Configuration guide snom® D385N

This configuration guide describes how to set up a snom® D385N as an extension of your PBX and automatically display the Behnke Station's video on calls. We assume that the basic configuration of the snom® has already been made and that the device is accessible via the IP address in a browser. We only describe how to register the snom® with your PBX and setting up the video display. We also assume that the Behnke Station has already been set up as an extension of your PBX.

1. SIP registration

• Call up the web interface of the snom® in your browser and log in with your admin credentials. Then choose a free identity from the menu on the left.

  

• Fill in the fields with the SIP registration information of your PBX. Also make sure that "Identity active" is checked at the top. Then click on Apply below.

  Field snom® D385N	Value PBX
  Displayname	an arbitrary name
  Account	snoms® user ID on your PBX
  Password	SIP password
  Registrar	IP address of your PBX
  Authentication Username	SIP ID

  

2. Video display

NOTE: This function can only be implemented with Behnke Stations that have a USB camera or an IP camera integrated as a system camera.

2.1 Configuring the video display

In order to display the Behnke Station's video on the snom® during a call, you have to create an entry for the Behnke Station in your snom®'s directory.

To do this, click on "Directory" in the menu on the left of the snom's® web interface. In the "Add or edit entry" section, fill in the fields with the information about the Behnke Station as follows, and then click Add:

NOTE:
- You can find out the extension of the Behnke Station by making a call to the snom® from the Behnke Station. The extension is then shown on the display of the snom® as the caller's number.
- The password for accessing the camera can be found on the web interface of the Behnke Station in the "Camera" menu item, in the "IP camera" section, in the "Password" field.
- The other fields here are optional and do not have to be filled out.

2.2 Action URL

In order to retrieve the Behnke Station's video on your snom® you have to enter the action URL. By default the URL is:

http://<IP address of the Behnke Station>:8080/?key=<Camera password>&snom, for example:

http://192.168.0.8:8080/?key=Admin&snom

This URL is used to retrieve the video without encryption. If you prefer to retrieve it with encryption you can use this action URL instead:

https://192.168.0.8:8443/?key=Admin&snom

However, please note that when retrieving the video via HTTPS, fewer frames per second may be displayed, or the video may only be displayed with a delay. Also you will have to add the Behnke Station's TLS certificate as a trusted certificate on your snom®. To do this, please follow these steps:

• After you have created the phone book entry with the action URL for encrypted retrieval of the video in the snom®, trigger a call to the snom® from the Behnke Station. A message will appear on the snom's® display informing you that an encrypted connection has failed. Then click on "Certificates" in the menu on the left of the snom's® web interface.

  

• There you should find an entry for the Behnke Station's certificate on the "Unknown certificates" tab. Click "Add Exception" here.

  

• Then switch to the "Own Certificates" tab. If (Expired) is displayed in the "Validity" line, the snom® was unable to check the validity of the certificate. Then make sure that the snom® can obtain the correct time via NTP. If in doubt, contact your admin or your snom® support.

  

• Then call up the following URL in your browser:

  http://<IP address of the snom®>/dummy.htm?settings=save&check_fqdn_against_server_cert=off

After that, when triggering a call on the Behnke Station, you should see the corresponding video.

2.3 Additional parameters

The display of the video can be manipulated with additional parameters. You can simply append these parameters to the above action URL. It's also possible to use multiple parameters in the URL. Here is the full list of parameters:

• Parameter "horizontal position" (&x=<Position>):

  This parameter defines the horizontal position of the video on the snom's® display. If this parameter is not specified in the URL, the video will be displayed at horizontal position 0.
  
  Example:
  
  To display the video at horizontal position 15 of the snom's® display, use the following URL:
  
  http://192.168.0.8:8080/?key=Admin&snom&x=15

• Parameter "vertical position" (&y=<Position>):

  This parameter defines the vertical position of the video on the snom's® display. If this parameter is not specified in the URL, the video will be displayed at vertival position 0.
  
  Example:
  
  To display the video at vertical position 30 of the snom's® display, use the following URL:
  
  http://192.168.0.8:8080/?key=Admin&snom&y=30

• Parameter "maximum width" (&max_width=<Width>):

  This parameter defines the maximum width of the retrieved video. The Behnke Station can only scale the resolution of the camera with certain factors. With this parameter, the Behnke Station sends the video with the resolution that best fits the specified maximum width.
  
  Example:
  
  To retrieve the video with a maximum width of 480 pixels, use the following URL:
  
  http://192.168.0.8:8080/?key=Admin&snom&max_width=480

• Parameter "maximum height" (&max_height=<Height>):

  This parameter defines the maximum height of the retrieved video. can only scale the resolution of the camera with certain factors. With this parameter, the Behnke Station sends the video with the resolution that best fits the specified maximum height.
  
  Example:
  
  To retrieve the video with a maximum height of 272 pixels, use the following URL:
  
  http://192.168.0.8:8080/?key=Admin&snom&max_height=272

• Parameter "resolution" (&resolution=<Width>x<Height>):

  This parameter allows the video to be retrieved in a specific resolution. The Behnke Station scales the native resolution of the camera with the most suitable factor and, if necessary, crops or adjusts the edges of the video to fit. Please note that this procedure is computationally intensive and the video may be delayed or displayed with a lower frame rate.
  
  Example:
  
  To retrieve the image with a resolution of 480x272 pixels, use the following URL:
  
  http://192.168.0.8:8080/?key=Admin&snom&resolution=480x272

3. Direct SIP calls (for usage without PBX)

According to the information we have, SIP direct calls are not supported. If in doubt, please contact your snom® support.
