WMS Configuration 

Create a Dialplan procedure 

To be able to manage calls from the intercom, you need to create a separate Dialplan procedure:

  • Go to WMS -> Dialplan -> Dialplan rules
  • Click + to add a new procedure
  • Specify the called number ("333" in the example) and a number/ numbers (e.g. Call group) of users who can receive calls from the intercom

Note: You can also add a Called number used for managing calls from the Intercom to the existing procedure used for incoming calls ("users" for example).

Add an Intercom user

  • Go to WMS -> Users
  • Click + to add a new user
  • Fill in the following fields:
    • Full name: name of the intercom user
    • Extension: extension number used by the intercom
    • Dialplan: select the Dialplan procedure used by the intercom
    • License type: select Basic

Mobotix Configuration

Access the web interface

To be able to connect to the web interface, you need to know the IP address released to the intercom by the DHCP server used in your network (router or PBX).

First time access credentials: admin : meinsm 

SIP Client Settings

Fill in the following fields in SIP Accounts:


  • SIP Address: enter the extension number of the Intercom user and IP address/ domain name of PBX

  • Authentication: enter the extension number and SIP Password 

    How to generate the SIP Password:

    • Go to WMS -> Users and select the intercom extension (106 in our example)
    • Click Set passwords
    • Click on Generate near SIP/VoIP, copy this password from WMS
    • Click Ok to confirm
  • Server: enter IP address/ domain name of your PBX

Remote Control Settings

Setting these parameters allows using an unlock button (described in the next chapter).

      /record/current.jpg - picture URL

    • SIPAddHeader(Unlock-Button:1) adds an unlock button 
      where:
      1 - DTMF code to unlock the door

Example of video preview with an unlock button:
