Add a free licence to Call Queues and Auto Attendants (Microsoft Teams)


A licence is required for Call Queues and Auto Attendants that have phone numbers associated to them. Previously you had to assign a paid for Phone System licence, but now we have the option to acquire a free ‘Phone System – Virtual User’ licence. Here’s the process…

From your Office 365 tenant go to ‘Billing’ -> ‘Purchase Services’. At the bottom of the page select ‘Add-ons’:

Look for ‘Phone System – Virtual User’ and select it:

Follow the check out process adding the number of licences you expect to require:

Note: You’ll probably want to un-tick ‘Automatically assign to all of your users with no licenses’

Once you have acquired the licences, you can create the Resource Accounts required for Auto Attendants and Call Queues from the Microsoft Teams admin center:

Then, like you would for any old user, assign the licences you just acquired to the Resource Accounts so they are ready to associate to your Call Queues and Auto Attendants. When you assign the licence make sure you select your location too:

Now just associate the applicable Phone

Hope that helps, any questions just ask below.



  1. Hello Andrew,
    Great news!
    Is there any impact to replace the current resource account with the old license to the new phone system virtual user?


  2. Very useful licensing info, thanks Andrew. Would you happen to know if the new ‘Phone System – Virtual User’ licences count towards the maximum amount of service number numbers available? Or do you still need “phone system” and “audio conferencing” licenses to bump that service number limit up?

    I’ll paste a brief snip from the online guide for this:

    “….The number of [Service] phone numbers is equal to the total number of Phone System and Audio Conferencing licenses and uses the following:
    If there are 1-25 licenses then 5 telephone numbers are given.
    If there are 26-49 licenses then 10 telephone numbers are given.
    If there are 50-99 licenses then 20 telephone numbers are given.
    If there are 100-149 licenses then 30 telephone numbers are given. ….”
