Registering a New Mitel Phone Extention + Handset

Log In To The Mitel Controller

  • Open Internet Explorer and type in the address of your Mitel controller. (IE will have to be used, in my experience the Mitel controller don’t work using other browsers).
  • Open System Administration Tool.
  • In the left pane click on Users and Devices > User and Device Configuration.
  • In the right panel it will display all your current configured extensions and users assigned. To add a new phone and extension click the Add drop down button and click Default user and device.



  • Enter the basic new profile details, new users name, department, email…
  • Enter the Extension number for the user under Service Profile > Number. (Check to make sure the number is un-allocated)
  • Select the Device Type. It’s important that you select the correct model as an error will occur when you connect the device to the network.

  • Click the Save button.
  • Plug in the handset and wait for the unit to connect and all being well will display the extension number.
  • Any further setup can be done with the phone connected.
