
  • 4 - Reset Values
  • Enter default password 0000 + #. The phone will restart.

Follow the display setup wizard to set:

  • Language
  • Time Zone
  • Tone scheme
  • SIP Account = Directory number in AlphaCom
  • Registrar = IP address of AlphaCom
  • Select DHCP or enter IP settings of phone

The phone must be rebooted after this.

SIP account settings can be changed in Identity 1 in web access. IP settings are changed in Advanced -> Network.

Codec settings

Codec must be changed to G.711u-law (pcmu) and the internal "telphone event".

In Identity 1 -> RTP, set the codec to: "pcmu,telephone-event", remove all other codecs:

Set the codec to: "pcmu,telephone-event"

Disable Filter Packets from Registrar:

In Identity 1 -> SIP, set Support broken Registrar to "On":

Set Support broken Registrar to: "On"

Door Opening feature (optional)

During conversation with the Door Station a relay can be operated by pressing digit 6 on the Snom phone. The Snom phone uses DTMF by RFC2833 by default, which is supported by AlphaCom, so no settings are required in the phone.

In AlphaCom the relay must be mapped to a logical RCO, and an "Door Opening" event created to trigger this RCO. See Door opening for more details.

Configuration for Video

The Snom phones can be configured to show video image from the following stations/cameras:

Pop up video image

The screen of the Snom IP phone can be used to automatically show the video image during a call. The directory number of the station must be defined in the Directory of the Snom phone. When a call is made or received, the telephone will look up in the Directory, and find the correct URL for the associated camera.

In the web interface of the phone, select Directory in the menu, and enter the following parameters:

  • Number: The directory number of the IP Video Door Station, as entered in AlphaPro, Users & Stations.
  • Title: Enter any text
  • Action URL: Which URL to use depends on the type of camera/IP Station being used:
  • Nickname: Enter any text

Configure the IP Video Door station in the Directory list of the Snom phone

http://<IP address of the camera>:<mjpeg port>/snoma.cgi. For example

Manual video image

The video image can be started and ended manually by pressing a function key. With this feature the video image can be displayed without setting up a conversation.

In the web interface of the phone, select Function Keys in the menu, and enter the following parameters:

Pressing function key 1 will start the video image from camera

  • Start video image by pressing the programmed key.
  • End video image by pressing the "X-key".


If the access of the CP-CAM camera is to be password protected, the following adjustments are necessary to the URL:

  • http://<User name>:<Password>@<IP adress of the camera>/snoma.cgi. If for example username is "admin" and the password is "1234", enter http://admin:1234@

Axis camera - Uploading .XML file

When the Snom Phone is used to show an image from an Axis camera, an .xml file must be uploaded to the camera. This is applicable for IP Video Door Station model 1401110200 as well as when using standalone Axis camera.

  • Create a new textfile on your windows desktop and rename it to snomaxis.xml.
  • Open the file with a text editor e.g. Notepad
  • Copy the following lines to the snomaxis.xml text file:
<?xml version="1.0" encoding="UTF-8"?>
 <SnomIPPhoneImageFile state="relevant" track="no" dtmf="on" >
 <fetch mil="100">http://<ip-address>/local/viewer/snomaxis.xml</fetch>
  • Replace the two <ip-address> tags with the IP address of your camera.
  • Save the file.
  • Etablish a FTP connection to the IP camera, using e.g. the PC tool WinSCP. Use the same username and password as the login on the webinterface.
  • Navigate to the following folder: /mnt/flash/etc/httpd/html/viewer
  • Copy the snomaxis.xml into the folder.
  • Close the FTP connection.

Firmware update of Snom phone

In order to support video, the Snom phone must have the correct firmware. The firmware is uploaded using a TFTP server.

Upgrade procedure:

  • Download firmware for the relevant Snom model from the AlphaWiki download site
    • Model 820: Version
    • Model 821: Version
    • Model 760: Version
  • Unzip the file. Remember in which folder you stored the file
  • Start a TFTP server, and browse to the folder which contains the file. A TFTP server can be downloaded here: TFTP server
  • In the Snom webinterface, select Software Update and enter address tftp://[TFTPServer]/[file name], where [TFTPServer] = IP address of PC running the TFTP server and [file name] is the name of the downloaded .bin file.
    • Example: tftp://
  • Select Load, and watch the progress on the display of the Snom phone
