Note: Make sure the box “Legacy Switch Code” is activated in Advanced Settings section. When this box is checked, the first code listed above does not require confirmation by pressing “*” (or # from the phone. If the box is not check, it might be necessary to press “*” from the phone to confirm the door opening.

Step 3. Door open function from Wildix IP phones

Go to WMS > Dialplan, select the procedure used for outgoing calls by the intercom extension (“doorphone” in our example)

You can open the door from any Wildix device, including WP, W-AIR, Smartphone applications, Web phone by answering a call and entering a code specified in “Electric Lock Switching Settings” of the intercom, in the format: [code], in our example: *1234#


You can add an unlock button on WP600AXX, allowing you to open the door from the call management window. Add Dialplan Custom Application: SIPAddHeader(Unlock-Button:*1234#)where “*1234#” is DTMF:

You can display an incoming video stream before answer on WP600AXX. Add Dialplan Custom Application, example:



  • admin:admin – username and password, if needed
  • – IP address of intercom
  • /api/camera/snapshot function which allows downloading images from an internal or external IP camera connected to the intercom
  • width=1280&height=960&fps=15 – can be video resolution and other parameters.

More info on camera snapshot api is available in 2N manuals:


Another example of using custom application to display video stream:


It is possible to display video stream from doorphone / IP cam in case you correctly indicate the path to the video stream (JPEG URL). In most cases it is possible to check whether the indicated path is correct and the camera is reachable, by trying to access the URL via the browser.

Dialplan example:


  • “500” is the number specified in the quick dial button menu of the intercom;
  • “Custom application” -> SIPAddHeader(Unlock-Button:*1234#) is necessary only for WP600AXX: it enables the unlock button on the phone display
  • “Call group” is the call destination, in our example a call group answers calls from the doorphone; you can specify your own destination (an extension, several extensions, a call group…)
